I'm also a big American Idol fan. I think it's just great fun.

I did have a Twitter account that I tried for a couple days, but found I had nothing to say. There are some interesting facts I could share, but I don't want to share that part of myself.

Realistically, there is a danger, of course, when you're going into someone's living room as the same guy every week. But I don't fear it because, I mean, there's really nothing I can do about it. I can try to combat it through the work, and maybe make sure I don't do Sheldon 2.0 in any other projects. But it's just really hard for me to find any negative side effects from this experience.

As a human being, you know that there are some days when you'd rather not talk to anybody - but I can't really do that anymore without appearing rude.

In voicing so much is left to your imagination to create the world around you like that. It's really the essence of what's so fun for, I think, many people when they first start to want to be an actor, is that they realise they enjoy making up a world around them to exist in, a whole situation and a whole way of being. And even more so than theatre, animation requires that because there's just nothing to go on. It's in your head and your heart or it's not there at all.

Playing Sheldon is just heaven for me. I realize how enormously lucky I am to play a role that makes me so incredibly happy. As I told Chuck Lorre in a Christmas card a few years ago, I'm living a version of the dream.

Home is where you feel unjudged, and where what I do isn't necessarily stupid or wrong.
