15 Perfectly Safe Things That Were Once Considered Dangerous

Lead paint in kids' rooms. Smoking. Flammable pajamas. It's easy to name items that are more dangerous than we realized. But some things people once considered dangerous aren't harmful at all. 

1. Dancing

Safety dance? More like deadly dance. In its 1926 article “Death of Girl, 17, Laid to Charleston Dance,” The Washington Post reported on a girl who perished after dancing the Charleston. The paper interviewed the girl's doctor, who blamed her death on the “extreme physical exercise” of this classic dance move, which he said was “particularly dangerous for young women.” 

But potential “inflammation of the peritoneum” wasn't the only thing to be concerned about when flitting across the dance floor. Even the most traditional of dances could do serious damage and lead to all sorts of evil. “The high kick, displaying bare legs and arms of our little girls in the presence of even small boys, cannot honestly be said to tend to beget in those children the highest sense of modesty, purity so greatly prized in our women,” a Dr. Waldron told a local ministerial association in 1925; his remarks were quoted in  The Pittsburgh Courier article “Flays Teaching of Dancing in Public School: ‘Display of Bare Legs is Hurtful’” [PDF]. “The folk dances become the way and door to the dancing school; the dancing school is the feeder to the dance hall and public ball room and these inturn [sic], load to the brothel,” the doctor said. “Statistics show from one-third to two-thirds of the prostitutes in our large cities come from the public dance halls and ballrooms.” 

While few are currently concerned about the risk of death by dancing, there are still associations between promiscuity and certain dance styles. Some schools have rigid rules about what's allowed at school dances—especially when it comes to the distance between partners—and other towns have gone full Footloose, outlawing dancing all together, either for religious reasons, the crime rate at nightclubs, or like one town in Wisconsin, for just a short-lived promotional stunt

2. Competitive Sports (for Girls)

According to 1920s wisdom, if a girl wants to stay desirable and get married, she must refrain from practicing competitive sports. “Too many athletics threaten to rob girls of their chief appeal to men,” warns a Victoria college headmistress in “Says Athletics Harm Girls: English Woman Warns Students Not to Lose Appeal to Men,” an article published in The Washington Post in 1922. “The modern girl is trying to do too much at football,” she continues. “Her charm, balance and poise will all be lost, and her dignity lowered if she endeavors to emulate man too closely.”

Worse still, if she participated in sports in high school, she risked wearing herself out, ruining her chances for future happiness. “Must I continue through my life half enjoying living just because I gave too much of myself to competitive sports, to win a few medals which lie unnoticed and tarnished in a box?” asks a married woman in the 1931 Chicago Daily Tribune article “Competitive Sports are Dangerous for High School Girls.”  

It wasn’t until World War II that women’s competitive sports gained greater acceptance. After women proved their strength by joining the workforce or enrolling in military service, “organizations for women in sport began to increase as sport became more competitive and intercollegiate and interscholastic competition spread.” The Civil Rights movement in conjunction with Second Wave feminism also aided in the growing presence of women’s competitive sports.

3. Licking Stamps

Back in 1916—when snail mail was the norm, and before stamps evolved into stickers—The New York Times warned against the dangers of stamp licking. “Aside from hygienic reasons, it is dangerous to lick postage stamps on the ground that the stamps are bacteria-laden and under favorable conditions might easily convey pathogenic types especially colon, diphtheria, and tubercle bacilli,” said the Philadelphia scientists who conducted the study. 

A mere four years later, J. Diner and G. Horstman—two members of the American Pharmaceutical Association—disproved this theory. A 1920 article in The Boston Daily Globe quoted the study originally printed in American Medicine, saying, “The hygienic reason that people should not lick postage stamps is certainly sound. Nevertheless this practice is scarcely to be construed as a potential danger compared with eating and drinking which are so essential for sustenance but are responsible for a large measure of bacteriological contamination of the oral cavity.”

