The circle!!

[SubmarinerMan]

A blonde has just gotten a new sports car. She cuts out in front of a semi, and almost causes it to drive over a cliff. The driver furiously motions for her to pull over, and she does. The driver gets out and draws a circle and tells her to stand in it. Then he gets out his knife and cuts up her leather seats. He turns around and sees she's smiling. So he goes to his truck, takes out a baseball bat, and starts busting her windows and beating her car. He looks back to see that she's laughing. He's really mad now, so he takes his knife and slices her tires. He turns around and she's laughing so hard, she's about to fall down. He demands, "What's so funny?" She says, "Every time you weren't looking, I stepped out of the circle!"
