I was blessed with speed and a good punch. Everybody thinks I'm the hardest puncher ever. But I just think I was really fast, and my punches got to the target faster. That's what made my knockouts always seem spectacular.

I never think of physical fighting. It's always spiritual. Fighting is spiritual.

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.

When I fight someone, I want to break his will. I want to take his manhood. I want to rip out his heart and show it to him.

My power is discombobulatingly devastating. It's ludricrous these mortals even attempt to enter my realm.

One minute I'm robbing a dope house. Next minute I'm the youngest heavyweight champion of the world. I'm only 20, 19, with a lot of money. Who am I? What am I? I don't even know who I am. I'm just a dumb child who's being abused and robbed by lawyers. I'm just a dumb pugnacious fool. I'm just a fool who thinks he's someone. Then you tell me I should be responsible.

I just don't have the desire no more, I don't have the stomach to do it no more. I don't even kill insects in my house. I just don't kill anything no more. I used to kill pigeons, rip their heads off, 'You dirty rat pigeon!' I don't even have the heart to kill an animal no more. I just changed my whole life in general. That probably could have changed the way I fight.
