Entering a car showroom, a man is grabbed by a salesman and guided round the latest, gleaming convertible sports car. The prospective customer announces that he is interested in purchasing the vehicle and enquires about the price. The salesman types some figures into his computer and says, "That particular model will cost you two pink fluffy notes with rhinos on and seven yellow clown coins, Sir" " I'm not paying that" protests the customer, " That's silly money."
