Of all the improbable outcomes to a motorcycle wreck. After two racers crash, their motorcycles hook horns in such a fashion that the wheels are still moving so they just spin in a circle and further destroy themselves. It's like killing a spider but then the thing's legs refuse to die. Well, the bikes didn't stop and half of the fun was watching their frustrated owners throw fits trying to catch them. I haven't seen anyone try so hard and fail at catching something since this.