On that note, Seinfeld fans may wonder whether Susan could have actually died by licking all those cheap wedding invitation envelopes. Thomas P. Connelly, D.D.S., says no. “In general terms, most envelope glue is produced from gum arabic, which comes from tree sap,” he explains in a piece for The Huffington Post in 2011. “It is safe for humans and is also used in some other things we eat (M&Ms, gumdrops, etc.). The glue can also be more petroleum-based, as we can see by this answer from someone in the UK post office. But either way, it would appear that the glue is indeed safe. This goes the same if you ingest it, or if you cut your tongue while licking.”

4. The Color Purple

In the early 1900s, an interior decorator would never choose the color purple. A Boston Globe article from 1903—titled “Dangerous Tints: Some Colors Will Drive a Person Mad if the Eyes Are Continually Looking at Them”—called it "the most dangerous color there is":

If purple walls and a red tinted window surrounded you for a month with no color but purple around you, by the end of that time you would be a mad-man. No matter how strong your brain might be it would not stand the strain, and it is doubtful if you would ever recover your reason.

That wasn't the only color to avoid. Scarlet could push you into a murderous rage, while blue “excites the imagination and gives a craving for music and stagecraft, but it has a reaction that wrecks the nerves.” Meanwhile, “Solitary confinement in a yellow cell … will weaken any system and produce chronic hysteria,” and “sheer dead white, unbroken, will destroy your eyesight.”

But according to color expert Kate Smith, purple has the power to calm the nerves, improve the mood, and even inspire creativity. Why else would Harold choose a purple crayon? 

5. Dungeons and Dragons

D&D came under fire in the 1980s when suicides and murders were loosely linked to the game. A few years ago, Mental_Floss compiled a list of complaints against the fantasy role-playing game, including ones that mention cults, witchcraft, Satan, and murder. 

One mother was concerned by the amount of time and attention her kids and their friends devoted to the game. “They're always planning what they will do the next time. Kids have lost jobs, flunked out of school. They totally confuse reality and fantasy," she said. "It (the game) becomes their god."

6. Hanging onto Straps on Public Transportation

Ladies feeling under the weather in 1912 could blame public transportation. Not because there were germs lingering on the poles, or floating through the crowded street car, but because holding on to the straps—now replaced with rods—was “a frightful strain upon [your] internal organs,” according to the unnamed but "prominent" physician interviewed in 1912 for the Chicago Daily Tribune‘s “Strap Hanging Dangerous for Women.” According to the physician, "Women do not have the strong shoulder muscles that men possess, and while men use only their arm and shoulder muscles to steady themselves, women are obliged to use all the muscles in their bodies for the same purpose.” 

Lillian Russell, the author of the piece, even made it a political issue, saying, “It is high time that women were granted the rights of suffrage, for without suffrage they have neither seats in the cars nor the votes to protect themselves against such a horde of so-called men.”

Hanging on straps might no longer be considered dangerous for ladies, but seating on public transportation can still be a contentious and gendered issue. At least there are taxis.   

7. Where's Waldo? and other children's books

It’s hard to find Waldo among the crowded pages of a Where’s Waldo? book, let alone notice every detail hidden among the illustration. But once a kid in Long Island found a woman’s partially exposed breast on the beach page in the first book of the series, chaos—in the form of overly-concerned parents—ensued. The woman's breast, described as “about the size of the lead tip of a pencil,” caused the book to be banned from that town's school library in 1993. Other children’s books that have been pulled from the shelves include A. A. Milne’s Winnie the Pooh, Sylvester and the Magic Pebble by William Steig, and—in an unfortunate mix upBrown Bear, Brown Bear, What Do You See? by Bill Martin Jr.

8. Gum

Your mother might have told you never to swallow your gum because it would stick in your gut for 7 years. That might be a good way to scare a child into throwing their chewed gum in the trash, but this claim is entirely false. Yes, the gum isn’t broken down like other food, but it’ll still pass through your digestive system at a normal rate. That being said, it’s still not a great thing to do.

9. Sitting Too Close to the TV

Before TVs had flat screens, hundreds of channels, and crystal clear imaging, they were clunky and emitted radiation that could potentially worsen the viewer’s eyesight after prolonged exposure. However, in 1967, a “factory error” caused some defective General Electric televisions to emit 10 to 100,000 times the amount of radiation health officials deemed acceptable. GE recalled the TVs and updated their new models with a leaded glass shield surrounding the tubes inside the television to solve the problem.

