For 50 years and more than 4500 episodes, Sesame Street has been imparting valuable moral, ethical, and social lessons to young audiences using a sprawling cast of puppets. The Sesame characters—Big Bird, Elmo, Oscar the Grouch, Cookie Monster, Bert and Ernie, the Count, and others—have become instantly recognizable to generations of viewers. But behind every memorable character is a human performer, one tasked with juggling the technical demands of puppet operation without losing the humor and heart that makes their furry counterpart so memorable.

To get a better sense of what goes into this unique skill set, Mental Floss spoke with three veteran Sesame Street performers during the show’s semicentennial celebration. Here’s what they had to say about crossed puppet eyes, grooming habits, and enjoying a long career finessing felt.

1. Sesame Street puppeteers usually get started lending a (right) hand.

Though there’s no definitive set of directions for puppeteers to get to Sesame Street, a number of performers selected to work on the show begin as apprentices with one specific task: operating the right hand of characters alongside the veteran cast members. “A lot of performers will almost only do right hands for a very long time,” Ryan Dillon, the puppeteer behind Elmo, tells Mental Floss. “Some characters, like Cookie Monster, require two performers with two practical hands.”

Dillon started working on Sesame Street in 2005 at the age of 17. He performed as a right hand and as supporting characters for years before scoring the Elmo role in 2013. Throughout that training, he accompanied the main puppeteer, who uses their dominant (usually right) hand to control the mouth and the other to control the left hand. The newcomer will manipulate the right, a duty informally known as right handing. “It’s a great training ground,” Dillon says. “You’re working directly next to a performer with years of experience. You become one character together.”

2. Sesame Street puppeteers have tricks for making their characters emote.

Peter Linz, who portrays Ernie (among other characters) on the series, tells Mental Floss that getting a puppet to exhibit a personality takes some finessing. “You have to show the entire range of human emotion through something that doesn’t have an expression,” he says. Linz, who also teaches classes on puppeteering, says that there are some techniques to get puppets to show off their mood, however. “You can make them look sad by having them look down. You can get them to smile by opening their mouth. If they’re angry, maybe you close their mouth and then shake their arms ever so slightly. There are degrees of subtlety in all of that.”

Linz says the audience does part of that work themselves, projecting their own feelings onto a puppet. The ultimate proof might be in the example of Miss Piggy. While not a Sesame Street cast member, Linz says it’s telling that people often seem to believe the vivacious and flirtatious porcine character bats her eyes. “She can’t,” he says. The puppet doesn’t have that ability.

3. Not all Sesame Street puppets can perform the same tasks.

Sesame Street utilizes three major varieties of character. There’s the full-body puppet, like Big Bird and Snuffleupagus; “bag” puppets with two articulated hands, like Cookie Monster; and hand-and-rod puppets that have arms controlled by thin rods. “Elmo is a hand-and-rod puppet,” Dillon says. “[The difference means] some puppets can do things others can’t. Cookie Monster can pick things up. Elmo can, but it takes longer. You need to stop [filming] and attach something to his hands with tape or a pin.”

4. Sesame Street puppeteers rely on a key design element to connect to their audience.

It can be difficult to communicate that a puppet is able to focus a pair of fixed eyes on something, whether it’s another character, an object, or the audience. But Linz says that the Sesame Street crew and the rest of the Muppets were designed by Henson with that in mind. “The eyes are just two black dots against a white background,” he says. “But all the characters are ever so slightly cross-eyed. There’s a triangle between the eyes and nose and a point where it looks like they’re looking right into the camera.” It’s a sensitive illusion. Turning the puppet even slightly, he says, and they will wind up looking at something else.

5. Sesame Street puppeteers can spend their entire day crouched on the floor.

Being a Sesame Street puppeteer requires more than just having performing chops. On set, characters that may be at waist level with their human co-stars are operated by performers crouched below frame, often on wheeled boards called rollies. “The first day or two, your back and everything else is sore,” Dillon says. “It engages your whole body. Your arm is up in the air performing.” Some actors, Dillon says, have developed knee issues as a result of a career bent over. Fortunately, not every scene requires contortions. Some sets are built raised so performers can stand up straight. Other times, they’ll have to situate themselves horizontally. Scenes set on a stoop usually mean the performer is lying down behind the steps.

6. Sesame Street puppeteers have input into character design.

Lurking in the offices of Sesame Workshop is a puppet factory that, according to Dillon, houses a number of "Anything Muppets"—blank designs that may one day be used as the template for a brand-new character. In 1991, performer Carmen Osbahr got an opportunity to get in on the ground floor of conceptualizing a character when she helped originate Rosita (top right), the first regular bilingual Muppet on the series. “They had a meeting and asked what I had in mind,” Osbahr tells Mental Floss. “I was able to tell them I wanted a monster and I wanted live hands because I wanted to be able to play a musical instrument. I wanted her to be active and colorful. I didn’t want a petite, tiny little monster.” Both Osahr and Rosita have been a presence on the show ever since.

