A golfer, playing a couple rounds by himself, is about to tee the ball off, and a sheisty salesman runs up to him, and yells, "Wait! Before you tee off, I have something really amazing to show you!"The golfer, annoyed, says, "What is it?" "It's a super special golf ball," says the sheisty salesman. "You can never lose it!" "Whattaya mean," scoffs the unbelieving golfer, "you can never lose it? What if you hit it into the water?" "No problem," says the sheisty salesman. "It floats, and it detects where the shore is, and spins towards it." "Well, what if you hit it into the woods?" "Easy," says the sheisty salesman. "It emits a beeping sound, and you can find it with your eyes closed." "Okay," says the golfer, impressed. "But what if your round goes late and it gets dark?" "No problem, sir, this golf ball glows in the dark! I'm telling you, you can never lose this golf ball!" The golfer buys it at once. "Just one question," he says to the salesman. "Where did you get it?" "I found it."
