My toughest fight was with my first wife.

It will be a killer, and a chiller, and a thriller, when I get the gorilla in Manila.

Never put your money against Cassius Clay, for you will never have a lucky day.

God tries you in certain, certain ways. Some people are rich, and they believe in God. They lose the money, things get hard, they get weak and quit going to church. Quit serving God like they did.

I calculate that I took 20,000 punches, but I earned millions and kept a lot of it. I may talk slow, but my mind is OK.

Joe Frazier is so ugly that when he cries, the tears turn around and go down the back of his head.

I'll beat him so bad he'll need a shoehorn to put his hat on.

I said I was 'The Greatest,' I never said I was the smartest!

Cassius Clay is a name that white people gave to my slave master. Now that I am free, that I don't belong anymore to anyone, that I'm not a slave anymore, I gave back their white name, and I chose a beautiful African one.

The fact is, I was never too bright in school. I ain't ashamed of it, though. I mean, how much do school principals make a month?

I should be a postage stamp, because that's the only way I'll ever get licked. I'm beautiful. I'm fast. I'm so mean I make medicine sick. I can't possibly be beat.

People don't realize what they had till it's gone. Like President Kennedy, there was no one like him, the Beatles, and my man Elvis Presley. I was the Elvis of boxing.

No one knows what to say in the loser's locker room.

Anywhere I go, there is always an incredible crowd that follows me. In Rome, as I land at the airport, even the men kiss me. I love Rome.

I am the astronaut of boxing. Joe Louis and Dempsey were just jet pilots. I'm in a world of my own.

I had to prove you could be a new kind of black man. I had to show the world.

To be able to give away riches is mandatory if you wish to possess them. This is the only way that you will be truly rich.
