Timing is everything, as you know.

I have to say, though, that somebody pointed out to me on YouTube that Conan O'Brien was being interviewed, and he was talking about how, oddly enough, he went to see that movie [South Park: Bigger, Longer & Uncut ] in Hawaii with his girlfriend or wife or whoever, and he didn't even realize his character was in it. But there he was, and he said, "This voice comes out of me, and I'm thinking, 'That's not me! Who is that? That doesn't even sound like me!'

I mean, I'm the tag of the [ Big Bang Theory ] show! That was one of the easiest jobs I've ever had.

I wanted to look right. I remember a review - a very positive one - in The New York Times that said I was so good in the role [Earl Mills] that I "even managed to overcome a terrible red wig." I wanted to write her and tell her about the agony I'd gone through with the perm, but I thought better of it.

I can tell you one other story about Rent Control. The lead actress in the film, her name was Elizabeth Stack, and it turned out she was Robert Stack's daughter. The only problem with that - and she was lovely - was that she was basically hired because [Gian Luigi Polidoro] thought she was [film producer] Ray Stark's daughter. And he figured that if he ran out of money, her father would kick in some more. I can still remember the day he freaked out when he realized she was actually Robert Stack's daughter. He was just screaming "Untouchables!" over and over.

The character of Brent Spiner. We certainly collaborate on the concept of that, but he basically writes the script, then it's sort of a combination of his voice and my voice.

I've gotten such good feedback from that [re-team with Wil Wheaton for Big Bang Theory appearance], and I hardly did anything.
