How on Earth did you do that?

A foursome approached the sixteenth tee. The straight fairway ran along a road and bike path fenced off on the left. The first golfer teed of and hooked the ball into that direction. But 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 silent amazement, one man finally asked him, “How on earth did you do that?” He shrugged his shoulders and said, “You have to know the bus schedule.”
