A golfer is in a competitive match with a friend, who is ahead by a couple of strokes.

"Boy, I'd give anything to sink this putt,"  the golfer mumbles to himself.

Just then, a stranger walks up beside  him and whispers, "Would you be willing to give up one-fourth of your sex life?"

Thinking the man is crazy and his answer  will be meaningless, the golfer also feels that maybe this is a good omen, so he says, "Sure," 
and sinks the putt.

Two holes later, he mumbles to himself again, "Gee, I sure would like to get an eagle on this one."

The same stranger is at his side again and whispers, "Would it be worth giving up another fourth of your sex life?"

Shrugging, the golfer replies, "Okay." And he makes an eagle.

On the final hole, the golfer needs another eagle to win.

Without waiting for him to say anything, the stranger quickly moves to his side and says, "Would winning this match be worth giving up the rest of your sex life?"

"Definitely," the golfer replies, and he makes the eagle.

As the golfer is walking to the club house, the stranger walks alongside him and says, "I haven't really been fair with you because you don't know who I am. I'm Satan, and from this day forward you will have no sex life."

"Nice to meet you," the golfer replies, "I'm Father O'Malley."

That's a goodie.
