It does seem like the Harlem Shake is the next big thing hitting YouTube and the Internet in general. It's gone viral pretty quickly and it seems like everyone is doing it now. I don't think it'll be around too long, though, as just like Gangnam Style, it'll probably be replaced with something new that goes viral. That always seems to happen, anyways. I have to admit that I do enjoy watching people dance to the Harlem Shake song, though, but it is kinda getting old already. I say it'll last another month or two before it's substituted by a new Internet hit!
