A musical moment in the home is spoiled by LeRoy’s attempt at singing. Gildersleeves puts him to doing his homework. When Throckmorton decides to give the kids a lesson in money, and earning a living. He takes them to the City Hall to see where he works, and what he does. Suddenly an emergency pops up, low water pressure. Gildy takes the kids to talk to Charlie, out at the Ressevoir. It looks like a bad snifter valve. Darn those pesky snifter valves, always breaking, and always out of stock. Especially with the wartime shortages.
Gildy pushes the issue, and the water pump breaks. Poor old Charlie gets blamed. When Gildersleeves is called into the Mayors carpet to take the blame, he has to apologize to Charlie, the engineer, and try to get him back on the job. He also has to go on the radio to explain the situation. Gildy does what he can to help Charlie, and so does LeRoy as he is still working on a school report about Gildersleeve’s job.
In the end, all is well, and LeRoy even gets a good grade on his report, which he reads aloud. A fairly true and accurate report of his uncle’s vocation. Maybe a little too true and accurate for Gildersleeve’s taste.
In epilog: A final note to encourage gathering waste paper to help the war effort.
