Boxing has rules. Politics has very flexible rules.

When I see how far we came from in 1984, when for the very first time, I competed in an event that was not allowed for women, which is the 400m hurdles, and all of a sudden now we see women running marathons like men, competing in boxing, in wrestling …we will witness a fantastic summer Olympic Games in Paris.

Ain't no reason for me to kill nobody in the ring, unless they deserve it.

To the greatest fans and the greatest sport in the world, thank you! Thank you for all the wonderful memories. This is the hardest decision I’ve ever made, but I’m at peace with it. Chase your dreams, work hard, and watch what happens. Good bye boxing.

Boxing is not for killing.

I'm not the greatest; I'm the double greatest. Not only do I knock 'em out, I pick the round

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