We didn't have rehab back in the Seventies. Back in the Seventies, rehab meant you stopped doing coke, but you kept smoking pot and drinking for a couple more weeks.

I studied acting in school and then of course couldn't get an acting job.

I needed someone really intense, but also somebody with a lot of theatrical credibility.

There are some guys I know for a fact, like Louis C.K., who always talk about how not-great of an actor he is, and he's terrific on his show. But I know Louis would play a fantastic dramatic role in something, too. He just needs somebody to grab him and say, "Come in here and do this."

The things that make me angry still make me angry. George Carlin is 67, and he's still as funny as he's ever been, and he's still angry. And that makes me feel good, because I feel like if I stick around long enough, I'll still be able to work.

I'm praying for 'Ice Age' 4, 5, 6, 7, 8, 9 and 10. Because I really think we can run those characters into the '60s, and I'm talking the 1960s, you know? The Civil Rights Movement. That's what I'm praying for, because then I wouldn't have to do anything else.

I've only done two other TV shows [instead of Sex&Drugs&Rock&Roll], one was Rescue Me and the other was a show called The Job, which was at ABC and only on for two seasons.
