Kurt and Patrick were heading out to play a round of golf one day when Patrick showed up without any balls in his bag.

"no problem," he said to Kurt, "I'll just use an imaginary ball."

At the eighteenth hole Patrick was in the lead by a stroke.

Kurt was fed up with competing with Patrick and his imaginary ball.

"I'm going to use an imaginary ball this time too," said Kurt.

He steps up and swings his club and says "there, 280 yards straight down the middle."

Patrick steps up and swings, "all right, 275 yards straight up the gut."

Off they go, when they reached their shots, Patrick seeing he had 150 yards to go took out his 7 iron and hit his shot. "Hey, look at this, it's going straight at the flag, it rolling right at it, it's in the hole, I win."

"Not so fast," said Kurt, "you've just disqualified yourself."

"What are you talking about," said Patrick.

"You hit my ball."
