Everybody you fight is not your enemy and everybody who helps you is not your friend.

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.

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.

Every punch was thrown with bad intentions.

No one wants to get up at 4 and run when it's pitch-dark, but it has to be done. The only reason i do it so early is because i believe the other guy isn't doing it and that gives me a little edge

I probably have a 20,000-word vocabulary. I'll match my wits with anyone on literature, science and the arts.

I'm scared every time I go into the ring, but it's how you handle it. What you have to do is plant your feet, bite down on your mouthpiece and say, 'Let's go.'
