A woman walks into a bank in New York City and asks for the loan officer. She says she's going to Europe on business for two weeks and needs to borrow $5,000. The bank officer says the bank will need some kind of security for such a loan, so the woman hands over the keys to a new 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. An employee drives the Rolls Royce into the bank's underground garage and parks it there. Two weeks later, the woman returns, repays the $5,000 and the interest, which comes to $15.41. The loan officer approaches her.

''We are very happy to have had your business, and this transaction has worked out very nicely, but we are a little puzzled. While you were away, we checked you out and found that you were a multimillionaire. What puzzles us is why would you bother to borrow $5,000?''

''Where else in New York can I park my car for two weeks for 15 bucks?''
