What I wanted to do was music, until I was about 16. But it was jazz and rock, never classical music.

It's not really about confidence. It's just something that isn't really in the vocabulary of what goes on at work. The writers write and the actors act.

There's also these moments when you're like, oh, I really want to do different things. Not instead of this show [The Big Bang Theory]. It's just a hunger to do something else, too.

There are bits at the table read that destroy, so much so that we can't wait to do it in taping. And then, no reaction. And then there are times when I can't get the right read on a line in rehearsal, and then the audience howls at it. The strange thing is I still don't know why it happens like that. It's not like afterwards I think, 'Now I know why that worked!'

It's always nice when someone says that they don't realize it's me on screen, but it would be strange to enter a one story while thinking of another character I do, which is completely different.

The weird part is actually, there were so many exceptionally talented people there [ on "MADtv"]. But it was a disaster. I don't think I enjoyed any of it, really. I had a different sensibility.

I wouldn't wear turtlenecks. That I'm not envious of. But who knows? I might sneak out a few things and hope and pray that no one says, 'Hey, didn't you wear that when you were playing an enormous geek on TV?'
