A dumb blonde is driving down the freeway in her brand new cherry-red Lamborghini with not another car in sight when she comes across a big truck. This truck is going a tad too slow for her liking, and being in a no-passing zone, she vents her frustration by repeatedly blaring the horn at him.
This really gets on the truck driver's nerves, and he motions for her to pull over. They both pull onto the shoulder and get out of their vehicles.
After briefly gazing at the blonde, and at the surrounding desert, the truck driver walks up to her and pulls out a piece of chalk. He uses the chalk to draw a circle on the pavement and then returns his gaze to the blonde.
"Okay," he says in a gruff, threatening voice, "now I want you to step into the circle and stare out into the desert. You are not allowed to leave the circle. You got that?" "Sure," replies the blonde casually, and she steps into the circle. The truck driver then goes to his truck and gets out a sledgehammer.
With a mighty grunt of exertion, he begins to beat the living crap out of the blonde's car. By the time he's done, her car is nothing more than a crumpled up piece of scrap. Satisfied with his handiwork, he turns to face the blonde.
But, much to his surprise, she starts laughing uncontrollably. "What the hell are you laughing about?" the truck driver demands, "I just completely totalled your car!" The blonde is now rolling on the ground laughing, and in between giggles she says: "When you weren't looking, I stepped out of the circle!"
