When the ship is being pulled under, Hermes gets into the ship and closes the door, yet when it is completely submerged, his speedo floats to the top of the water.
Zoidberg claimed he was going to die with his friends when the ship was being pulled under, yet he is a sea creature so he could survive under the water as witnessed when Leela caught him with her fishing line when he was under the water eating a boot.
When Bender says everyone put in five bucks, Fry doesn't give him anything and Zoidberg searches himself and cannot find anything.
When Farnsworth accidentally sprays himself with the fish spray, 8 fish attach to him but you only hear 7 splats.
Among the fish seen are Giant Squid, Sperm Whale, Colossal Mouth Bass, Colecanth, Eletric Eel, Seahorse, and an Angler.
Zoidberg, Bender, and Fry leave the sunken Planet Express ship to search for food. In a subsequent scene, inside the ship, Bender is shown wearing a cook's outfit, along with presumably cooked and eaten food, and, apparently, nobody complaining about it.
Yet, in other Futurama episodes, most notably 30% Iron Chef, we are told that he can't cook!
While trapped on the Planet Express ship at the bottom of the Atlantic Ocean, Bender is shown reading the "Atlantic Monthly", an actual magazine.
In the flashback of Atlanta's sinking, a sign reads, "SeaNN", a parody of the Cable News Network, "CNN".
When Fry tells Bender about Umbriel while he is sleeping, Bender turns a knob labeled "volume". However, in the very next scene, the knob is gone!
This is the second episode in which Bender is seen "jacking on". The first time was in the episode "Hell is other robots".
Opening theme promotion: A STERN WARNING OF THINGS TO COME
Hermes' "Code of Conduct for Cannibalism" rulebook has a decorative bone-patterned border on the cover.
The song being played as Fry and Umbriel are getting to know each other is "Atlantis" by Donovan.
One of the types of bait that Hermes is using, and Zoidberg "samples", is anchovies. But in a previous episode, "A Fishful Of Dollars", we learn that anchovies have been extinct since the 2200's, devoured by Zoidberg's species.
RESPONSE: First, both Hermes and Zoidberg referred to the bait fish as "sardines". Second, though many people consider anchovies and sardines to be the same, they are different species. Refer to the following "Wikipedia" links for further details: Sardines and Anchovies.
How did the ship sink if it is filled with air? And if it did, wouldn't they need some kind of a ballast tank to have it rise to the surface. The fishtail engine wouldn't be enough.
While space is a near vacuum, a space ship would still have to handle high pressure upon re-entry. So it should be able to handle going underwater.
While Amy is sleeping under the parasol, Bender grabs it and bends it into a hook to try to catch a big fish, leaving Amy, wearing a bikini, exposed to the sun. Amy awakens some time later, horrified to discover that she is completely sunburnt. Bender tells her that he put sunblock on her, but it was only on her back. When Amy turns to look at her back, she finds that he used the sunblock to write, "Honk If Bender Is Great", which is clearly visible against her reddened skin. However, later in that scene, when Amy's back is to the viewer, the writing is nowhere to be seen.
Fry: She had a tube top, and a BEAUTIFUL scaly tail, and I think she had hair extensions
Fry: These last twenty-four hours have been the happiest days of my life
Bender: In the event of an emergency my ass can be used as a flotation device.
Umbriel: What the hell is that?
Fry: Yeah I'm a little confused too. How do I... y'know... with the tail and all?
Umbriel: I'm not your first am I? I mean, I-I lay my eggs and leave and you release your fertiliser.
Umbriel: Oh, Fry! I want you to make a mer-woman outta mer-me.
Zoidberg: Well, I guess this is goodbye for me as well.
Zoidberg: You know, Fry, I've got a little place just outside town. You could come visit, maybe?
Fry: Sorry, Zoidberg. I'm trying to join the country club.
Farnsworth: Fry, you half-mad, half-insane maniac, be reasonable. Don't you realise that if you stay at this depth your body will permanently adapt to the pressure?
Fry: Realise it? I don't even understand it!
