Marge revisits her summer vacation spot from childhood only to learn that it's gone to pot from overfishing.

!! Tropes:
* AdviceBackfire: At the end of he episode, Lisa tells the people of Barnacle Bay to stop overfishing. They agree...and decide to go into logging. Lisa considers this even worse.
* BittersweetEnding: The fish are now under conservation, and Barnacle Bay is in business again. But all the trees are cut down to be used for pornography. Lisa considers this a DownerEnding, however.
* ContinuityNod:
** To the trip to [[Recap/TheSimpsonsS13E15BlameItOnLisa Brazil]].
** Even Barnacle Bay is aware of Milhouse's crush on Lisa [[Recap/TheSimpsonsS15E22FraudcastNews because of Mr. Burns]].
* {{Foreshadowing}}: One of the scenes in Marge's home movies was of her watching a net full of Yum-Yum Fish get loaded onto the dock.
* TakeThat: Lisa and Bart consider Brazil the worst place they've ever been to next to Barnacle Bay.
** {{Bowdlerization}}: In the Brazilian dub, the disparaging reference to Brazil was re-edited to make it seem like Bart and Lisa were wholeheartedly agreeing that Barnacle Bay was the worst place they've ever been.
* TreesIntoToothpicks: The episode ends with Barnacle Bay going into the logging business, with the logs being used for porno magazines. Lisa is horrified.
