A blonde is driving home and she gets caught in a really bad hailstorm. The hail is as big as tennis balls, and she ends up with her car covered with large dents. So the next day she takes her car to the repair shop.

The shop owner, seeing she is blonde, decides to have a little fun. He tells her just to go home and blow into the tail pipe, really hard, and all the dents will just pop out.

The blonde drives home, gets out of the car, gets down on her hands and knees and starts blowing into the tail pipe.

Nothing happened. So she blew a little harder, and still nothing happens.

Meanwhile, her roommate, also a blonde, comes home and asks,"What in the world are you doing?"

The blonde car owner tells her how the repairman had instructed her to blow into the tailpipe in order to get all the hail dents to pop out.

Her blonde roommate rolls her eyes and says, "Hell-OOOO! Don't you think you should roll up the windows first?
