Putting advice

A young man, his father and his grandfather were about to tee off to start their round when an incredibly good-looking woman walked up to the tee box.
"Would you like to join us and make a foursome?" asked the grandfather.
"I would, but on one condition," replied the lovely young woman. "I prefer to select my own clubs and make my own putts without advice from men. Every other time I've golfed with men, they try to give me advice. Will you agree not to give me advice?"
The men all consented in unison, none of them being particularly good players.
As they soon realized, this young woman was a fabulous golfer. She was getting par on every hole. The men were wondering who would have the nerve to give her advice!
On the eighteenth hole, the woman found herself facing a 35-foot putt, with a severe undulation on the green.

She studied it, and studied it, and studied it. Finally, she said, "Gentlemen, I'm very happy that none of you tried to give me advice before this. I've never played a round with men when at least one of them didn't try to give me some advice. Right now, if I make this putt, I'll have par for the course, and I'm asking for your advice. If you help me and I make this shot, I'll sleep with each one of you!"

The young man rushed over, studied the putt, and said, "You have to aim for that small bush to the left of the hole, that should be the right break!"
The father ran over and studied the putt, then said, "No, I think you should aim at the knot on the log to the left of the hole, and that will be the right break!"
The grandfather walked up to the ball. "Heck," he said, calmly picking up the ball, "that's a gimme."
