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.

There's no real escape from the work, but in some ways, if you're as obsessive as I am, it's a sweet little thing we've figured out. You bring your work home and you work 24 hours a day, but it's good.

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!'

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.

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.

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!'

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.
