Dented Jokes

A blonde was driving home one night and got caught in the middle of a real bad hail storm. With hailstones as big as golf balls, her car got dented up pretty badly.
The next day, she took it to a body shop. The owner, noticing that she was blonde, decided to have some fun and told her she could save some money if, when she got home she would blow real hard in the tailpipe, and the dents would pop out.
When she got home, she started blowing into the tailpipe and her blonde girlfriend saw her. Her friend was startled and asked, “What are you doing? ” So the first girl told her friend what the body shop guy had told her to do.
Her girlfriend says, “You dumb blonde! You need to roll up the windows first. ”
