That depends on whether you’re talking about the Harlem Shake dance, the Harlem Shake song, or the Harlem Shake video — by either Al B, Albee, Baauer, Bauer, Bauuer, or the Russian Army. And, the infectious internet meme doesn’t get any less complicated from there. But since the original Sunlight Harlem Shake, it has gone viral on YouTube (or uTube if you prefer) at breathtaking speed.
