Fore!

The 16th tee featured a fairway that ran along a road. The first golfer in a foursome teed off and hooked the ball. It soared over the fence and bounced onto the street, where it hit the tire of a moving bus and ricocheted back onto the fairway.
As they all stood in amazement, one of the golfer's friends asked, "How did you do that?"
The golfer shrugged. "You have to know the bus schedule."
