Well, sanity, I suppose, is getting people to see the world your way.

I looked at longevity in show business when I was about 13, and the people who seemed to have longevity were the ones who'd spent quite a bit of time learning about what they were doing before they made it.

In fact, I don't watch a lot of contemporary comedy for fear of being influenced by it.

If you stay in a house and you go to the bathroom and there is no toilet paper, you can always slide down the banisters. Don't tell me you haven't done it.

It was a bizarre existence I led in my early twenties - that cliche of the comedian who goes out and entertains a roomful of people and then goes home to a lonely bedsit was unbelievably poignant for me because that was exactly what I was doing. I had periods of real loneliness.

Have you ever had sex with a horse?

I remember being fascinated by the very nature of comedy from the age of 10; why is this funny, and that isn't?
