Video: Andrew Christian Underwear Dance-Off

It goes without saying that underwear designer Andrew Christian (from the Bravo reality program The Fashion Show) knows how to craft the perfect pair of sexy yet masculine briefs. But more importantly, he knows how to grab our attention and convince us to buy said underthings: with fun, energetic videos featuring smoking hot models in--you guessed it--their skivvies. His latest Internet short is set to the song "Punch That Booty," and features a roomful of beefy dudes romping around. Careful now, this video is on the PG-13 side, so you may just have to wait until your home to watch it.
