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.

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

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 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."

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.

Actually, when I was young, I believe I met Nicolas Cage. I think I was probably eight, and I remember seeing him at somebody's house - it was an event and he happened to be there. People would ask me if I was his son, because I looked like him at that point, so I do remember feeling some connection and just wanting to say, like, 'Papa!'

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?'
