Last week on David Letterman, Letterman asked David Arquette what he thought of this season’s Dancing With the Stars contestants.

But David had not a word to say about Chaz or Carslson and went right to the meat of the matter. Rob Kardasian’s and his amazing butt.

Said Arquette: “The thing about Rob is, and a lot of people don’t know this, but he’s got a great ass just like his sister…I’m serious! Once you see it, his ass is fantastic…And I really think it’s going to be a secret weapon.”

I think it is too. ASSWOW!
