We're constantly re-evaluating the potential for life. We're finding it where we didn't think it could exist, such as volcanic vents and other extreme conditions like under arctic ice. We're finding life in these incredibly harsh and dynamic conditions, so we're having to re-evaluate our own ideas of what's possible on this planet alone.

As a longtime practitioner of yoga and a person who's been involved in physical fitness my whole life, I can tell you, yoga helps you achieve altered states of consciousness. It is not just stretching. The only way you can say that it's stretching is if you haven't done it, or that you haven't done it rigorously for a long period of time.

You do what you're supposed to do, but you have to be honest about what they're doing. When you do a comedy show on a network the problem is there are going to be a bunch of people who aren't comedians that are going to tell you what's funny.

I brought something back from those experiences [with drugs] which made me softer, open to other ideas. And I've learned from listening to other people talk about their experiences, from listening to Bill Hicks or reading Terrence McKenna or Aldous Huxley and Timothy Leary. But there's always some dumb cop out there who says "We don't need another legal drug and there's psychological addiction and blah blah blah."

I don't care if you're gay, black, Chinese, straight. That means nothing to me. It's all an illusion.
