A blonde was driving home & got caught in a 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 fun with her... He told her to go home and blow into the tail pipe really hard, & all the dents would pop out.
So, the blonde went home, got down on her hands & knees & started blowing into her tailpipe.. Nothing happened.. So she blew a little harder, & still nothing happened.
Her blonde roommate saw her & asked, '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 & said, 'Uh, like hello! You need to roll up the windows first.'
