If you did everything your mind told you to do, you do some really strange stuff. You'll probably be in jail, you'll be in trouble. But, it's all about control. We all have to control our feelings. That's the thing that separates us from animals.

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.

My objective is to destroy anybody over 200 pounds, in the ring or out.

I paid a worker at New York's zoo to re-open it just for me and Robin (his wife). When we got to the gorilla cage there was 1 big Silverback gorilla there just bullying all the other gorillas. They were so powerful but their eyes were like an innocent infant. I offered the attendant $10,000 to open the cage and let smash that silverback's snotbox! He declined.

I'm going to gut you like a fish.

I don't want my kids to be like me, I don't want my daughter to date a guy like me. You know, for a guy like me success is to take care of my children to take care of their life and make 'em cushioned. I don't want them to be around people like me. You know, success for me would be that they never have the opportunity of being in the presence of someone like me.

Everyone says "I wish I was in your shoes...", the hundreds of people that wish they were in my shoes don't know the tenth of it. If they were in my shoes they would cry like a baby.
