Homer gets into trouble over his football gambling debts and allows the Springfield Mafia to shoot a porno film in the house; Marge leaves for the beach—and encounters a marine biologist named Caleb (voiced by Alec Baldwin) who has dedicated his life to saving manatees.

!! Tropes:

* GenreSavvy: When Marge phones home and Homer tries to apologize, she figures out he'll be waiting for her with a box of half-eaten bonbons. Homer is indeed eating some of them at this moment.
* {{Irony}}: The Santa village where Homer sends his family to so they won't know he's allowing the local mafia to make a porn movie at their home doesn't open during Christmas.
* TooDumbToLive: After Homer convinces some bullies on jet skis to leave the manatees alone, Homer insults them.
