Three friends who had a regular 8:00 am golf game were standing on the first tee waiting to begin. They noticed a stranger who was standing on the putting green, by himself. They asked him if he would like to play along. He agreed, and the match began. The three of them agreed that the stranger, a right-handed player, had a great swing. Sure enough, he made 18 straight pars. Enthusiastic about the great player they had met, they asked him if he would like to play the next day. “Sure, and I won’t be more than two minutes late.”
The next morning the stranger was there, right on time. To their amazement, however, he took out a set of left-handed golf clubs. Using a perfect left-handed swing, he again made 18 straight pars. The group was overwhelmed. The invitation was again extended for the next morning. “I’d love to play. I won’t be more than two minutes late.”
The next morning, the stranger arrived…as he warned, two minutes late.
The group could no longer hold their curiosity. One of the said, “Hey, buddy, you’re the greatest golfer we’ve ever played with. You made 18 pars in a row the first day right-handed and 18 pars in a row the second day left-handed. How do you possibly decide from which side you will play?”
“Oh, that’s easy”, the stranger answered. “I use my wife as a guide. If she wakes up on her right side, I play right-handed. If she wakes up on her left side, I play left-handed.”
“What if she wakes up on her back?”, one of the three asked.
“That’s when I’m two minutes late.”
