I got one for you that is slightly related, lets see if I remember it.
This guy is driving down the road in a nice sports car, when off to the side of the reaod he sees a kid sitting on a bike. He pulls over and finds out the kids chain fell off his bike. The guy offers to tow the boy down to a gas station where he can fix the bike. The kid is reluctant at first, but the man says he will go slow and if the kid wants to stop just to ring the bell on his bike. The kid finally agrees and the guys ties a rope to his car and hands one end to the boy. They start off slowly down the road.
They pull up to a red light and stop, then in the lane beside thme come another man in another sports car. He revs his engine, and in turn so does the man helping the boy. The light turns green and both drivers slam on the gas. They are quickly going 90mph when they pass the gas station. A cop happens to be at the gas station sitting in his car when he hears and then sees the cars racing down the road followed closely by the kid on his bike ringing the bell. He radios into his boss and says "Sarge you'll never believe what i just saw." The sarge says what, and the cop says "two sports cars racing down the road." The sarge says, so what that happens all the time. And the cop says yeah, but what amazed me is the little boy on his bike trying to pass them.