Radiation isn’t something to worry about anymore, but you can still strain your eyes if you spend too much time staring at a screen—so with our iPhones and our computers and all of our other devices, television is the least of our problems. 

10. The Tomato

Paired with the wrong platter, a tomato had the power to kill. When European aristocrats became sick and died after eating tomatoes, the fruit was dubbed the “poison apple.” It was later discovered that the tomato itself wasn't deadly—but its high acidity caused it to “leach lead” from the pewter plate, resulting in lead poisoning. But the tomato’s reputation was set.

The tomato’s sad tale continued when the Green Tomato Worm invaded tomato patches across New York in the 1830s. Personal accounts of encounters with the worms resulted in rumors about how poisonous they were. It was believed that Ralph Waldo Emerson thought they were “an object of much terror, it being currently regarded as poisonous and imparting a poisonous quality to the fruit if it should chance to crawl upon it." The worm turned out to be totally harmless, people’s fears eventually subsided—and the tomato became a garden and salad staple.

11. Tea

In the 19th century, if an Irish peasant woman were drinking tea, it meant something else was being put on the back burner—something far more important, like her domestic duties. According to Dr. Helen O’Connell, a lecturer at Durham University, and author of “'A Raking Pot of Tea’: Consumption and Excess in Early Nineteenth Century Ireland,” published in Literature and History journal, “Drinking tea was thought to threaten traditional ways.” A tea break among women could lead to them plotting a rebellion or engaging in political discussion, and publicly distributed pamphlets warned against the dangers of the drink. Now we just consider it a nice alternative to coffee, which was also once considered dangerous

12. Clothes

“If the doctors are to be believed, the wearing of clothes is more dangerous to human life than their utter absence would be,” wrote the authors of the 1901 Boston Daily Globe article “Don’t Wear Clothes: That is, if You Would be Entirely Healthy…"  The British doctors who were consulted for the piece advised against wearing cotton and linen as well as garters and waistcoats, which they argued “are a permanent menace to life and health.”

Their reasoning is partially accurate—the body does breathe through both the lungs and the skin (despite what all of those internet myth sites will tell you), and there are some fabrics that are less “breathable” than others—but “nonporous clothing” isn’t quite as “disastrous” as they seem to have thought. 

Today, we know that cotton is one of the better fabric options available to us; some synthetic materials can cause rashes and skin irritation. However, there have been recent articles about the danger of some clothes—not because their “clammy surface ... imparts any variety of cold, up to and including pneumonia,” but because some dyes include toxins as a result of polluted water near the factories [PDF].

13. Writing Letters

Just a glance at a person's tweets, blog posts, and status updates can be enough to tell you everything there is to know about their problems. But oversharing isn’t a new epidemic caused by the Internet. In 1898, Amelia E. Barr wrote a chapter called “Dangerous Letter Writing” in her book Maids Wives and Bachelors in which she said “Young women are proverbially fond of playing with edged tools ... And of all such dangerous playthings a habit of promiscuous, careless letter-writing is the worst; for in most cases the danger is not obvious at the time, and the writer may even have forgotten her imprudence when she has to meet the consequences.” Barr credits cheaper postage for the impulsive way girls wrote overly sentimental letters and sent them off immediately.

In a highly prescient passage, she writes,

The abuse of letter-writing is one of the greatest trials of the epoch ... Every one cries out, and insists upon your listening. They write events while they are only happening. People unknown intrude upon your time and take possession of it. Enmities and friendships thousands of miles away scold or caress … For a mere nothing—a yes, or a no—idle, gushing people fire off continual notes and insist upon answers.

Letter writing may no longer be considered dangerous, but thanks to cell phones, computers, and all other communication enabled gadgetry, it's definitely still a nuisance. 

14. Public Toilets

Are you a hoverer or a toilet seat cover user? There's very little need to be putting in that extra effort when using a public restroom, because despite what you might have heard, it's impossible to contract a sexually transmitted disease just by sitting on a toilet. 

