Horseplay that causes accidents is sabotage!
Navy Department safety poster: a caricature drawing of a horse-headed man with a wide toothy grin and tears of laughter, under the lettering 'HORSEPLAY'. The caption labels such play 'sabotage', applying a wartime term for deliberate enemy damage to workplace accidents, a name-calling label meant to make careless fooling feel like an act against the war effort.
