One time, this blonde was driving down the road, and rear-ended a trucker.
They both pulled over, and got out.
The trucker takes a piece of chalk, and draws a circle on the road, and tells the blonde, "Do not step out of that circle or else!"
The trucker then turns away from the blonde, and slits her tires.
He looks back at the blonde who is giggling, so he bashes in her windshield.
This time the blonde is laughing, so he keys her car, outraged the trucker turns to the blonde beacause she is busting out laughing and says, "What's your problem?!"
The blonde says, "When you weren't looking, I stepped out of the circle three times."
