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.

If I had any dignity, that would have been humiliating.

I would have to say that looked like it hurt.

Mostly I make lists for projects. This can be daunting. Breaking something big into its constituent parts will help you organize your thoughts, but it can also force you to confront the depth of your ignorance and the hugeness of the task. That's OK. The project may be the lion, but the list is your whip.

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.

Let's get on our knees and pray. I don't know to whom. Is there a patron saint of ballistics gel?

My dignity and good television - they'll never meet.
