Boxer Kid Dynamite is offering $100 to anyone who can stay in the ring with him for three rounds without going down. Uncle Joe is trying to find a fighter who he can train, while keeping the majority of the prize money as a training fee. He thinks he's found that person in Herman Crawley, the strong as an ox but not too bright plumber Kate hires. Joe sets up a makeshift boxing ring at the hotel to train Herman, which doesn't sit too well with Kate. When Joe meets Kid Dynamite and his brazen manager mother Mrs. Hogan, Joe thinks there's no way Herman can lose. So Joe makes a $500 versus the hotel side wager with Mrs. Hogan on the outcome. What Uncle Joe doesn't realize is that Herman has a particular weakness. Uncle Joe has to protect Herman's weakness and find out and exploit the Kid's weakness. Even though Herman prevails, the fight is not as profitable as it should have been.

Kate hopes to have a convention take place at the hotel. But, they are in competition with the Pixley Hotel, which has more modern conveniences. Kate decides to do a face lift of the hotel's rooms, with Uncle Joe doing most of the work. Meanwhile, Kate gets a letter telling her of a property tax increase of $6. She is relieved but Uncle Joe is livid. Joe sends a scathing letter to J.C. Albright, of the tax review board, demanding the taxes be lowered. Albright decides to go to the Shady Rest to handle the problem personally. Uncle Joe makes the hotel look as shabby and run-down as possible to justify the tax decrease. Mr. Forbes, the convention organizer, arrives and Joe mistakes him for J.C. Albright. Mr. Forbes decides against the Shady Rest for the convention. After fixing the hotel up again, J.C. Albright arrives and Joe thinks he's the convention organizer. Despite losing the convention, they do get a refund on their taxes.
