Shooting this show is pretty intense. You lose your life. But I have no life, so it's perfect!

It's really cool to know that you've put something together that isn't for a particular audience. It's so often that a TV show can really only speak to one sect of the population, and this really is something that appeals to a worldwide fan base. People who are into the pursuit of knowledge. Their reaction has meant the world to us.

That's pretty much why I went into show business because I wanted to have a guitar and sing unaccompanied, that was like my fantasy of the perfect life.

So many shows out there dumb-down the country. It's so admirable to be part of a show that wants people to think.

Charlie's not your conventional mathematician... we sexed him up a little bit.

In your imagination, you can perfect things in a way you can't do in your everyday life.
