An unfortunate blonde left her car out in a nasty hail storm one afternoon. When the storm was over, she checked the car and found out that it was covered with small dents.

She went to the local garage and inquired about how to fix the problem. The mechanic jokingly told her to blow on the tailpipe and the dents would be removed. So, she took the car home parked it and proceeded to blow on the pipe.

Another blonde came by and inquired about what she was doing. The first blonde said that she was blowing on the tailpipe to remove the dents.

The other blonde responded, "That's not going to work unless you roll up the windows!"
