To me the ambiguity is, maybe our perception of ourselves is always going to be different than somebody else's perception. There will always be that disparity.

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?'

I always honestly dreamed of coming to Second City in Chicago, although I've never even been there to see a show. But I did a ton of sketch comedy at the Second City in LA, which (at the time, in a different location) wasn't really a theater, it was just a space where you took some classes.

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.

I was young. I was 23 or 24. I just wasn't a fan of the politics of campaigning - of going into that environment and competing and trying to get into the good graces of the writers.

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.

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.
