People tell me I'm a comedian, but I don't approach acting from that perspective. I do know that everything in life has to do with your timing and perception. You have to be comfortable with the rhythm that you're in. You can't just jump into a fast rhythm if yours is slow. You might have to pick up the pace but in your own particular way. It has to do with personality, too.

Anyone with a grain of sense would know that if I punched my wife I would rip her head off. It's all lies. I have never laid a finger on her.

It's interesting that you put me in the league with those illustrious fighters [Muhammad Ali, Joe Louis, Jack Johnson], but I've proved since my career I've surpassed them as far my popularity. I'm the biggest fighter in the history of the sport. If you don't believe it, check the cash register.

Fear is your best friend or your worst enemy. It's like fire. If you can control it, it can cook for you; it can heat your house. If you can't control it, it will burn everything around you and destroy you. If you can control your fear, it makes you more alert, like a deer coming across the lawn.

No one who isn't an extremist can understand the mind of an extremist.

A man that is a friend to everyone is an enemy to himself.

I want to rip out his heart and feed it to Lennox Lewis. I want to kill people. I want to rip their stomachs out and eat their children.
