The Last Blonde Joke

I had heard this one long ago and just recently remembered it again. It's a great joke because (A) it puts other blonde jokes on their ear and (B) actually sounds like a practical piece of advice:

A blonde 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 the loan, so the blonde hands over the keys to a new Rolls Royce.

The car is parked on the street in front of the bank, she has the title and everything checks out. The bank agrees to accept the car as collateral for the loan.

The bank's president and its officers all enjoy a good laugh at the blonde for using a $250,000 Rolls as collateral against a $5,000 loan. An employee of the bank then proceeds to drive the Rolls into the bank's underground garage and parks it there.

Two weeks later, the blonde returns, repays the $5,000 and the interest, which comes to $25.41. The loan officer says, "Miss, we are very happy to have had your business, and this transaction has worked out very nicely, but we are a little puzzled. What puzzles us is, why would you bother to borrow $5,000 on a $250,000 car?"

The blond looks at him coolly and replies "Where else in New York City can I park my car in a guarded lot for two weeks for only $25.41?"
