some more blondes

A blonde was driving home after a game and got caught in a really bad
hailstorm. Her car was covered with
dents, so the next day she took it to a repair shop.

The shop owner saw that she was a blonde, so he decided to have some 
fun.
He told her just to go home and
blow into the tail pipe really hard, and all the dents would pop out.

So, the blonde went home, got down on her hands and knees and started
blowing into her tailpipe. Nothing 
happened. So she blew a little harder, and still nothing happened. Her
roommate, another blonde, came home
and said, "What are you doing?"

The first blonde told her how the repairman had instructed her to blow 
into
the tail pipe in order to get all the
dents to pop out. The roommate rolled her eyes and said, "Uh, like
hello!
You need to roll up the windows first."
