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.

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!'

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.

I wanted to move on. I wanted to do acting. The next thing I did after [MADtv] was a good hybrid of that. I did this show with Bob Odenkirk and Derek Waters (creator of Comedy Central's "Drunk History") and it was a little homegrown thing that we shot and then we sold it to HBO. We made a pilot and HBO didn't pick it up, but then we made all these webisodes. This was before streaming stuff online made any sense. (The episodes are available on YouTube). Nobody even knew how to watch things on the internet.

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 did not want to be the accompanist to an operatic star. But I was at a very high level for a 16-year-old, and I maintained that. So really good, but more impressive than classically trained. So I had to take a crash course in classical technique because I really wanted to get away with playing this character [in Florence Foster Jenkins] without people saying, "That's not really accurate."

I came in ["MADtv"] kind of late in the season. Some of the producers didn't want me but the network did. It was all (messed up) from the beginning.
