Internet memes are mostly terrible, usually because they require a shockingly small amount of creativity and they become so mainstream that it's impossible not to get beat over the head with it.
The Harlem Shake is basically just that.
If you're unfamiliar with the latest dance craze that is sweeping the web, it's real simple: Someone starts dancing to the sound of the song "The Harlem Shake" by Baauer and about 15 seconds later, a large group of people suddenly start wildly dancing along with it.
That's it. Really.
I won't riff on how this is the end of society as we know it, although I'm tempted, but I will take the SEO points thanks to the folks at TNA getting on the action at a recent house show in Morgantown, West Virginia.
