If you're unfamiliar with this Internet meme, here's some background via Wikipedia:
The art form of the meme was established in a video uploaded on February 2 by The Sunny Coast Skate, five teenagers from Queensland, Australia. The teenagers' video, in its turn, was a follow-up to a video by a YouTube comedy vlogger named Filthy Frank. featuring a part where several costumed persons danced to the song "Harlem Shake" by Baauer.
There's also a running list of videos on DavisWiki.
