There was a young fellow who was quite inventive and was always trying out new things. One day he thought he'd see just how fast a bicycle could go before it became uncontrollable. He asked his friend, who owned an old Mustang, if he could tie his bike to the bumper of his car to test his theory. His friend said "Sure".
