I had to learn all the pieces backward and forward [to play it in "Florence Foster Jenkins"]. We practiced on weekends. It was very much like being in school, except it was with Meryl Streep. Like, I would go to her apartment and we would practice Mozart's "Queen of the Night."

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

I don't mind being recognized, it's just that I have a bit of social anxiety, and this situation has increased it. The idea of having to be 'on' and social at random times can be difficult. I'll be out in the morning, someone comes and takes a picture, and then I discover I have toothpaste on my face.

I wanted to come to Chicago. I also wanted to do "Saturday Night Live." And then I got to a place where I didn't want to do those things anymore.For the sketch comedy thing, I got cast on "MADtv," and that will kill any man's desire to do comedy.

I was like, I can't believe I get to be in a scene with Meryl Streep [in Florence Foster Jenkins]! And then I was like, but why do I have to play Chopin? It's already going to be intimidating.

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 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.
