A nice looking blonde was driving and got caught in a really bad
hailstorm. Her cars was covered with dents, so the next day she took it to a
repair
shop. The shop owner, seing she was a blonde, decided he would have a
little fun. He told her just to go home and blow into the tailpipe really
hard, and all the dents would pop out. So the blonde goes home, gets down
on her hands and knees and starts blowing into the tailpipe of her car.
Nothing happend. She blows a little harder and still nothing happens.

Just then, her roommate, another blonde, arrives home and sees what she is
doing. “What are you doing?” she asks. The first blonde tells her how the
repairman had instructed her to blow into the tailpipe in order to get all
the dents to pop out. Her roommate, rolling her eyes, looks at her and
says,……..“HELLO….you need to roll up the windows first!”
