Blonde Rolls Back The Odometer

A blonde wanted to sell her car, but couldn't find any buyers. She called her friend for advice, and her friend asked her how many miles she had on her car.

"235,000 miles." Her friend told her that was the problem.  But the blonde's friend told her that her brother is a mechanic and could put back the miles to whatever she wanted. So the blonde went to the mechanic and told him to put the miles at 40,000. Two days later the blond's friend asked her if she sold the car since her brother dropped the miles.  The blonde told her, "Why would I sell the car? There are only 40,000 miles on it!"
