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.

Im married, so I tend not to hit on every girl.

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!'

Everybody has something now. It's become very over-saturated, and it's hard to weed out what's good, what you should watch and what you have time to watch. And Twitter was much less crowded, at the time, and it was an easier way to reach people. So, the combination of having a great video, a lot more access to people through Twitter, and having Kickstarter be this new thing in. We tapped into it, at its inception, and got people interested in it just based on the concept of what Kickstarter was. The timing was right.

It was like in the film, when I was actually doing a take and wasn't quite sure of the context, and then in the completed film it works beautifully.In the end I didn't know why I felt so shitty doing it, and why it turns out great in the final product. I guess you have to live in that unknown.

Generally people are nice, but it's so weird that it has made me more cautious. Just like anyone else, I like looking around at my environment, but now as I walk down the street I tend to look down.

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.
