Previously:
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!"
Now,
The same truck driver is rolling down the highway a few days later and yet another sports car, this time a red Porshe 911 Turbo, tailgates him in a road with double lines. The driver, another blond, is impatient as usual and generally annoys the truck driver.
Like before, he gestures to the blond to pull over. They both do so, and clamber out of their cars.
He stares at the blond for a short while and pulls out his piece of chalk; he starts to draw a circle in the ground.
However, the blond, wise to his ways, replies, "WAIT just a minute! Don't you try to fool me, I know exactly what you're going to do! My friend told me about you!"
The trucker pauses for a second, then erases the unfinished circle. He then begins to draw again; This time, however, he draws a square.
"Alright," he growls, "now I want you to step into the circle and stare out into the desert. You are not allowed to leave the square. You got that?" "Fine!" says the blond and steps into the square...
