This Is Your Brain on Puns

Q. What do vegan zombies eat?
A. Graaaaaaaaaaaaains. 

If that joke made you groan like the undead, thank your bilateral processing abilities. Researchers studying the neuroscience of puns say that understanding them, even the bad ones, requires cooperation between both sides of the brain. They published their research in the journal Laterality: Asymmetries of Body, Brain and Cognition. 

Humor has a reputation for being transgressive, but all that boundary-pushing is only possible thanks to a system of internal rules. From knock-knock jokes to digs on someone’s mama, each class has its own standardized scaffolding. Some philosophers argue that humor itself depends on a formula: taking something familiar and giving it an unexpected—but not upsetting—twist. 

This “benign violation” setup is also at the heart of the pun. The joke up top takes a reader’s familiarity with the cliché of the lurching, brain-craving zombie, then uses a rhyme to add a surprising shade of meaning. Yes, we know that dissecting jokes isn’t funny. We’re done now.

Neuroscientists at the University of Windsor wondered how our brains would parse the two-step process of understanding puns. They were specifically curious to find out how the work was divvied up between the brain’s left and right hemispheres. 

To find out, they brought volunteers into the lab and sat them down in front of computers, which proceeded to display a series of easy, cheesy puns. (Ex.: “They replaced the baseball with an orange to add some zest to the game.”) Some of the puns showed up on the left side of the screen, where they would be processed first by the right side of the brain. The rest showed up on the right. The participants were timed to see how long it took them to get each joke, such as it was. 

The results showed that participants were quicker on the uptake when their puns appeared on the right side of the screen—that is, starting with the left side of their brains. This makes sense, co-author Lori Buchanan told Scientific American: “The left hemisphere is the linguistic hemisphere, so it’s the one that processes most of the language aspects of the pun, with the right hemisphere kicking in a bit later.” 

Understanding a pun, they found, requires input from both hemispheres. The left side introduces the standard, linguistic part of the sentence or joke—essentially setting up the setup—while the right side analyzes the punchline’s double meaning. 

That's probably more thought than most puns deserve. 

10 Delicious Facts About McDonald's Shamrock Shake

Many people overdo it with the drinking on St. Patrick's Day, but it's not always Guinness or Jameson that gets them into trouble. Sometimes it's the Shamrock Shake, McDonald's uniquely green and often elusive seasonal treat. Here’s the skinny on the 660-calorie indulgence.

1. The Shamrock Shake wasn't originally known as The Shamrock Shake.

The original name of the cult classic milkshake was slightly less alliterative. It was called the St. Patrick’s Day Green Milkshake. Catchy, no?

2. The Shamrock Shake is a charitable endeavor.

What does the Shamrock Shake have to do with the Ronald McDonald House and the Philadelphia Eagles? Everything, according to the fast food giant. When Eagles tight end Fred Hill’s daughter was being treated for leukemia in 1974, Fred and his wife spent a lot of time in waiting rooms and noticed many other emotionally depleted families doing the same. He thought it would be healthier for families if they had a place to call home while their children were being treated, so he used his football connections to get in touch with a local advertising agency that did work for Mickey D’s. They agreed to give profits from the Shamrock Shake toward a home near the Children’s Hospital in Philadelphia, which ended up becoming the first-ever Ronald McDonald House.

3. Uncle O'Grimacey used to be the Shamrock Shake's ambassador.

Back in the early ‘80s, a fairly offensive character named Uncle O’Grimacey was used to promote the seasonal shake.

4. No McDonald's restaurant is required to offer the Shamrock Shake.

In 2012, it was announced that, for the first time, the Shamrock Shake would be available in all McDonald's nationwide—but not all restaurants have to carry them. Regional managers decide whether their stores will carry the shakes each year.

