A Jack Russell terrier? My god. He'll burn you up. They never stop. A German shepherd, you can only go so many miles.

When I was a boxer, I wanted to be champion of the world, not the richest man in the world.

Today the biggest decisions I make aren't related to the heavyweight title. They are whether I visit McDonalds, Burger King, Wendy's, or Jack-in-the-Box.

I don't even think about a retirement program because I'm working for the Lord, for the Almighty. And even thought the Lord's pay isn't very high, his retirement program is, you might say, out of this world.

Anybody going into boxing already has brain damage.

All I've ever tried to tell anyone is that I'm not a black man or a white man or anything else. All I've ever been was an American.

Sonny Liston stood up to me and actually made me give ground. No one has ever done that to me before or since.
