Growing up in New York, I was sort of shocked when I realized that my children are Californians. They are 14 years old, and I explain to them frequently that they will never realize the glory of a snow day. You wake up and the world says, 'Oops, it's too much fun to go to school, you've got to stay home and deal with the snow!'

Audiences of critical thinkers are my favorite kinds of audiences. There are jokes I tell in the show that don't get laughs unless I am in front of an audience of critical thinkers. Put me in front of a crowd of science teachers or astronauts! The guileless aren't our audience - it's the critical thinkers we love.

We didn't set out to be educators or even scientists, and we don't purport that what we do is real science but we're demonstrating a methodology by which one can engage and satisfy your curiosity.

Being a geek is all about learning the inventories of things.

Often when you are starting out in comedy, you will find that people will laugh at the things you didn't think were funny. It's important to pay attention also to what people are laughing at when you are just talking in regular conversation. Often that is when you are truly being yourself.

In all my content I don't really swear or use profanity, because I believe comedy can just be pure.

The hardest part of comedy is writing the jokes, and the second-hardest part is telling the jokes. To me, everything else is significantly easier.

Comedy is the hardest thing to get right. I remember a joke we did in 'What's Up, Doc?' that didn't get a single laugh. So we moved the shot a foot-and-a-half to one side, and all of a sudden, the laugh was there. It drives you crazy; the balance is so delicate.
