We estimate that there are perhaps 20,000 prehistoric hunter-gatherers frozen up in those glaciers. Now, if they simply thaw and wander around, it's not a problem, but if they find a leader - a Captain Caveman, if you will - we'll be facing an even more serious problem.

Even in my own life, there are memories I have that are difficult to explain - happenings that are so odd and unaccountably weird, that it is difficult to imagine they were not the result of prolonged and frequent contact with aliens throughout my life.

As a live stand-up comedy performer, I have the benefit of choosing real entrance music.

The nice thing about live performance is that I've never, ever been let down. Partly I'm lucky that my audience self-selects itself. Generally they know what they're in for, and generally we all just like each other and get along. But I always find one or two or a dozen really interesting people in the audience who make the show different. And that's one of the things I really like about performing.

Only the nerds will save the earth.

I think in American culture, we put value on economic success but tell people you don't have to be economically successful to be happy.

My fame is due to broadcast television.
