Dick Cavett writes of his friendship (and a sad recent encounter) with Muhammad Ali. I think Mr. Cavett is underestimating the physical skills and punishment involved in even a rigged pro wrestling match but he's right about the effect that Ali has long had on people around him. We had "The Champ" (as we were directed to call him) on a show I worked on and then we took him to a wonderful dinner at Roscoe's House of Chicken and Waffles. I can't imagine ever being in a room with someone whose sheer presence excited so many people.
