Kids will play Kid games. One of mine was to 'bloody' a white T-shirt with ketchup and wait till right after dark. I'd hide in the huge bushes beside our house and watch for cars coming down the street. I should mention, I also had a round wooden stake about 2 feet long covered in blood (ketchup) for a prop. When the car got close to my place, I would stagger out onto the front lawn and collapse near the curb. Great bit of theater.
My plan was, if anybody stopped (to help ?), I was going to jump up and run away laughing.
Well, no one ever stopped.....Except a Cop Car one time. I told them I was conducting a 'Scientific Experiment'.
