Can a Computer Make a Meme?

How is language evolving on the internet? In this series on internet linguistics, Gretchen McCulloch breaks down the latest innovations in online communication.

There's something so delightfully human about memes. A few decades ago, no one would have predicted bizarre phenomena like LOLcat or doge. The best memes are satisfying in the way that a good joke is satisfying. Surely that's not something you can code into a computer, though a recent study by computational linguists William Yang Wang and Miaomiao Wen of Carnegie Mellon University tried to do just that. 

There were already researchers working on programing auto-generating descriptions of images, but that's not quite the same as generating meme-like image macros. First of all, not all images are suitable meme backgrounds. And even when they are, it's not enough to just describe the actual image itself—"white cat wearing bowtie sits at table" is not a meme-ish caption. Wang and Wen recognized that the key was that memes occur in genres or patterns to be followed.

Given a certain image, such as Scumbag Steve, Socially Awkward Penguin, or the Forever Alone face, the computer had to figure out which of thousands of possible captions would fit best. The first thing that the system would do was run the image through Google's reverse image search, which automatically assigns an image a few keywords based on similar images in its index. Those keywords were then used to search a list of 269,473 meme captions taken from memegenerator.net and cheezburger.com. Possible captions were ranked by comparing various features of the original image and the text, and the top-ranked caption was assigned to the image. So there is nothing new here—the computer just has to tie existing joke-text to an existing meme image.

When all these steps are taken together, how did the computer do? Here's a table that Wang and Wen came up with:

The left column shows the top-ranked human-created and human-voted memes for Chemistry Cat, Forever Alone, and Batman Slaps Robin. The middle column features the best automatically-generated memes using a less sophisticated method, and the right column has the best automatically-generated memes using Wang and Wen's method. We can see that Wang and Wen's computer manages to get a pretty good pun for Chemistry Cat and a decent Forever Alone reference, but fails at Batman Slaps Robin (Wang and Wen explain that it's actually a caption from the Overly Attached Girlfriend meme that just happens to mention "Batman" and "Robin"). But hey! That's still pretty impressive.

So, can a computer write a meme or are they uniquely human? So far, all we've really got is a machine that'll tell our own memes back to us.

Big Questions
What Does the Sergeant at Arms Do?

In 1981, shortly after Howard Liebengood was elected the 27th Sergeant at Arms of the United States Senate, he realized he had no idea how to address incoming president-elect Ronald Reagan on a visit. “The thought struck me that I didn't know what to call the President-elect,'' Liebengood told The New York Times in November of that year. ''Do you call him 'President-elect,' 'Governor,' or what?” (He went with “Sir.”)

It would not be the first—or last—time someone wondered what, exactly, a Sergeant at Arms (SAA) should be doing. Both the House and the Senate have their own Sergeant at Arms, and their visibility is highest during the State of the Union address. For Donald Trump’s State of the Union on January 30, the 40th Senate SAA, Frank Larkin, will escort the senators to the House Chamber, while the 36th House of Representatives SAA, Paul Irving, will introduce the president (“Mister [or Madam] Speaker, the President of the United States!”). But the job's responsibilities extend far beyond being an emcee.

The Sergeants at Arms are also their respective houses’ chief law enforcement officers. Obliging law enforcement duties means supervising their respective wings of the Capitol and making sure security is tight. The SAA has the authority to find and retrieve errant senators and representatives, to arrest or detain anyone causing disruptions (even for crimes such as bribing representatives), and to control who accesses chambers.

In a sense, they act as the government’s bouncers.

This is not a ceremonial task. In 1988, Senate SAA Henry Giugni led a posse of Capitol police to find, arrest, and corral Republicans missing for a Senate vote. One of them, Republican Senator Bob Packwood of Oregon, had to be carried to the Senate floor to break the filibustering over a vote on senatorial campaign finance reform.

While manhandling wayward politicians sounds fun, it’s more likely the SAAs will be spending their time on administrative tasks. As protocol officer, visits to Congress by the president or other dignitaries have to be coordinated and escorts provided; as executive officer, they provide assistance to their houses of Congress, with the Senate SAA assisting Senate offices with computers, furniture, mail processing, and other logistical support. The two SAAs also alternate serving as chairman of the Capitol Police board.

Perhaps a better question than asking what they do is pondering how they have time to do it all.

Big Questions
What Makes a Cat's Tail Puff Up When It's Scared?

Cats wear their emotions on their tails, not their sleeves. They tap their fluffy rear appendages during relaxing naps, thrash them while tense, and hold them stiff and aloft when they’re feeling aggressive, among other behaviors. And in some scary situations (like, say, being surprised by a cucumber), a cat’s tail will actually expand, puffing up to nearly twice its volume as its owner hisses, arches its back, and flattens its ears. What does a super-sized tail signify, and how does it occur naturally without help from hairspray?

Cats with puffed tails are “basically trying to make themselves look as big as possible, and that’s because they detect a threat in the environment," Dr. Mikel Delgado, a certified cat behavior consultant who studied animal behavior and human-pet relationships as a PhD student at the University of California, Berkeley, tells Mental Floss. The “threat” in question can be as major as an approaching dog or as minor as an unexpected noise. Even if a cat isn't technically in any real danger, it's still biologically wired to spring to the offensive at a moment’s notice, as it's "not quite at the top of the food chain,” Delgado says. And a big tail is reflexive feline body language for “I’m big and scary, and you wouldn't want to mess with me,” she adds.

A cat’s tail puffs when muscles in its skin (where the hair base is) contract in response to hormone signals from the stress/fight or flight system, or sympathetic nervous system. Occasionally, the hairs on a cat’s back will also puff up along with the tail. That said, not all cats swell up when a startling situation strikes. “I’ve seen some cats that seem unflappable, and they never get poofed up,” Delgado says. “My cats get puffed up pretty easily.”

In addition to cats, other animals also experience piloerection, as this phenomenon is technically called. For example, “some birds puff up when they're encountering an enemy or a threat,” Delgado says. “I think it is a universal response among animals to try to get themselves out of a [potentially dangerous] situation. Really, the idea is that you don't have to fight because if you fight, you might lose an ear or you might get an injury that could be fatal. For most animals, they’re trying to figure out how to scare another animal off without actually going fisticuffs.” In other words, hiss softly, but carry a big tail.
