An Iranian man walks into a New York City bank and asks for the loan officer. He says he’s going to Europe on business for two weeks and needs to borrow $5000. The bank officer says the bank will need some kind of security for the loan, so the Iranian hands over the keys to a new Rolls Royce, which costs quarter of a million dollars. …… “The car is parked on the street in front of the bank,” says the Iranian, “and I have all the necessary papers.” … … The bank officer agrees to accept the car as collateral for the loan. After the Iranian leaves, the loan officer, the bank’s president and all their colleagues enjoy a good laugh at the man for using a $250,000 Rolls Royce as collateral against a $5,000 loan. … One of the employees drives the Rolls into the bank’s underground garage and parks it there. Two weeks later, the Iranian man returns, repays the $5000 and the interest, which comes to $15.41. … … The loan officer says, “Sir, I must tell you, we’re all a little puzzled. While you were away, we checked you out and discovered that you’re a multimillionaire. … … Why would you bother to borrow $5,000?” … … The man replies, “Where else in New York City can I park my car for two weeks for only $15.41?”
