A group of four guys got together regularly to play golf, but one day, one them was sick, so a new member named George filled in. He played well and was pleasant, so they asked him to join them again the following Sunday, at 9:30am.

George said, "Fine, but I may be about ten minutes late. Wait for me."

The following Sunday, George showed up right on time. Not only that, but he played left-handed and beat them.

They agreed to meet the following Sunday at 9:30am. George again said, "Okay, but I may be about ten minutes late. Wait for me."

The next Sunday, there was George, at 9:30 on the dot. This time he played right-handed, and beat them again. "Okay, 9:30 next Sunday?" one of the foursome asked.

George said, "Sure, if I can be ten minutes late."

Another golfer jumped in, "Wait a minute. You always say you may be ten minutes late. But you're always right on time and you beat us whether you play right or left-handed."

George said, "That's true -- I'm superstitious. If I wake up and my wife is sleeping on her right side, I play right-handed. If shes sleeping on her left side, I play left-handed."

"And what if shes lying on her back?"

George said, "Thats when I'm ten minutes late!"
