An amateur golfer was talking to his golf pro.
“How do you get so much backspin on your golf ball? Can you teach me how to do that?” he asked.
The golf pro says, “Before I answer that question, let me ask you one first. How far do you hit your seven iron?”
“About 130 yards, I guess”, replies the amateur.
Pro: “Then why on earth would you ever want your golf ball to spin back?”
