There was this guy at the golf course that was always cheating. He never played a straight game of golf. Always improving his lie, taking mulligans, etc. It got so bad that no one ever wanted to play a round with him.

One day the golf pro walked up to him and said, "We're going to go out and play a round and I'm going to show you how you’re supposed to play this game. There will be absolutely no cheating. It'll be an honest game of golf."
The man looked sort of disappointed but replied, "Well, alright."

On the first tee, the pro decided to let the man go first so that he could keep an eye on him.
After setting up his shot, the man finally tees off and really slices the ball. It passes through a couple of trees, bounces twice, rolls and then comes to a stop on the cart path.

Then the pro tees of and hits a really straight ball right down the middle of the fairway.
They put their clubs away and proceed down the fairway to hit their second shot.

Upon arriving to his ball, the man reaches down to pick it up and move it off the path. The pro sees this and says, "Hey, wait a minute. You've got to play that ball where it stopped. Haven't you ever heard the phrase 'play it where it lays'?”

The man replies, "Well yeah, but I can't hit the ball when it's on the cart path."
"Well you have too", the pro says. "It's in the rule book."

The man frowns and seems to ponder the issue for a moment. "Well, alright." He replies. He walks over, grabs a club, and addresses his ball. He starts his back swing and then proceeds to scrape the club head across the pavement, sparks flying everywhere, and hit a beautiful shot that lands on the green and stops two feet from the hole.

The pro in wonderment says, "Wow! That was a beautiful shot. What did you use on that?"

The man looks at him and replies, "Your four iron."
