Well Stephen Colbert made 2 Beatle references recently. In one he was calling someone a 5th Beatle (about somebody who really didnt have anything to with them) I think it went "whom I'll always remember as the 5th Beatle" and another where he said "The only way to make money in today's economy is to divorce Paul McCartney"
"You should have thought of that before we left the house"
