Henry pushed through the multi-armed power blaster, then plowed into the heavy hanging dummy. Laura cringed at the force with which her nephew smacked the thing, which was likely filled with a hundred pounds of sand. Digging his feet into the soft earth, Henry drove the equipment down the rail -- but the hefty dummy didn't stop at the end. It whizzed off its support arm and crashed to the ground, taking Henry with it. Behind Laura, the cheerleaders laughed, along with several of the players. Lura expected her nephew to roll over and leap to his feet, then give her his huge grin and thumbs-up, but he didn't move from where he'd landed. With a growing sense of horror, Laura wondered if the prankster had struck again--this time with truly terrible consequences.
