Blonde Repair Job

Blonde Repair Job     A blonde was driving her car home one night when she suddenly found herself in the middle of a dreadful hailstorm.   The hailstones were as big as golf balls and her car got dented up very badly.     The next day, she takes the car to a repair shop to have the dents looked at. The repair guy, noticing that she is blonde and pretty flaky, decides to have some fun and tells her to blow into the tailpipe of the car really hard when she gets home, and that doing so will cause all of the dents to pop out.     When she gets home, she starts blowing into the tailpipe as hard as she can, over and over. Just then, her best friend -- who also is blonde -- shows up.     Her friend sees her blowing into the tailpipe and is quite startled by the action. She blurts out: "What are you doing?"   She tells her the repair guy told her to blow into the tailpipe real hard and the dents would pop out.     Her girlfriend says:   "Duh! You need to roll up the windows first!"
