In the USA airing, a trailer for the film Poseidon aired during the episode's commercial breaks before Homer's story (a remake of the original film The Poseidon Adventure). Curiously, the third story is a parody of this film.
After only six weeks, this is another episode in the seventeenth season to be a multi-story episode, or to be split into three sections. This is like the "Treehouse of Horror" series or other similar three-part episodes like "Trilogy of Error", from season 12.
The fourth wall is broken when Moe tells the audience that Old Englishmen spoke with "th" at the end of sentences, along with the inclusion of thee, ye and thou. Moe has similarly addressed the audience in one of flashback scenes in, "The Way We Weren't".
Homer and Moe's aggressive competition over Marge's love (as shown in Lisa's story) has been an ongoing gag in the show that especially references to season 16 ("Mommie Beerest").
Bart appears twice in "The Neptune Adventure"; as himself throughout the story, and as Bart Christian/"Capt. Bart-bossa" at the end. The name Bart-bossa appears to be another reference to Pirates of the Caribbean.
This episode also references Samuel Taylor Coleridge's "The Rime of the Ancient Mariner". In the first story, after the storm breaks off, Homer notices an albatross which he eats. Unlike the poem, this action does not lead to unfortunate incidents. The final act with the appearance of the Bounty could possibly be a reference to the appearance of the ghost ship.
Homer's story is a parody of The Poseidon Adventure, an action film. There are several similarities between Homer's story and The Poseidon Adventure. Several characters die in ways similar to the movie: Lenny falls off a ladder into surging water and Comic Book Guy dies while trying to tie a rope underwater, both quite similar to the deaths of major characters in the movie. This episode also aired just weeks before the remake of the movie, titled Poseidon, premiered.
The song played at the beginning of Homer's story is "Rock The Boat" by the Hues Corporation.
Marge is seen at The Frying Dutchman, despite that "New Kid on the Block" revealed that she has a seafood allergy (one that can most likely kill her, due to her line about her throat closing up and her going into convulsions).
In the 2nd story, the maritime flag of Great Britain is shown incorrectly. The correct flag in 1789 would have a blue background, red cross in the centre, and white crosses running diagonally, (as shown in the picture).
