I've always been very interested in ensemble work. One reason why I don't go out and do a stand-up act is that I did it once and I found it unsatisfying. I don't really like being out there by myself. I like reacting with other people.

I usually go in ahead of time, like at a rehearsal, or a meeting, and tell them, "It may appear that I'm going to go haywire, but I'm not." I always map out what I'm going to do. Still, a lot of it is improvised.

When I was about five my dad built a stage for me in our basement. A full stage, with a curtain, a backdrop and a dressing room. There were three colored spotlights - a red one, a white one, and a blue one. Blue was for nighttime scenes, and red was for when we were in hell. If the neighborhood kids wanted to use the stage, they had to incorporate me into the play.

I think the first time I was on The David Letterman Show, he didn't quite know what to expect. I think people generally are just a little afraid.

I can sit in the room with the other writers and just keep saying no until there's something I really like or until I come up with something. In that respect the proportion of what's mine and what's other people's is controlled by me. It isn't even fair to talk about.

Yeah, this is what I think was a quality of movies, is you're in a group of people. You're sharing something with people. Whether those other people make you laugh more, you're all laughing. You're all happy together. There's something... manmade about that in a way that's - I'm not sure how that manifests itself in nature, but culturally we've set that up when we invented theater and the movies and all that stuff.

I don't think Bruce Willis can compete with me. I have a much better voice.
