Tupac Shakur always wanted me to smoke weed with him, and I never did it, and I wish I did...That's my biggest regret.

I'm just like you. I enjoy the forbidden fruits in life, too.

I earned that the strong will always beat the weak, but the smart will beat the strong. Boxing is a tough guy sport. But in the end, the tough guy gets to clean the streets and be a bodyguard. In the ring, the tough guy is going to get hurt; at the end of the day, he's going to talk funny. Only the smartest win. So, I know it's cliché, but power - real power - comes from knowledge, comes from smarts.

What was most important was the knowledge [aspect] of the fight. I learned this early on and just told myself to "upgrade my mind." That's just what I wanted to do my whole life.

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 guess I'm going to fade into Bolivian.

I'm the best ever. I'm the most brutal and vicious, and most ruthless champion there's ever been. There's no one can stop me. Lennox is a conqueror? No, I'm Alexander, he's no Alexander. I'm the best ever! There's never been anybody as ruthless! I'm Sonny Liston, I'm Jack Dempsey. There's no one like me. I'm from their cloth. There's no one that can match me. My style is impetuous, my defense is impregnable, and I'm just ferocious. I want your heart! I want to eat his children! Praise be to Allah!
