Quentin Tarantino drank so much at the bar when he was a guest in 2003 that he wound up slurring his words and was incoherent on the show.Dennis Rodman made 28 appearances on the show and had such a problem with being late they wound up having to send a helicopter to get him.The show tried to bribe Bill Clinton to come on and sent him a $12,000 custom-made bike.