7. Sesame Street puppeteers have material for a blooper reel, but you’ll probably never see it.

Puppet manipulation takes concentration and effort. Occasionally, the cast of Sesame Street can find themselves flubbing a take. According to Osbahr, that’s often due to trying to coordinate left and right hands. “The main thing is props,” she says. “Grabbing stuff is easy, but if you want to pour something into a cup or write a letter, that’s hard. You think you’ll have a glass but just miss it.” Performers can also fall off their rollies, sending their counterparts tumbling out of the frame.

8. Each Sesame Street character has a dedicated puppeteer—with a couple of exceptions.

When it comes to Sesame Street characters, there is one sacrosanct rule—aside from right handing, no puppet will have more than one puppeteer. “We feel strongly each Muppet has a dedicated performer,” Dillon says. “If there were two or three Elmos, you would see a copy of a copy.” However, illnesses or personal appearances can make that rule difficult to follow every time. If Dillon can’t make a shoot, a performer will step in to operate the puppet, with Dillon going in to provide the voice later.

The cast can also cover for one another if a scene requires two characters who are normally operated by the same actor. Both Bert and Grover, for example, are played by actor Eric Jacobson. If the two share screen time, Dillon might step in to perform one of them, with Jacobson recording his lines later.

9. Sesame Street puppeteers have a specific way of handling their puppets to keep them clean.

Day after day of manipulating puppets can lead to issues with cleanliness. Performer sweat can dampen the foam insides, while body oils and other contaminants can affect their fur coats. To avoid being dirtied, Linz says performers and production members try to pick up the puppets by the scruff of their necks. “We don’t want to put our oily hands on their faces,” Linz says. Puppets are also usually delivered to and from the set by a team of “Muppet wranglers,” and stored in the workshop where they’re built and maintained. To dry out a puppet, they’re sometimes placed on a wooden stand. A hair dryer set on low might also be used to dry a sweaty interior.

10. Sesame Street puppeteers work very, very closely together.

Owing to the frequent proximity of puppets in frame, Sesame Street puppeteers are usually working near or virtually over other performers. “We try to be very aware and conscious of the people around us,” Dillon says. “Mistakes happen. Elmo has big feet, and Abby Cadabby has big feet, so you’ll often hit the other person with a foot. It doesn’t hurt.”

11. Guest stars will talk directly to Sesame Street characters—not just the puppeteers.

Sesame Street has played host to many guest stars over the decades, from actors to First Lady Michelle Obama. According to Osbahr, their human guests will often address the character even off-camera. “Most everybody who visits us talks to the character like they’re alive,” she says. “The moment we bring a character down [to rest], we have a conversation, but it’s great to have a relationship with a character and a celebrity. They’ll talk to Elmo, Rosita, Cookie Monster, and we’re talking to them right back.”

12. Sesame Street puppeteers can take years to get fully comfortable with a character.

For many performers, it can take years before they feel like they’re fully inhabiting their character. “You can be so focused on doing something right, you forget to have fun with the character,” Osbahr says. “By the fourth season, that’s when I started letting go, taking risks, having fun. You stop having to think about it.”

Fortunately, it’s not uncommon for performers on Sesame Street to spend decades on the show, which means there's plenty of time to adjust. Carol Spinney, who portrayed Big Bird and Oscar the Grouch, retired in 2018 after 49 years as a cast member. Osbahr says the familial atmosphere encourages longevity. “I’ve been with this group of people for 30 years,” she says. “We’ve shared a lot of incredible memories together.”

13. Sesame Street puppeteers can sometimes mourn a puppet who is declared “toast.”

Made of foam and other delicate materials, Sesame Street puppets have a shelf life. Depending on use, wear, and handling, they might last a few years before needing to be replaced. Linz says two new Ernies have recently been made after one began sloughing off foam inside, a symptom the production calls “toast” because the foam resembles toast crumbs.

Even with replacements, the legacy of characters can still live on. Linz uses an Ernie with the same mouth plate that was used by Jim Henson as far back as 1982.

14. Sesame Street puppeteers have to work backward.

The most surprising aspect of working as a Sesame Street puppeteer? According to Linz, it’s the fact that performers often have to essentially work backwards. Because they’re crouched below the camera frame, puppeteers need to watch a monitor placed low to the ground to see what the camera sees. “When you move your arm to the right, the arm on the monitor moves to the left,” he says. “You’re seeing the image the audience sees.”

