I'm the best. I just haven't played yet.

I hated every minute of training, but I said, ''Don't quit. Suffer now and live the rest of your life as a champion.''

Expect the best, Prepare for the worst.

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.

Sonny Liston is nothing. The man can't talk. The man can't fight. The man needs talking lessons. The man needs boxing lessons. And since he's gonna fight me, he needs falling lessons.

I've seen George Foreman shadow boxing, and the shadow won.
