God gave me Parkinson's syndrome to show me I'm not 'The Greatest' - he is.

If the boxers are a little more colorful, talk a little like I did and just do half as much as I did for boxing, it will be all right.

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

I figured that if I said it enough, I would convince the world that I really was the greatest.

Shut up, I know what I'm doing!

Whatever the challenge was, however unattainable the goal may have seemed, I never let anyone talk me out of believing in myself.

If you want to be equal with me, you can get your own Rolls-Royce, your own house and your own million dollars.
