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!'

When you have this long of a run [in The Big Bang Theory], you don't have to have something happen every episode. Like, Sheldon lost his virginity last season and in the first season he didn't even like girls. So I feel like you can earn that stuff. And that is really fun, because you get to find new layers. It's a testament to the writing.

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.

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.

I came in ["MADtv"] kind of late in the season. Some of the producers didn't want me but the network did. It was all (messed up) from the beginning.

Well, I think that everybody is kind of a nerd at heart.

I actually struggled through teaching myself to cook because I'm completely ignorant in the kitchen. So I did really macho things like trying to make my own curry. Really hardcore stuff.
