Four guys who worked together always golfed as a group at 7:00 a.m. on Sunday. Unfortunately, one of them got transferred out of town and they were talking about trying to fill out the foursome. A woman expressed some interest in joining them. They were hesitant, but said she would come once to try it, and they would see what they thought. They allagreed and she said, "Good, I'll be there at 6:30 or 6:45." She showed up right at 6:30, and wound up setting a course record with a 7-under par round. The guys went nuts and everyone in the clubhouse congratulated her. Meanwhile, she was fun and pleasant the entire round. The guys happily invited her back the next week and she said, "Sure, I'll be here at 6:30 or 6:45." Again, she showed up at 6:30 Sunday morning. Only this time, she played left-handed, and matched her 7-under par score of the previous week. By now the guys were totally amazed, and they asked her to join the group for keeps. They had a beer after their round, and one of the guys asked her, "How do you decide if you're going to golf right-handed or left-handed?" She said, "That's easy. Before I leave for the golf course, I pull the covers off my husband, who sleeps in the nude. If his "you-know-what" is pointing to the right, I golf right-handed; if it's pointed to the left, I golf left-handed. One of the guys asked, "What if it's pointed straight up?" She said, "Then I'll be here at 6:45."
