Christian Bale was a very difficult guest and got into arguments about potential "personal" questions that don't seem very personal at ALL like "Where did you grow up?" and "What was your first acting gig?"The show had a bar installed backstage to help guests relax. 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. He accepted the gift but still wouldn't come on the show because he resented all of the Monica Lewinsky jokes.
