That is what's disconcerting about working on the show, you can't seem to get an instinct about what works and what doesn't. It happens a lot, and in different ways.

I met a bunch of people and they said, "We're gonna do a show [Second City]." So we would buy the theater out and do a show, and we did that for five years and we ended up becoming popular. It was before sketch comedy was hipster-time - when you would hand out a flier, people would roll their eyes. Now it's kind of cool.

The weird part is actually, there were so many exceptionally talented people there [ on "MADtv"]. But it was a disaster. I don't think I enjoyed any of it, really. I had a different sensibility.

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.

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.

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!'

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.
