If you're not familiar with George Plimpton, he was a writer who was famous for trying to participate in pro sports. His accounts of his pathetic attempts to compete are always pretty funny. He's most famous for his book about his pre-season stint with the Detroit Lions ("Paper Lion"), but this book was his first experience as a participant.
He had a deal to pitch to All-Star lineups from each league. The deal was that he would pitch his way through each lineup once, and whichever team had the most total bases against him would win the prize.
His description of the beating he took is hilarious, and so are the notes from a friend he had in the stands. The guy told him that after the P.A. announcer told the crowd that George Plimpton, of Sports Illustrated would be facing the All-Star lineups the fans seemed confused. One kept asking who this "George Prufrock" guy was.
