[Trey Parker and Matt Stone]called me one Saturday morning and said, "Can you do an impression of Conan O'Brien?" And I said, "I don't know." Because that was really... He hadn't been on the air that long, and to be honest, I hadn't watched much of him at that point. So I went to Santa Monica to their studio and said, "Well, what does he sound like?" They said, "Well, just try it one time. Read the copy." And I read the copy one time, and they went, "Okay, that's fine. Thanks a lot, that'll do. That's perfect."

Joey being one of my finest performances ever. Matt LeBlanc's basically doing the same thing right now, playing himself on Episodes. When I did Joey, I really leaned on them to make me the biggest ass they possibly could, because, frankly, everyone in their heart of hearts thinks of themselves that way. Or at least I do, anyway.

John Logan was kind of wrapping up - "Well, thanks for coming in..." - and I thought, "Oh, God, this is over and I'm out of here, and I really don't want to leave."So I said, "Can I ask you a question?" He said, "Sure." "What movie do you think you've seen more than any other movie?" And he said, "Wow, let me think about that. I guess probably The Searchers." And I said, "Well, oddly, that's the movie I've seen more than any other movie." And I wasn't just BS-ing. It's true. It's my favorite movie.

I know a guy who writes on the show, it was his episode, and he called and said, "Would you do it?" And I said, "Yeah." There's not really much else to tell, except that I was thrilled to be on The Simpsons, because it's one of the greatest series in the history of television.

Pierre [from Dude, Where's My Car?] could be the best thing I've ever done. When you distill it down to a minute and a half of work, that may be my finest effort.

Radical surgery is never fun.

I think we're all fans, and I understand the whole world of fandom, because I am a fan.