15. Yes, Sesame Street puppets are technically Muppets.

Sometimes there's confusion over whether the puppets that appear on Sesame Street actually constitute Muppets, or whether that term is reserved for non-Sesame projects like The Muppet Show or other endeavors featuring Kermit, Miss Piggy, and the others. According to Dillon, any Henson-birthed or -inspired puppet is a Muppet. “It’s become a catch-all term for puppets,” he says. “It’s a brand name, like Kleenex. Jim Henson came up with the name. A Muppet is used for characters that he came up with."

11 Secrets of Astronauts

In the 60 or so years that the job has existed, astronauts have captured the public's imagination. And while many people might think they have some idea of what being an astronaut is like, thanks to the glut of portrayals in movies, real astronauts will tell you that working for NASA is much different from what you see on the screen. In between exciting tasks like spacewalks, they have to worry about less glamorous aspects of the job—like finding lost items that floated away and using the toilet in microgravity.

Mental Floss spoke with two former NASA astronauts about the realities of preparing for and experiencing life in space. Read on to learn about the most annoying parts of the job, the ways they have fun, and their honest opinions about astronaut food.

1. Astronauts come from a range of different fields.

There’s no one direct path to becoming an astronaut. If someone knows they want to be an astronaut from a young age, they need to build credentials in a specific field before they can get the attention of NASA. "They're looking for people who are qualified, meaning that they're high-achieving military people or people from civilian life, generally with an advanced degree," Mike Massimino, a former NASA astronaut and professor of mechanical engineering at Columbia University, tells Mental Floss.

To be considered for NASA’s astronaut program, candidates must have U.S. citizenship, hold a master's degree in a STEM field, and have at least two years of related post-grad professional experience or at least 1000 hours of pilot-in-command time on jet aircraft. Two years toward a doctoral program in STEM, a completed doctor of medicine or doctor of osteopathic medicine degree, or completion of a nationally recognized test pilot school program are also accepted in place of a master's degree. Because space flight crews require diverse skill sets, the criteria doesn’t get more specific than that.

"I was a Ph.D. research engineer professor when I was picked," Massimino says. "I've flown in space with engineers, with test pilots, helicopter pilots for the military. I've also flown in space with a geologist, I've flown in space with an oceanographer, and I've flown in space with a veterinarian. So it's really varied. There's not just one route."

2. Astronaut training involves everything from class work to military survival exercises.

Candidates accepted into the astronaut program must complete years of training before they're ready for spaceflight. A lot of that training takes place in the classroom and involves learning about different space vehicles and systems. Astronauts also undergo physical training in the real world. According to Garrett Reisman, former NASA astronaut and the director of space operations at SpaceX's headquarters in Hawthorne, California, one of the most intense courses has nothing to do with preparing for life in space.

"We do the same SERE [survive, evade, resist, escape] training that military aviators go through," he tells Mental Floss. "The idea is that if you fell out of an aircraft over enemy terrain, you got to know how to survive without help. You have to learn to live off the land, what plants you can eat, how to make a shelter and all those things."

The T-38 jets astronauts fly as part of their training have ejectable seats, so landing somewhere unfamiliar is a possibility. But astronauts only fly over the continental U.S., so they likely won't ever need to use the full extent of their SERE training. "What are the odds that you parachute down and there’s not a Starbucks right there?" Reisman jokes. "All you need to do is give me a Starbucks gift card and I’ll be fine."

3. Exercise is a vital part of the job.

Exercising is more than a way to pass time in space: It’s essential to an astronaut’s health. The human body isn’t used to moving around without the force of gravity, and for this reason, all astronauts must make resistance exercises part of their daily routine.

"You do have to spend two hours every day exercising," Reisman says. "If you're up there for a long period of time, you can lose a lot of your bone and your muscle mass if you do nothing, so the way we get around that is by doing intense resistance exercise."

Astronauts can lose up to 20 percent of their muscle mass on an 11-day space flight due to the lack of gravity [PDF]. But zero gravity also makes free weights useless, so instead, astronauts maintain their strength by using a device outfitted with two small canisters that create a vacuum they can pull against with a long bar. A bike and treadmill (with a harness) are also available on the International Space Station. Strength is required to perform certain emergency procedures when the ship re-enters Earth's gravitational field, so staying fit in space is vital.

4. Astronauts do most of their work on Earth.

In order to become one of the few people to travel to space, astronauts must be willing to do a lot of work at home. "A NASA astronaut’s job is mainly spending your time on Earth," Massimino says. "You're going to spend the vast majority of your time on the ground, either training or working on technical issues or helping other people fly." Throughout his nearly two decades with NASA, Massimino spent less than a month total in space. Reisman was with NASA for 12 years and spent a cumulative 107 days of his career in space.

5. Astronauts don't make as much money as you think.

One of the biggest misconceptions astronauts hear about their work relates to their salary. While they are paid decently, astronauts don’t collect the massive paychecks some people might assume comes with such a high-profile job. "We don't make a heck of a lot of money," Massimino says. "We make a standard government salary."

