One fine day, Jim and Bill are out golfing. Jim slices his ball deep into a wooded ravine. He grabs his 7-iron and proceeds down the embankment into the ravine in search of his ball. The brush is quite thick, but Jim searches diligently and suddenly he spots something shiny. As he gets closer, he realizes that the shiny object is in fact a 7-iron in the hands of a skeleton lying near an old golf ball.
Jim excitedly calls out to his golfing partner: "Hey Bill, come here; I’ve got some trouble down here."
Bill comes running over to the edge of the ravine and calls out: "What’s the matter Jim? Everything OK?"
Jim shouts back in a nervous voice: "Throw me my 8-iron! Apparently, you can’t get out of here with a 7."