5. Jimmy Fallon once depleted a New York City restaurant's entire Shamrock Shake supply.

If you’re a New Yorker and you didn’t get a much-craved Shamrock Shake in 2011, it’s probably Jimmy Fallon’s fault. When he caught wind that a Union Square Mickey D's had the elusive dessert, he totally cleaned them out—purchasing more than 100 shakes for his audience. New Yorkers were not pleased with Fallon.

6. The Shamrock Shake got an ice cream offshoot (that didn't fare so well).

Despite the smashing success of the shake, the Shamrock Sundae was a dismal failure. Introduced in 1980, it was discontinued after just a year. Apparently people prefer their unnaturally green desserts in shake form as opposed to scoop form. Though this year, they're trying again: in honor of the Shamrock Shake's 50th anniversary, McDonald's is also introducing an Oreo Shamrock McFlurry.

7. There have been many super-sized versions of the Shamrock Shake.

For a few years, a giant shake was poured into the Chicago River to help contribute to the green hue it’s dyed every year. A donation was also made to the Ronald McDonald House.

8. The McDonald's app will help you track down a Shamrock Shake.

Are you one of those unfortunate souls who has to hunt the shake down every year? McDonald's official app can help. In 2020, for the first time in three years, the Shamrock Shake will be offered at all McDonald's locations. If you're not sure of the nearest one near you, the McDonald's app has a full directory to help.

9. You can make your own Shamrock Shake at home.

If you still can’t find a shake, you have one other option: make your own.

10. In 2017, McDonald's engineered a special Shamrock Shake straw.

In 2017, McDonald's unveiled an amazing innovation for Shamrock Shake lovers: the STRAW. Short for Suction Tube for Reverse Axial Withdrawal, the STRAW was designed by real engineers at the aerospace and robotics engineering firms JACE and NK Labs—specifically with the Shamrock Shake in mind. What sets the device apart from conventional straws is the sharp bend in its shape and the three, eye-shaped holes in addition to the opening at the bottom end. The extra holes are positioned in a way that allows drinkers to take a sip of a new layered version of the frosty treat that’s equal parts top mint layer and bottom chocolate layer.

Why Are CVS Receipts So Incredibly Long?

If you’ve ever conducted business at one of the nearly 10,000 CVS Pharmacy locations in the United States and count yourself among one of the estimated 62 million members of the store's ExtraCare discount incentive program, you’ve probably been handed a receipt that is more scroll than slip. These transactional documents, which have been known to literally be several feet of thermal paper long and full of merchandise coupons, are often wadded or folded up like a bath towel and handed off to the consumer.

Is this an environmentally mindful practice? And do these coupons really keep people coming back for more?

CVS has stated that the lengthy receipts are intended to demonstrate the value of being an ExtraCare member by offering ExtraCare Rewards, typically a dollar or percentage amount off of a single item or purchase. Some of the receipt's oversized real estate is also taken up by a solicitation to participate in a satisfaction survey. (Though it’s not likely that one of the questions is about the length of the receipt.)

Simply put, the chain wants to vividly illustrate the benefits of being an ExtraCare member, which also helps the company by allowing them to track your purchase history. The idea is that the Russian novel-length receipt will excite consumers who feel as though a surplus of savings are being delivered right into their hands.

The problem is that the coupons are often quick to expire or can sometimes exclude sale items, registering disappointment when a returning customer presents a slip for $2 off a bar of soap.

You can, of course, opt out of receiving a paper receipt through your ExtraCare account online or via the app, though the process requires a few steps to complete. The coupons will then be sent digitally via your smartphone. Since introducing that paperless option in 2016, the company claims it has saved 3 billion inches of paper that would otherwise have been squeezed into a ball and stuffed into your glove compartment.

Alternately, you can always use it to replace a broken window blind.

Which brings us to the other and possibly most important motivation for those long receipts: Social media engagement. The more people express dismay at those long receipts, the more exposure CVS receives. Considering their 2018 merger with health insurance giant Aetna cost more than $70 billion, some free publicity could come in handy.
