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

Bill Prady and Chuck Lorre, the guys who run that show [Big Bang Theory], are really funny and really smart, and the cast is fantastic to work with.

Initially I objected to the Data makeup. I said, "Why do I need this makeup? Why can't I just look like me?" In fact, I said to Gene Roddenberry, "Don't you think that by this time in history, they would've figured out how to make skin look like skin?" And he said, "What makes you think that what you have isn't better than skin?" And I went, "Um, okay."

As I get older and I get more of this dialogue and I lose more and more brain cells, it really does become the most difficult part of the job!

As it turns out, sometimes that bites you. In this case, I saw pictures of Earl [Mills], and...I actually met him. He was quite old at the time, but he had this sort of curly red hair, so we did that in the film. I got a perm and had red hair, and... It was a mess.

I assumed, "Well, I must've sounded like Conan O'Brien, or a reasonable facsimile or something." And there I am in the movie [South Park: Bigger, Longer & Uncut ]. I was very lucky.

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.
