The quickest way to defuse fear or insecurity or anger is usually humor. I think comics figure that out quickly, and, once you figure it out, you think, 'Hey, if I can do this and get paid, that would be kind of cool.'
Comedy is much more difficult than tragedy-and a much better training, I think. It's much easier to make people cry than to make them laugh.
I don't sleep much. It takes me a long time to fall asleep. I'm a bit of an insomniac but, when I fall asleep, I don't ever want to wake up.
