In reading a biography of Joe Namath, I found a little tidbit about Ernest Hemingway. Apparently Hemingway was often on the lookout for sparring partners and, according to a fellow who was one such partner, the candidates were told not to throw any "rights" at Papa, and to also watch their testicles in a clinch because he often would hit below the belt then. I know Hemingway did a fair amount of boxing, but if this story is true then it doesn't show Papa in the best light.
Another tidbit that I discovered in the Namath book is that Namath was the star of a motorcycle movie back in the 70s called C. C. & Company. I actually remember this movie with some fondness but had completely forgotten that Namath was in it. Broadway Joe was also in a spaghetti western, which must have been pretty bad because I had never heard of it before.
