I was a big Fred Flintstone fan.

I wrote on a show called Johnny Bravo when I was at Hanna-Barbera and he guest-starred as himself.

There are times when I'm under the weather and the corporate machine tries to put me in the recording booth anyway. It's always up to me to say, 'Guys, listen to me, listen to what I sound like. I'm not myself.'

The trend today is vampires, zombies, angels, all the stuff that puts me right to sleep. It's too bad because it's so much less interesting than the diversity of stories you can tell with science.

Sarah Palin is very pro-life of course, unless the life is that of an Iraqi civilian or a wolf running frantically from a roaring helicopter while being strafed with ribbons of automatic weapons fire.

I'm not a fatalist. I'm not a religious person. I'm sure there are close calls that we're not even aware of hundreds of times a year. You cross the street, and if you'd crossed the street two minutes later, you'd have been hit by a car, but you'd never know it. I'm sure that kind of stuff happens all the time.

Evolution doesn't care whether you believe in it or not, no more than gravity does. I want to rekindle excitement over what we've achieved as a species with the space program. We can't afford to regress back to the days of superstition.
