I think I might've turned 39, look like I turned 29, feel like I turned about 19.

Boxing is not brutal, it's an art - God has gifted me with incredible handspeed as a tool to be used - what else am I supposed to do but fight? There ain't no hand-racing competitions.

I'm having a wonderful time in training. It's so funny because you go through ups and you go through downs. People have to realize that my career started on a down. I got ripped off a Gold Medal at the Olympics but it didn't stop me and it made me a better person.

Charity work shouldn't be bragged about. It's just something you're supposed to do...I do it because I feel like that's what God wanted me to do. It's as simple as that.

I got some real rough dental work done not long ago, and my mouth's still numb right here [points to the left side of his chin]. So it kind of messes with my speech a little bit, so don't y'all think that I took too many cos I haven't.

We're in Madison Square Garden, I can't let you beat me in Madison Square Garden, are you serious!?

Boxing’s an art, it’s a science, and you don’t go out to knock people out. If they happen to get knocked out, they happen to run into one of these bricks by mistake [looks at his fists], that’s their fault.
