Randy Jackson’s reign of terror, for this season anyway, is finally over as the winner of “America’s Best Dance Crew” was named last night in the final episode on MTV that kind of reminded us of those ESPN cheerleading championships, but with far baggier clothing. The winners: Las Vegas’ Super Crew. A swell bunch of multi-cultural teens who we’re sure can lindy hop like nobody’s business. In this clip of their victory dance, though, they decide to just crunk out or whatever the kids are calling it these days. Can we take a nap now?
