It seems like everyone is uploading videos of their interpretation of the frenetic dance to YouTube, and Rockland is no exception.
This weekend members of CrossFit Rockland posted a Harlem Shake video they filmed together at the gym.
In all, there are more than 200,000 Harlem Shake videos on YouTube. They all begin the same way. As one person in a mask or helmet dances to the song of the same name, everyone else seems oblivious to what is taking place. But once the song commands everyone to "do the Harlem Shake," the video cuts to a large group of people in masks or costumes dancing wildly.
