 The story that Billy Crystal (qv) tells about his "best day" of  going to a Yankee game with his father is a true story from his  childhood. He notes at one point that, "I still have the program."  Not only does he really still have it, but he got Mickey Mantle to  autograph it twice: once at the game that day and once again some 20  years later on a talk show they were both guests on.
