When you're a great finisher, you'll become popular. Joe Louis was a great finisher.

Anger is my biggest enemy in life.

I am the most ruthless, brutal champion ever. There is no one who can match me. I want your heart. I want to eat your children.

I had to persevere because this was my life. This championship, this was the stuff I dreamt of all my life, and I wasn't gonna be denied.

You think the speed of your fingers can match the strength of my fists?

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.

When I go to Europe or South America, they laugh at things that are totally different than what Americans would laugh at. It's just so crazy how we're so different in personalities with other people.
