A blonde was having a lot of problems selling her old car, because the
car had 250,000 miles on it. One day, she told her problem to a
brunette she worked with at a salon. The brunette told her, "There is
a possibility to make the car easier to sell, but it's not legal."
"That doesn't matter," replied the blonde, "if I only can sell the
car." 
"Okay," said the brunette. "Here is the address of a friend of mine.
He owns a car repair shop. Tell him I sent you and he will turn the
counter in your car back to 50,000 miles. Then it should not be a
problem to sell your car anymore." The following weekend, the blonde
made the trip to the mechanic. About a month after that, the brunette
asked the blonde, "Did you sell your car?" "No," replied the blonde,
"why should I? It only has 50,000 miles on it."