Donald G. McNeil Jr., a science and health reporter at The New York Times, attributes the fear of contracting a venereal disease from the toilet seat to an age old excuse. In response to a reader's question about the dangers of toilet seats, he explained that the STD myth was probably a result of cheating partners refusing to admit their infidelity when their partners angrily ask them about why he or she "suddenly has symptoms of syphilis, gonorrhea, pubic lice, or any other unpleasantry." Instead of coming clean, the unfaithful partner can easily say “I have no idea, dear—I must have gotten it from a toilet seat..." and then move on without an argument. 

Non-sexually transmitted diseases like various flesh-eating bacteria, the norovirus, or E. Coli are carried through vomit or feces, both of which are visible and thus avoidable. And far as other germs go, as long as the skin on your rear end and thighs is fully intact—thick skin works as a barrier—there's almost nothing to be worried about. 

That's not to say that there aren't germs on a toilet seat—in fact, there's an average of 50 bacteria per square inch on one's surface—but compared to a cutting board, a kitchen sponge, or your cell phone, toilet seats are cleaner. Just something to think about the next time you stick your iPhone next to your pillow. 

15. Air conditioning

The invention and subsequent increase in accessibility and affordability of air conditioning in the 1920s and '30s brought a general sigh of relief to homeowners and office workers used to sweating through the summer months. But in Washington D.C., some government officials didn’t give the new technological addition to the Senate chamber such a warm welcome. In May 1929, John E. Rankin, a Democrat from Mississippi, filed a complaint about the chilly air temperature in the chamber, saying, "This is regular Republican atmosphere, and it is enough to kill anybody if it continues." 

Rankin was wrong. In fact, according to a 2013 study, since 1960, air conditioning has cut heat-related deaths by 80 percent. "The likelihood of a premature death on an extremely hot day between 1929 and 1959 was 2.5 percent," and has since dropped to less than 0.5 percent.

Kodak’s New Cameras Don't Just Take Photos—They Also Print Them

Snapping a photo and immediately sharing it on social media is definitely convenient, but there’s still something so satisfying about having the printed photo—like you’re actually holding the memory in your hands. Kodak’s new STEP cameras now offer the best of both worlds.

As its name implies, the Kodak STEP Instant Print Digital Camera, available for $70 on Amazon, lets you take a picture and print it out on that very same device. Not only do you get to skip the irksome process of uploading photos to your computer and printing them on your bulky, non-portable printer (or worse yet, having to wait for your local pharmacy to print them for you), but you never need to bother with ink cartridges or toner, either. The Kodak STEP comes with special 2-inch-by-3-inch printing paper inlaid with color crystals that bring your image to life. There’s also an adhesive layer on the back, so you can easily stick your photos to laptop covers, scrapbooks, or whatever else could use a little adornment.

There's a 10-second self-timer, so you don't have to ask strangers to take your group photos.Kodak

For those of you who want to give your photos some added flair, you might like the Kodak STEP Touch, available for $130 from Amazon. It’s similar to the regular Kodak STEP, but the LCD touch screen allows you to edit your photos before you print them; you can also shoot short videos and even share your content straight to social media.

If you want to print photos from your smartphone gallery, there's the Kodak STEP Instant Mobile Photo Printer. This portable $80 printer connects to any iOS or Android device with Bluetooth capabilities and can print whatever photos you send to it.

The Kodak STEP Instant Mobile Photo Printer connects to an app that allows you to add filters and other effects to your photos. Kodak

All three Kodak STEP devices come with some of that magical printer paper, but you can order additional refills, too—a 20-sheet set costs $8 on Amazon.

16 Facts About The Other Guys On Its 10th Anniversary, Courtesy of Adam McKay

Mark Wahlberg and Will Ferrell star in Adam McKay's The Other Guys (2010).

August marks the 10th anniversary of The Other Guys, director Adam McKay’s send-up, and tribute, to the buddy cop movies that have been a Hollywood mainstay for decades. Will Ferrell and Mark Wahlberg play Detectives Allen Gamble and Terry Hoitz, two disgraced and otherwise dismissed desk jockeys who inadvertently uncover a massive financial scandal at the exact moment when corporate malfeasance begins grabbing overdue newspaper headlines. The duo’s comic chemistry thrives on Ferrell’s bookish awkwardness juxtaposed with Wahlberg’s macho exasperation, while McKay (working with writer Chris Henchy) exercises a growing social consciousness against the backdrop of one of cinema’s most familiar and durable genres. Supporting performances by Eva Mendes, Michael Keaton, and Steve Coogan, plus cameos by Dwayne "The Rock" Johnson and Samuel L. Jackson (not to mention a murderer’s row of up-and-coming comedians and improvisers) breathe unforgettable life into an escalating series of side-splitting scenarios.