Astronauts are paid according to the federal government's General Schedule pay scale. Most federal jobs are assigned a General Schedule (GS) grade that determines their starting salary, and the pay increases as they gain experience. Astronauts either qualify for grades GS 13 or 14 (the highest grade is GS 15) and make between $104,898 and $161,141 per year. For comparison, Fish and Wildlife administrators are paid similarly at the right experience level.

6. Astronauts lose things (but not for long).

Even in a place as tight as a space station, astronauts still manage to misplace their belongings. Thanks to the lack of gravity, anything they let go of immediately drifts away, which can cause problems when they’re not paying attention. Massimino recalls one incident that happened to his crewmate Mike Good: "He had his grandfather’s watch with him, and he comes up to me and goes, 'Mass, I can’t find the watch.' We’re looking all over the place and I stop after a minute and go, 'Mike, it’s inside here somewhere.'"

They eventually found it trapped inside the airlock. The air filter is another common place where lost items end up: Without gravity interfering, the air flow will carry any floating objects there. "One thing we would say is, 'If you can’t find something, just wait,'" Massimino says. "You'd wake up in the morning and look at the filter and see like aspirin and a piece of Velcro or something, because everything eventually would get there."

7. Astronaut opinions on the food in space are mixed.

Despite its reputation, space food has some fans in the astronaut community. "Astronaut food is great," Massimino says. "We had ravioli, lasagna, shrimp cocktail, fajitas. It was fantastic."

Reisman holds a much different opinion of the meals he ate in space. "It’s terrible. You don’t go to the space station for the food," he says. While he didn’t love the American and Russian provisions that made up most of his diet in space, he did have nice things to say about food from other agencies. "The Japanese and the Europeans, when their astronauts would fly, they had special food that was provided by their space agencies. The Japanese sent up yakitori and miso soup and that was delicious. And the Europeans had pâté. That was much better."

8. Astronauts find time to have fun.

Between work, meals, and exercise, astronauts don’t have a ton of free time in space. Duties like maintenance, installing equipment, and conducting experiments take up the majority of their day. Sneaking in recreation usually means staying up past their scheduled bedtime, which Reisman confirms most astronauts do. One of his favorite activities to do aboard the International Space Station was taking pictures of Earth. "You could take photographs of places on Earth that are special to you. I got a picture of my hometown, which is pretty cool. As far as I know, no human ever photographed that particular town from space before."

9. Astronauts think movies set unrealistic standards.

The science isn’t the only thing that’s unrealistic about Hollywood’s portrayal of space travel. "I think the biggest misconception is that we're all tall and good-looking," Reisman says. When working as a technical advisor for 2019's Ad Astra, he jokingly brought up this gripe with the movie’s star Brad Pitt. "I said, 'I’m kind of pissed off at you. Think about who they cast to be astronauts in all these movies and TV shows. Matt Damon, Matthew McConaughey, George Clooney, Brad Pitt. People meet me and they’re disappointed.'"

Reisman doesn't hold this against the actors, however. Pitt reminded him that the stars portraying astronauts on screen have plenty to be envious of themselves. "Brad said: 'Well, Garrett, I can't actually fly a spaceship. The only talent I have is being able to stand in a certain spot and read something that someone else wrote. I got nothing else.'"

10. Going to the bathroom in space is an ordeal.

If you’ve ever wondered how astronauts poop in space, the answer is: with great difficulty. "Taking a dump was not easy," Reisman confirms. Without the help of gravity, using a toilet in space becomes a complicated operation. Astronauts must strap their feet down to keep from floating away and create a perfect seal between the toilet seat and their butt cheeks. The toilet itself uses a vacuum hose to suction up the waste. The process is so complex that using a space toilet is part of an astronaut’s training. It's not unusual for a bathroom break that normally takes a few minutes on Earth to last half an hour in space.

11. In such a competitive field, astronauts need to be persistent.

NASA's astronaut training program is extremely competitive. The agency selected just 12 people out of a pool of 18,353 candidates in 2017, which comes out to an acceptance rate of 0.065 percent. Massimino had to apply four times before he made it into the program.

"I was rejected outright twice while I was in grad school. The third time I got an interview and failed the eye exam, so was medically disqualified." NASA considers candidates with less than 20/20 vision today as long as it's correctable, but that wasn't the case when Massimino was applying. "I went through some vision training with an optometrist, and I was able to teach my eyes to see a little better. I was able to apply a fourth time, and I was picked on my fourth try."

According to Massimino, that level of commitment to his goal ended up being relevant to the job itself. "The job is a lot of late-night simulations, you have to pass exams, you have to work with your teammates. And unless you have a real interest in it, it's going to be tough."
