When McKayla Maroney teaches you how to "Dougie" you get your ass up off that double-decker bus seat and listen to the woman. That means your ass, Jenna Bush. On your feet! Watch a pro and learn something instead of lobbing fluff questions to the women's gymnastics team. Maroney might only be 16, but she'll teach your conservative ass a few things in London. And teen boys just found a new hero. JUMP!
