Sports Illustrated columnist and senior writer Rick Reilly convinced 12 golfers (including such pros and well-known amateurs as Jack Nicklaus, Tommy Aaron and Donald Trump) to let him serve as their caddy; he chronicles his experiences, both humorous and humiliating, in Who's Your Caddy: Looping for the Great, Near Great and Reprobates of Golf. Doubleday's first printing was 100,000; three trips back to press up the number to 123,000. Reilly's eight-city tour finishes on Father's Day weekend at the U.S. Open at Olympia Fields, a Chicago suburb.
