Remember, in 2013, when Obama was president, and Miley Cyrus released “Wrecking Ball,” and everybody—and I mean everybody—was doing the Harlem Shake?

The song shouts out “Con Los Terroristas,” and someone’s hips awkwardly gyrate to an ascending beat. Then, after about fifteen seconds, the beat drops, the video cuts, more people enter the frame and they collectively lose their minds. Dressed up in costumes, people flail and do what some might call dancing. After a short but sometimes unwatchable ten seconds of madness, it’s over.

If you were a person on the Internet at the time, odds are you watched the videos. You might have even made your own. Rewatching them now reaches ice-bucket-challenge-levels of cringeworthiness—but in 2013, we couldn’t get enough, and the videos have hundreds of millions of views to prove it.
