David Berg served as producer for "The Tonight Show with Jay Leno" during its entire run.  He just wrote a book called, "Behind the Curtain:  An Insider View of Jay Leno's Tonight Show,"  and it in he shares some behind the scenes celebrity dirt.  Here are the top revelations from the book -

 

1.  Christian Bale was a very difficult guest and got into arguments about potential "personal" questions like - "Where did you grow up?" and "What was your first acting gig?"

2.  The show had a bar installed backstage to help guests relax.  Quentin Tarantino once drank so much at the bar that he wound up slurring his words.

3.  Dennis Rodman had such a problem with being late they wound up having to send a helicopter to get him.

4.  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 Lewinsky jokes.

5.  The show once bumped Benjamin Bratt for a segment with an animal trainer because they knew it would do better ratings. Bratt boycotted the show from then on.
