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 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 wasn't a great improviser when I started there; I'm not really up on current events. I would always just mug, just try to get my laughs from making faces. So I decided to do a character who should never have become a comic - somebody you would see at the Comedy Store and go, "This person is never going to make it."