McKay’s most vivid memory of the shoot, he tells Mental Floss, was of the cinematic and gastronomic indulgence he enjoyed shooting a (for him) robustly-budgeted action movie in New York City. “I think I put on literally 25 pounds during that shoot,” he says. “At the end, my wife just looked at me and was like, 'You look as big as a house.' I mean, some days my body would hurt from laughing all day, and then I just ate like chicken parm sandwiches and pizza.

"That's the closest I've come to a full-on decadent Hollywood movie," McKay continues. "We had a really big budget. We were in New York City. We had cars blowing up. We had all these big actors everywhere. It's still, by the way, a budget that's probably half of a Marvel movie or a Michael Bay movie. But that's the closest I've ever come to feeling like Tony Scott and that kind of world."

Exclusive to Mental Floss, check out these behind-the-scenes tidbits and trivia from the making of The Other Guys, straight from McKay himself.

1. The Other Guys started with the unlikely pairing of Mark Wahlberg and Will Ferrell—as dinner companions.

"We went to a little Italian place off Santa Monica and the energy between the two of them was really funny," McKay recalled of what kicked off the idea for Will Ferrell and Mark Wahlberg's on-screen pairing. "Mark's a Boston guy, athlete, tough, boxer; Will's big—Will's 6-foot-3 and definitely an athlete and no pushover—but at the same time, at root, kind of a sweetheart. And they just had a funny dynamic between them. I kept laughing the whole night. And that was really what launched it."

2. Adam McKay didn’t set out to make The Other Guys a parody, but Hollywood quickly taught him not to edge too closely to familiar properties.

"There was some movie that came out about two 'star' cops. And I jokingly said, 'We should do the movie about the cops in the background of the star cops,'" McKay says. "Because they were doing an A-Team movie, I said, 'We should call ours The B-Team.' We may have even announced the movie as that, and someone back-channeled us, like, 'By the way, don't call your movie The B-Team. We're not going to sue you, but like, just don't do that.'"

3. As appealing as it was to send up buddy-cop movie conventions, then- (and still-) current events helped solidify The Other Guys's themes.

"The other big component was that the financial collapse was actively happening," McKay says of the timing of The Other Guys. "We kept talking about how you can't do a jeopardy plot that’s about drug smugglers—like we'll be looking back wistfully at the days of drug smugglers and safe crackers and bank robbers. And so a big part of it was: How do you do a modern cop buddy film when banks have disappeared trillions of dollars and millions of people have lost their homes through this kind of bureaucratic malfeasance? And that launched Ferrell’s character, a forensic accountant into paperwork—and the idea was that the new cop heroes are going to be bureaucrats who are into paperwork."

4. Michael Keaton’s repeated TLC references were written into The Other Guys script, though Adam McKay wasn't sure how well the running joke would translate.

A running joke in The Other Guys has Michael Keaton's Captain Gene continually quoting TLC songs. "We had done a couple readings of the script where it played really well, not that that means it's going to play funny in the final movie," McKay says. "We've had bits that killed in read-throughs, and then they go in the final cut and something about the rhythm just doesn't work. We were fairly confident in that joke. There are other times though where you do discover the bit and you're improvising, you're throwing out alternatives, the actors are playing around, and you discover a bit. Then I'll turn to Kate Hardman, our script supervisor and say, 'Alright, we’ve got to keep that one alive.' And then in future scenes, she would remind me, 'Remember, you had this joke you wanted to keep alive' and I'll get one take where we do it."

