Back in 1985, George Plimpton pulled off one of the all-time great April Fool's hoaxes, penning "The Curious Case of Sidd Finch" in the April 1 issue of SI. According to Plimpton, Finch was a mysterious rookie in training with the New York Mets. An eccentric character who only wore one shoe while pitching -- a ratty hiker's boat -- Finch allegedly threw the ball 168 mph. Despite the ridiculousness of the piece, many SI readers actually believed Finch existed. SI finally announced it was a hoax on April 15. Here are the pictures that accompanied the original SI story, as well as some that were never published.
