Popeye and Olive Oyl watch a woman doing some good boxing. They are both impressed. Popeye tries to teach Olive self-defense. It does not go well. The lady boxer is quite a sexy gal which has a terrific effect on Popeye. Olive notices and she hates it. Eventually, it turns into a real cat fight. Literally.
Obviously, we all know who is eating the spinach in this one. I do have an issue with Popeye. This story would still work even without him going gaga over the sexy boxer. It is the same issue with Olive's lust for Bluto. It never makes these characters look good. That's why this romance is not one of the greats.
