I enjoyed this conversation between Jerry Seinfeld and David Letterman. It's Dave interviewing Jerry about the latter's Comedians in Cars Getting Coffee series. What struck me is that Dave actually seems to be enjoying the conversation. I don't think anything drove me away from his talk show more than the sense that he was bored with most of his guests.
He mentions in the interview that he's looking for a job. I'd sure like to see him do a weekly hour where he just chats with someone he finds interesting.
