Letterman last night said that Howard Dean said he'll go back to being a doctor should he lose his bid for the nomination. Letterman asked whether anyone would really want to be his first patient. But so much further the joke could have gone. I really wouldn't want to be Howard Dean's patient: "First I'm going to look in your nose; then I'm gonna look in your ears; then I'm gonna look down your throat; and then I'm gonna **stick this tube all the way into your colon**. Yeaaaaaaaagh!" Or at least that's how I would have written the joke.
