That Harlem Shake thing is really catching on. We hope it's the next 'Gangnam Style,' although that's mostly because these videos are only 30 seconds long. This version of the Harlem Shake features actual firemen in a fire truck. The thing we're left wondering though is why do so many people own full body costumes, and how are we in the part of the population that doesn't. Fortunately, this is a problem that is easily solved.
