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

If I said I would knock out Sonny Liston in 1 minute and 49 seconds of the first round, that would hurt the gate.

America is the greatest country in the world.

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

I'm the greatest thing that ever lived! I'm the king of the world! I'm a bad man. I'm the prettiest thing that ever lived.

The only thing that matters is submitting to the will of God.
