Marge babysits for Rod and Todd that goes against Ned's strict parenting, while Bart gets kidnapped by a chimp who turns out to be Mr. Teeny's mom.

!!!Tropes:
* ImStandingRightHere: While consoling Homer over losing the rubber duck race, Marge admits that Bart's performance at a soccer game was terrible, unaware that [[RightBehindMe he was right behind her]].
* ShoutOut: The windmill that Homer and his rubber duck go through has similarities to the titular building from ''Disney/TheOldMill''.
* {{Spoonerism}}: While going through the mill, Homer keeps saying to himself "Protect the duck!". After getting bonked on the head enough, he mumbles "Produck the tect".
