Two Blonds

Two blonds decided to go shopping. A few hours later they come out and the first blond realizes that she has locked her keys in the car, so they spent a few hours pacing around the car trying to figure out what to do. Finally, the first blond looks off into the distance and sees storm clouds. She turns to her friend and says, “Quick, think of something because a storm is coming and I left the convertible top open!”
