I'm a huge Groucho fan. There were some great comic minds that would transfer into any generation, and Groucho is certainly one of them.

I'm afraid of heights. Not unreasonably, but rationally afraid of heights. I think everyone is.

I've been involved in mixed martial arts since 1997 when I first started working for the UFC.

If someone plays a brooding actor in a film, people think they're brooding all the time.

People for the most part can smell lies.

People want their 15 minutes and are willing to do anything to get it.

The audience changes every night. You're the same person. You have to speak your mind and do the stuff that you think is funny and makes you laugh.

The Comedy Store in LA, it's a really loose room and it's really dark and creepy and a great place to explore your own thoughts onstage.

The comics I hate are thieves. Nothing's more disgusting than a guy who steals another person's ideas and tries to claim them as his own.

To me, comedy is a great occupation because I don't really worry that much about what other people think of me.

When someone comes along and expresses him or herself as freely as they think, people flock to it. They enjoy it.

Your body's really only meant to compete at the highest levels of combat sports for a few years.

I had a great time on News Radio, I got to make tons of money in relative obscurity and learn a lot about the TV biz and work on my standup act constantly. It was a dream gig.

I had seen movies before that that had made me laugh, but I had never seen anything even remotely close to as funny as Richard Pryor was, just standing there talking.

I wouldn't totally rule out doing Letterman or the Tonight Show if I had a set that I just happened to write that I thought was funny but was still appropriate for network censors. But I'm not going to go out of my way.

I've done jiujitsu a huge chunk of my life, and I try to spend a lot of time educating people on the nuances, the subtleness of the ground game. It's a big part of mixed martial arts.

It never hurt Lenny Bruce's career to get arrested for swearing. It did back in the time, but he broke those doors down by doing the stuff that he believed in.

The misconception is that standup comics are always on. I don't know any really funny comics that are annoying and constantly trying to be funny all the time.

The planet's spinning a thousand miles an hour around this gigantic nuclear explosion while these people roll these machines with rubber tires over this hard surface that we've laid down over the planet so that we can easily move ourselves back and forth.

When you snatch little pieces of other people's lives and try to palm them off as your own, that's more disgusting than anything. Robin Williams is a huge thief. Denis Leary is a huge thief. His whole stand-up career is based on Bill Hicks, a brilliant guy who died years ago.
