I always bring out the best in men I fight, but Joe Frazier, I'll tell the world right now, brings out the best in me. I'm gonna tell ya, that's one helluva man, and God bless him

Every time I look in the mirror, I see that kid from Louisville, Kentucky, staring back at me. His name was Cassius Clay.

God gave me this illness to remind me that I'm not Number One; He is.

I'm pretty as a girl.

I don't always know what I'm talking about, but I know I'm right.

If my fans think I can do everything I say I can do, then they're crazier than I am. After one of his fight predictions turned out to be wrong.

Will be a divine fight, a holy war...Armageddon on a miniature scale.
