Harlem Shake? Turn Off The Internet.

The Harlem Shake meme involves 30-second videos that begin with a sole person, typically masked, casually bopping to music while a handful of people around him go about mundane business. Then “the beat drops,” as the kids say, the camera shot changes, and suddenly an entire crowd appears in bizarre costumes and they go crazy, flailing their limps, and, well, doing the Harlem Shake.

What the heck is this? What's so funny? 

And proof that it is not cool because The Today Show has done it.