5. Dirty Mike and the Boys, on the other hand, were not in the original script.

"Rob Huebel improvised the line 'soup kitchen' and we kept joking about Dirty Mike and The Boys. The scene where I show up with our DP Oliver Wood, [our property master] Jimmy Mazzola, and our producer Pat Crowley, and we're Dirty Mike and the Boys, was not scripted," McKay explains. "That came out of us loving Huebel’s improv so much that we knew we had to put Dirty Mike and the Boys in the movie. That was a perfect example where improv spawned a bit that ended up running through the movie."

6. The scene involving Allen’s ex-girlfriend “Christinith” was inspired not just by the particular way some people spell or pronounce their names, but by their annoyance when it's mispronounced.

"Obviously it was a running joke that very beautiful women love Allen Gamble," McKay says. "And we were joking about people through the years who have names they want pronounced a certain way and they're oddly hostile about it. There was someone we'd known who was named Anna, but she wanted to be called 'Ana,' and if you called her Anna, she would get mad and I'd be like, 'Wait a minute, what? You can't get mad about that.' So that was where the Christinith joke came from."

7. Will Ferrell’s “Gator” alter ego in The Other Guys was created to further develop the film’s “paper-pushers as heroes” idea.

"The character [Allen] was a guy who appears very mousy and very beta and quiet and we just kept kicking around the idea of: What's power now? What's a hero now? And we had this idea that the reason that Allen Gamble was so conservative and buttoned-down was that he had kind of let his power out once before and it hadn't gone very well," McKay explained of the many dichotomies of Ferrell's character. "And then we just started laughing about the idea that he became a pimp and didn't realize it. So that was the joke—the idea that he’s like, 'No, no, no, I'm helping them run a dating service.' 'No, you were a pimp.' And the lifestyle pulling him down without him really realizing what he's become. The thing that makes me laugh the hardest is when he's first talking to the girl in college, she's just going, 'I could go on dates with guys.' 'Oh yeah. I can make sure to collect the money.' It’s so innocent."

8. Adam McKay and his collaborators refined a unique technical process leading up to The Other Guys to keep track of the many variations attempted, and often improvised, during production.

"Brent White, the editor on The Other Guys, has this great system where you can go to each line of the script and click it and all the alt versions of it will be underneath it," McKay explains. "That was really a breakthrough, and once he really got that system going, it changed a lot of things. Every version, every permutation of the joke is right in front of you, and it made the whole thing easier to sort."

9. The Other Guys composer Jon Brion is a musical chameleon, but Adam McKay didn’t direct him to draw on the sound of, say, Michael Kamen’s Lethal Weapon scores for Allen and Terry’s themes.

"A lot of movies I did with Will are always kind of in between an original story and a parody," McKay says. "We want them to be original, but they're clearly messing around with the tropes of the genre that you're used to. So the trick was I wanted it to sound like a cop score, but I also wanted it to be good. So we kept kind of batting that around."

10. The Oscar-worthy end credits song “Pimps Don’t Cry” emerged from a need for actress Eva Mendes to have a melody to sing, and Jon Brion’s chops corralling heavy hitters for a comedy-soul classic.

Will Ferrell and Eva Mendes in The Other Guys (2010).Macall Polay/Columbia TriStar Marketing Group, Inc.

"We just wrote 'Pimps Don't Cry' for the scene," McKay explains. "When [Eva Mendes] sang it, we're like, wait a minute, can we record this? And, of course, Jon Brion knows everyone and has access to studios. So before you know it, we had CeeLo Green in there and it turned out Eva Mendes could sing. We recorded a whole track and I think even shot a video. But it came out of the scene. The actors were like, 'Well, what's the melody?' And we're like, 'Jon, you want to write something?' And then of course I was like, I gotta hear that song!"

11. Adam McKay explored the idea of Pop-Up Video-style detours in The Other Guys, but couldn’t figure out how to pull it off in the pre-streaming era.

"We had a thing that we were going to try and do in the movie where we would freeze-frame scenes and then a little box would pop out and show something from a couple months later. That was a style that was written into the script we had happening a bunch of times, and we could not get it to work. It's funny because now I know how I would do it, but at that time we just couldn't [make it work]."

12. The Other Guys's planned “flash-forward” scenes also included future President Donald Trump, whose Trump Tower gets blown up in the opening scene.

