Don't do it! Stay away from your potential. You'll mess it up, it's potential, leave it. Anyway, it's like your bank balance - you always have a lot less than you think.

If you're a comic, you don't have a rehearsal room; you rehearse on stage. My main concern is remembering everything. I've written lots of material, but how do you memorise 90 minutes? That's one hell of a long speech. I've always had problems with that.

You try various things when you're growing up. I was an attache in the Foreign Service for a while and then I drove a bulldozer, but neither of those panned out for me so it had to be stand-up.

I get a phone call once every 18 months from some mad person who wants me to do something for less than no money and they give me about a week's notice. That's my film career, most of the time.

I do think it's perfectly natural and human to want to invest belief in something. It's just a facet of who we are. What do I believe in? I believe in the obvious things. The people I'm close to and my work - it's not complicated.

You've a very important, early decision to make in your life: are you going to be alone, or are you going to be with somebody else? Are you going to be sane, or not lonely? A couple is a strange thing; it's an organism that's half as intelligent as the most intelligent member. And you both know who it is!

I have no qualifications to do anything else and there weren't any formal application forms you had to fill in for stand-up, so I thought I'd give that a twist.
