"I say, old chap, this game is getting on, isn't it? We'll miss the scones if this continues much longer. How about we place a little wager to get this over and done with right now?"
"Sounds fine by me, my good man. What do you propose?", replied the Earl of Worchestershire.
"I'll tell you what," retorted Pency, "I'll lay down my bat right now, if you can throw a ping-pong ball so that it will go a short distance, come to a complete stop, and then reverse itself, right back into your hand. But you can't bounce the ball off any object, or tie anything to it. Yes?"
"By jove," chortled the Earl, "That's impossible! If you can do that, I'll happily let you have this game and I'll even make you a nice, hot cup of tea!"
"Well," smiled Pencey, "Here we go..."
How did Lord Pencey manage to show up the Earl of Worchestershire, take the game and enjoy his cuppa?
