A blonde was driving home from the game and got caught in a really bad hailstorm. Her car covered in dents, the next day she took it to a reapir shop. The owner, seeing she was blond, decided to have a bit of fun and told it would be easier, and cheaper, if she blew into the tail pipe. “Blow hard enough and the dents will pop right out.”
So the blonde went home, got onto her knees, and tried it out. Nothing. She blew harder. Still nothing. Even harder. Zip.
Her roommate, another blonde, came out and asked what she was doing. The first blonde explained what the shop owner had told her.
The roommate rolled her eyes and said, “Hello! You’re supposed to roll up the windows first!”
