At a golf course, four men approached the sixteenth tee. The straight fairway ran along a road and bike path fenced off on the left.

The first golfer teed off and hooked the ball in that direction. The ball went over the fence and bounced off the bike path onto the road, where it hit the tire of a moving bus and was knocked back on to the fairway.

As they all stood in amazement, one man asked him, "How on earth did you do that?"

He shrugged his shoulders and said, "You have to know the bus schedule."
