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

I looked at the job of piano accompanist. It's a selfless position and generally they are odd people, according to opera singers I talked to. Just like everybody else, they want more from their life, but now their job is to make others shine.

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.

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.

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 amazing to watch somebody who is kind of this sleazy, degenerate lothario, sex-crazed guy become sort of a romantic, settled-down man about to have a baby.

There are those moments where you realize that your parents or your heroes are human and are fallible. That concept, in and of itself, is something that is dangerous to me, in a good way. It's exciting and scary to meet those people.
