One day, you find yourself walking past a large curtain draped along the side of the street—a curtain like those they use in game shows to hide the grand prize from the audience and contestants.  Suddenly, a salesman jumps out from behind the curtain to inform you that he is about to make you an offer that you cannot possibly refuse.  He tells you that for a mere $100,000, he will sell you the brand new, top-of-the-range Mercedes-Benz luxury sports car (worth a cool half-million dollars) parked on the other side of the curtain.   Your interest is piqued and you tell him to go ahead and show you the car, but the salesman says no, he can’t do that, and that you will just have to take his word for it that the offer is genuine.
