I recently did the David Letterman Show about my book. He was very serious and made no jokes and it caught me off guard a little bit. He was much more serious than some of the joke shows that journalists get on. ↗
I have a great career, and no matter what I am doing, a big blockbuster movie... or my small documentary, David Letterman will call and say I would like you to sit on my couch. ↗
I wouldn't totally rule out doing Letterman or the Tonight Show if I had a set that I just happened to write that I thought was funny but was still appropriate for network censors. But I'm not going to go out of my way. ↗
