Bobby Jones was one of the greatest golfers to ever compete, uniquely known for winning the "Grand Slam" of golf winning all four major tournaments in the U.S. and Britain in a single year. In 1925, early in his career, having reached the final playoff in the U.S. Open, at a certain point in the match, Jones was setting up to strike his ball which was in the rough just off the fairway. His iron accidentally touched the ball. He immediately became angry with himself, turned to the marshals, and called a penalty on himself.
