Wait isn't it a dis-service to nominate all these nice people for Battys>? Batteries hurt!
I modify my second of [165]'s nomination to include a rider stipulating only watch batteries may be flung in his general direction, that safety goggles be provided & all battery chuckers must be high. Or, barring those terms a full suit of downhill armour painted florescent pink & yellow can be worn if only D cells are available.
