S18E10 The Wife Aquatic
While watching a home movie, Marge becomes depressed as she is reminded of memorable childhood vacations spent at Barnacle Bay. Hating to see Marge sad, Homer and the kids take her on a surprise trip to the bay, only to discover that it has turned into a rundown mess due to the absence of fish. Homer and the kids lovingly give the boardwalk a whole new makeover for Marge. But when Homer accidentally lights the renovated carousal on fire, stirring up an angry mob of townspeople, more than just waves come crashing down.
