The loan

Before going to Europe on business, a man drove his Rolls-Royce to a downtown New York City bank and went in to ask for an immediate loan of $5,000.

The bank officer says the bank will need some kind of security for such a loan. So the businessman 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. An employee drives the Rolls into the bank's underground garage and parks it there.

Two weeks later, the businessman returns, repays the $5,000 and the interest, which comes to $15.40. The loan officer says, "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 are a multimillionaire. What puzzles us is: why would you bother to borrow $5,000?"

The man smiled. "Where else could I park my Rolls-Royce in Manhattan for two weeks and pay only $15.40?"

Peter C. Doherty

Born 15 Oct 1940.Australian immunologist and pathologist who, with Swiss-born Rolf Zinkernagel, shared the Nobel Prize for Physiology or Medicine in 1996 for their project at the John Curtin School of Medical Research in Canberra, Australia (1973-5). Using mice, they studied how the immune system's T-lymphocytes, recognize virus-infected cells from healthy cells. The "killer T-cells," in a test tube killed cells infected by a virus, and worked only against a specific virus in a specific mouse and could not be transferred to a different animal. Such discoveries have a wide impact on the study of diseases such as rheumatic conditions, multiple sclerosis and diabetes. He was the seventh Australian Nobelist, and the first who was a veterinarian.
