When people are tipsy, they're really encouraged and they wanna prove they can do something to the Heavyweight champion.

Defeat will help you. I've been there and done that. I shook it off and came back stronger. It's nothing to be scared about.

There are 49 guys that got bored to sleep on my record, so they got knocked out by it.

All the champions - you go and ask Mike Tyson or Joe Louis, Rocky Marciano, Lennox Lewis and myself included, and I'm sorry for putting myself in line with all the other great names - but the champion's attitude is it doesn't matter who is in front of me, I am going to conquer this person and win the fight and knock the person out.

I know he's retired, but I'm a big fan of Shaquille O'Neal, his game and his personality. I have a pair of his shoes in my office. You see the size of his shoe and think, 'This is not real, this couldn't belong to a human being.' But he is human!

Sometimes it's boring because it takes time, but it's enjoyable. So beating up people for a living is really fun.

Aggression means emotions. Emotions means you’re gonna get off your plan and that means you’ll lose the fight.
