If Mike Tyson is in your courtroom and you don't send him to jail, it's an injustice. Everyone knows he's a bad guy. So if he is in your courtroom, he should go to jail.

I'm a historian, and that freaks me out.

I am not a role model.

The tempt for greatness is the biggest drug in the world.

Emotion is more than just anger. When I am performing, I need emotion, but I need control, too. Emotion drives the best performance and is necessary, but it must be controlled. I believe Fedor [Emelianenko] does that. I do too. We may look different in how we do it, but we both do it.

I'm in trouble because I'm normal and slightly arrogant. A lot of people don't like themselves and I happen to be totally in love with myself.

I want to throw down your kid and stomp on his testicles, and then you will know what it is like to experience waking up everyday as me. And only then will you feel my pain.
