Joke: The $5,000 loan A shrewd physician walks into a bank in Boston and asks for the loan officer. He says that he's going to Europe on business for two weeks and needs to borrow $5,000. The bank officer says that the bank will need some kind of security for such a loan; so the doctor hands over the keys to a Rolls Royce parked on the street in front of the bank. Everything checks out, and the bank agrees to accept the car as collateral for the loan. A bank employee takes the keys and drives the Rolls into the bank's underground parking lot. Two weeks later, the doctor returns from his trip, repays the $5,000 loan as well as the $15.41 of interest that had accrued. The loan officer, with a puzzled look on his face, says to the doctor, "We are very happy to have had your business, and this transaction worked out very nicely. However, while you were away, we checked out your finances and discovered that you are a multi-millionaire. If this is true, why would you bother to borrow $5,000?" "Where else would I be able to park my Rolls Royce for two weeks for only 15 bucks?!?", replied the doctor.
