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 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."

I think my entire career path was determined for me when I was 6 years old, watching reruns of 'I Love Lucy' on TV and thinking about making people laugh.

I've always felt like a kid, and I still feel like a kid, and I've never had any problem tapping into my childhood, and my kid side. And I think that's a very universal thing, I don't think it's unique to me at all. People I've talked to in their 60s, 70s, 80s, and 90s have all told me "You know, I still feel 20." So I don't expect that I'm going to be any different.

Part of what I do comes from the fact that I don't know any jokes to tell. And when I do they're really flat and don't work.

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 know you are, but what am I?
