Every time I think about writing, comedy doesn't interest me in the slightest. I can play comedy, but I don't think in terms of comic dialogue.

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.

I don't think the jet-setting life is really for most people.

It's a shame, but every time I get something scientific in the script, I read up to find out what I'm talking about - but then I'm on to the next script and it's forgotten.

What this is about is hopefully an opportunity for me to help pave the way for my future in terms of getting financially choosier. You have to plan the windfall as if it'll be your only one.

I've always loved TV very much, and as a child I was so religious with it, but now it's more when it fits in.