Future president Donald Trump filmed a cameo for The Other Guys, but it didn't make the final cut. "Donald Trump just basically wants to get paid," McKay says. "So if you show up and you write out a check for a certain amount of money, I can't remember what the amount was, $75,000 or $100,000 or something, he'll do it. Pretty much anyone could go to him and be like, 'Here's a check for $75,000,' and he will do it. Never in a trillion years imagining the guy would become president. He sort of was a New York joke for years, and Trump Tower was kind of known as being this cheeseball place, so it was a pure joke. But when we put it in the movie, we were like, 'Donald Trump’s so cheesy and cheap, let's not put this in the movie.' Even for the silly movie we were doing, it felt cheeseball, so we ended up cutting it out."

13. If there was a scene in The Other Guys that gave Adam McKay the “tingle in his balls” as a filmmaker that Allen and Terry feel while pursuing bad guys, it was the “Aim for the bushes” scene that sets up the whole film.

"I mean, that's one of my all-time favorite moments from anything I've ever been involved in," McKay says of his favorite scene. "I would say the family prayer scene in Talladega Nights, the Jenga tower scene in The Big Short, the other one was in Anchorman, when Jack Black kicks the dog off the bridge where the audience made this weird sound and were so stunned by it. And then Danson and Highsmith jumping off the building —oh my god, I had so much fun watching that with test audiences. No one saw it coming.

"[The Rock and Samuel L. Jackson] are such big stars that just in a million years, no one imagined it. When the guys were falling off the tower, they were so convinced they weren't going to die. You would hear people in the audience go, 'Yeah right, they would never survive that.' But when they hit, there was such a collective inhale from the whole audience, and then just explosion of laughter. But the other great moment for that was when I was in the edit with Erica Weis, our music editor and music supervisor, and we discovered the Foo Fighters song for that moment. It was just so perfectly over-the-top and a little cheesy, yet plausible. Of course the filmmakers would play this song! The entire puzzle clicked together perfectly when that song went in."

14. Adam McKay credits his executive producer for the coup of recruiting Dwayne Johnson and Samuel L. Jackson as the “star cops” by whose police work Allen and Terry would be measured.

"I give [executive producer] Kevin Messick a lot of credit for that casting," McKay says. "We wanted two big action stars that you would never think would die in a movie, and boy, Kevin really helped us get them. He had some connection to Dwayne Johnson, and he worked the phones to really help us get Sam Jackson. I saw Sam Jackson years later and he's like, 'People keep asking me if we're going to do a spinoff movie with these guys.' I was like, oh man, that could be fun. And Dwayne Johnson told me too he had people come up to him and mention those characters all the time."

15. The original ending to The Other Guys was even more bleak than the statistics that play over the end credits.

"We had this whole ending where like they bust Steve Coogan's character Ershon and they pull the thing together and they take him in and it turns out Congress has changed the laws and what he's done is no longer illegal," McKay explains. "I wish we had ended with that. That would have been a better ending. And then we had this other ending with Derek Jeter, where he comes out and it turns out he's connected to this whole underground thing that's fighting against the big banks. That's in the TV version they air, but it didn't really work ... when I say work, I don't care if the audience loved it. It didn't work for me with the narrative when we a test screened it. So I didn't think we stuck the landing on the ending on it."

16. Adam McKay always worked culturally relevant themes into his films, but The Other Guys galvanized this approach going forward, reflected more prominently in The Big Short and Vice.

"Ferrell and I would do these comedies, and we would always have something [else] going on in them," McKay says of his desire to weave bigger themes into his films. "Even Step Brothers was kind of about how consumer culture turns us into big giant children. And the Iraq War was such a horrible tragedy and disaster that right around that time, and that’s when I started thinking, 'I just gotta do some stuff that's more overt.' When the financial collapse hit, it was just like, all bets are off. So yeah, we tried to craft the whole movie like a comedic allegory for the financial collapse. If you look at the movie, they keep ignoring their union. And then there’s a big financier covering losses by taking money from workers. Of course, when the movie came out, no one cared—the movie just played as a comedy. Except for the ending credits, people really didn't catch it at all. Which I don't blame them! I think it was a little bit of an experiment in that sense. And the good news is the movie’s funny and I really love how it turned out."
