Wisdom is knowing when you can't be wise.

How many push ups do you do? I don't know. I only starts counting when it starts hurting

The sweetness of life lies in dispensing with formalities.

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

I'm The Greatest, but only in relation to fighting.

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

Don't ever squeeze a fighter's hand, man. You're doing good just to lay your eyes on me
