The truck's driver made her pull over into a parking lot and get out of the car.
He took a piece of chalk and drew a circle on the pavement. He told her to stand in the middle and not leave the circle.
Furious, he went over to her car and slashed the tires.
The blond started laughing.
This made the man angrier so he smashed her windshield.
This time the blond laughed even harder.
Livid, the man broke all her windows and keyed her car.
The blond is now laughing hysterically, so the truck driver asks her what's so funny.
The blond giggles and replies, "When you weren't looking, I stepped out of the circle three times!"
