The murder of a perfectly good differential (reel-1)
Six-panel comic strip for soldiers in the Joe Dope series, styled as a film reel: a title card, then Joe Dope draining a truck's differential oil, distracted by a woman in a red dress, driving off without refilling it, and a sergeant showing him the wrecked gear. The slogan 'Don't be a dope!' is name-calling aimed at the careless mechanic, softened by humour.
