Jack Dempsey

When I was a young fellow I was knocked down plenty. I wanted to stay down, but I couldn't. I had to collect the two dollars for winning or go hungry. I had to get up. I was one of those hungry fighters. You could have hit me on the chin with a sledgehammer for five dollars. When you haven't eaten for two days you'll understand.

All the time he's boxing, he's thinking. All the time he was thinking, I was hitting him.
