Fritz, a slow-witted, clumsy, German boy, works as clerk in a grocery store. He is in love with pretty Mamie, who, however, prefers the attentions of Patsey, the champion wrestler and all-around athlete. Patsey chases Fritz away from courting Mamie, which causes Fritz to plot revenge. Fritz eats some limburger cheese and discovers the terrible blows he can inflict as a result. He plots to defeat Patsey, the champion wrestler, and issues a challenge. Fritz then proceeds to train for the match by eating enormous gobs of limburger, punctuated with strings of garlic, while he takes a daily bath in noisome and pungent chemicals. Fritz wins the contest almost without a struggle, but his sweetheart proves false, and he escapes from vengeance of the community with difficulty.
