Hail Storm

A blonde was driving back from the mall when there was a terrible hailstorm. Huge hailstones the size of golf balls pelted her car leaving it full of dents. She drove to the body shop and asked what she should do.
The body man explained what needed to be done and that it would cost at least $4000 to repair. She said that was too much and wasn’t there some other way to fix it. The body man decided to have a little fun and said, “Well you could blow into the tailpipe real hard and they might pop back out.”
She decided to give it a try before spending that much money.
She drove home and was in the garage with her lips wrapped around the exhaust pipe when her blonde neighbour came over to visit. “What are you doing?” she shrieked, thinking the worst and thankful that she may have just prevented her friend from committing suicide.
“I’m blowing into the tailpipe real hard to pop all these dents out of my car,” explained the first blonde.
“Well silly, it’s not going to work,” replied her neighbour.
“Why not,” she asked?
“Because you’ve got to roll up the windows first!”
