I'm trying to think of other ones. Oh, yeah, I'd say - somebody would buy something and we'd say, and because you are our hundredth customer today, you get a free paperback.

I always think back to my high school days and realize all the people who were so popular then are nowhere now and all the people who were steadfast and steady-going are somewhere. So high school doesn't necessarily translate to later in life.

I don't think anyone is ever writing so that you can throw it away. You're always writing it to be something. Later, you decide whether it'll ever see the light of day. But at the moment of its writing, it's always meant to be something. So, to me, there's no practicing; there's only editing and publishing or not publishing.

I think probably the most difficult challenge was just the climb and rise in show business because I went through my entire twenties with some success as a comedy writer but not much as a performer. And you have to be kind of informed and naive at the same time.

The lure in art collecting and its financial rewards, not counting for a moment its aesthetic, cultural and intellectual rewards, is like the trust in paper money: it makes no sense when you really think about it. New artistic images are so vulnerable to opinion that it wouldn't take much more than a whim for a small group of collectors to decide that a contemporary artist was not so wonderful anymore, was so last year.

I think there are people out there writing original bluegrass songs, but it's hard to get them out on the air.

Kids like my act because I'm wearing nose glasses. Adults like my act because there's a guy who thinks putting on nose glasses is funny.

I try not to think about legacy because it is all ­folly. If you study history, even recent history, you'll find many people who were quite significant in their time but are completely forgotten.

There is something going on now in Mexico that I happen to think is cruelty to animals. What I'm talking about, of course, is cat juggling.
