Five Things You Need to Make Your Own "Harlem Shake" Video
3. Humping. Lots of humping.
Since we mentioned humping twice already, it's pretty damned obvious that it's an essential element of the "Harlem Shake" video. Make it vigorous, hump everything, anything -- chairs, animals, the wall, your friend, your friend's grandpa, whatever.
2. At least 50 people for when the beat drops.
The more people other than the actual starting dancer, the more impressive the video. And if those people use props, even better. For the best, though, include Pepe Billete, and call it the "Haslem Shake."
