Betty Ann, a blonde, was driving home one night when she suddenly found herself in the middle of a really bad hail storm.

The hail stones were as big as golf balls and her car was dented up really bad. The next day she took it in to a repair shop to have the dents looked at.

The repair guy, noticing that she was blonde, decided to have some fun and told her to blow into the tail pipe of the car really hard when she got home, and that doing this would cause all of the dents to pop out.

When she got home she started blowing into the tail pipe as hard as she could, over and over.

Just then, her best friend Lisa (who also happened to be blonde) shows up, sees her blowing into the tail pipe and is quite puzzled by the action.

"What are you doing, Betty Ann?" she blurted out.

Betty Ann replied, "Well the repair guy told me to blow into the tail pipe real hard and all the dents will pop out."

Lisa responded, "Duh! You need to roll up the windows first!"
