Dances change all the time! And once a new dance breaks out then everyone once to do it. The Harlem shake is the newest dance craze out. I don't get what's the big deal, but it's funny to see other people dance to the Harlem shake. If you can't dance, it doesn't matter just do random things. This is the Simpsons Harlem shake called the "Homer" Shake! Check it out!
