Oh, man. President Obama had better remind Joe Biden that he's vice president now and not doing corny stand-up at Caroline's Comedy Club. Last week while swearing in the senior staff members, VP Biden made a joke about his memory not being as good as Chief Justice John Robert’s. (You remember him, the guy who flubbed the inaugural oath during Obama's swearing-in ceremony.) Whoops. Inappropriate. Jon Stewart, of course, is there to mock Biden, and to introduce us to a face I hope we don't see a lot of: Obama's STFU face. Eek!
