I saw him on David Letterman many, many years ago. He was funny and self depreciating. But as he talked all I could think about was, “How many times did Ali get hit in the face with that fist?” Jeeze. His fist was the size of my head! He became a heavyweight champion a second time at 46, the oldest ever, then retired at 48. Through a fluke endorsement deal, he became rich and famous again for selling indoor grills. He named all his kids George (for the girls, some female variation). What a life.
