Popeye and Olive are watching through a sporting goods store window. Inside, the athletic saleswoman (a Mae West caricature) is throwing punches at a speedbag, displaying her muscular shape. Popeye insists Olive should learn the art of self defense, and they go in. Popeye demonstrates some boxing moves and, while Olive trains, the blonde sporting-goods lady begins to flirt with the Sailorman. Ms. Oyl notices this and a catfight ensues, with Olive soon beaten to the ground by the athletic woman. Yet she manages to crawl near Popeye's spinach can and, upon gulping down the greens, launches into a rematch with her adversary, who is soon trounced. Popeye then receives his own dose of punches, until Olive calms down.
