Bob is waiting to tee off for the start of his round when he sees Joe just finishing his round. Bob notices that Joe is wet all over the front of his trousers. Curiosity gets the best of him, so Bob asks Joe how he got so wet. Joe tells the following story: That day, Joe had played golf for the first time with bi-focals. All day long, he could see two sizes for everything. There was a big club and a little club; a big ball and a little ball; etc. So, Joe said that he hit the little ball with the big club and it went straight and long all day long. On the green, he putted the little ball into the big cup. He said that he played the best golf of his life. Bob said, "I understand that, but how did you get all wet?" "Well," said Joe, "when I got to the 16th, I had to urinate awfully bad. I went into the woods and unzipped my fly. When I looked down, there were two of them also; a big one and a little one. Well, I knew the big one was'nt mine, so I put it back."