Leela: But, Fry, what about us? What about your life on the surface? You don't belong down here.
Zoidberg: She's right, I mean, sure, they got the Braves but it's a third-rate symphony.
Bender: Whoa, whoa, whoa. Wouldn't it take millions of years to evolve into mermaids?
Umbriel: Normally, yes, but the caffeine really sped things up. That stuff's wonderful.
Donovan: Atlanta was a city, landlocked, hundreds of miles from the area we now call the Atlantic Ocean, yet so desperate the city's desire for tourism, that they moved offshore, becoming an island, and an even bigger Delta hub, until the city over-developed and it started to sink, knowing their fate, the quality people ran away, Ted Turner, Hank Aaron, Jeff Foxworthy, the guy who invented Coca-Cola, the magician and the other so-called Gods of our legends, though Gods they were, and also Jane Fonda was there. The others chose to remain behind, on their porches with their rifles, and one day evolve into mermaids, and sing and dance and ring in the new.
Mermaids: Hail Atlanta!
Leela: The magician?
Amy: So, Fry, Atlanta was an American city in your time?
Fry: I think it was just an airport. They had a place where you could buy nuts.
Umbriel: No! Ancient Atlanta was more than just a Delta hub. It was a vibrant metropolis, the equal of Paris or New York.
Fry: That's right, honey! Whatever you say.
Umbriel: Look at these fabulous ruins. Turner Field, the Coca-Cola bottling plant, the, uh, the airport.
Fry: Hey, you guys, the most amazing thing happened. It's two-for-one Tuesday at Krispy Kreme! Plus there's mermaids.
Bender: Fry! Oh, I just knew you were still alive!... I owe you 10 bucks, Hermes!
Colonel: Y'all enjoy your stay! Tourism's our main source of income round here so see the sights, spend some money. Please don't leave!
Colonel: Welcome to Atlanta. Folks round these parts call me the Colonel. Here, have some breathers, courtesy of our Chamber of Commerce.
(He hands them breathing gear)
Farnsworth: This is uncomfortable and humiliating. Now, if they could put it in the form of a suppository...
Amy: Dude! An ancient sunken city!
Farnsworth: Could it possibly be? Are the old legends true?... It is! It's the fabled lost city of Atlanta!
Merman: Howdy, y'all!
Zoidberg: I've got his scent! Over here where the water gets warmer.
Farnsworth: Ooh, that reminds me: You've all taken your pressure pills, right?
Amy: Yes! Stop asking!
Umbriel: Tell me more about that bizarre land-y world you come from. Is there water there too?
Fry: Sure. Sometimes it falls from the sky.
Fry: And sometimes it doesn't.
Fry: So, uh, am I gonna drown?
Umbriel: Course not. Just stay calm and let the currents relax your every muscle.
Fry: Aw, yeah!
Umbriel: Did it just get warmer?
Hermes: He must've gone out looking for that mermaid. The poor, demented honky.
Leela: It's ocean madness alright. Sailors call it aqua dementia, the deep-down crazies, the wet willies, the screaming moist!
Leela: Where's Fry?
Bender: I didn't kill him. Professor?
Farnsworth: No, I've been busy.
Farnsworth: I'm almost finish reconfiguring the ships propulsion system. We can leave as soon as the paper-mâché is dry.
Fry: You know what I like best about you, Umbriel? You find me fascinating even when I'm not claiming to be a jewel thief or a lion tamer.
Umbriel: Lions? There are sealions on the land?
Fry: Yup. We call them land-sealions... I tame them!
Fry: I can't believe you're really real. I like your tail.
Umbriel: Oh, you're sweet. I like those wiggly doo-dads comin' outta your hips.
Fry: Oh, thanks. They're called pants.
Fry: Hey! I can breath and talk, just like a fish!
Mermaid: Oh, you speak fish?
Fry: Well I saw a real mermaid and I wish for once my friends would have decency and kindness to believe me.
Leela: Ocean madness.
(Fry storms out)
Farnsworth: He may have ocean madness but that's no excuse for ocean rudeness.
Amy: You think you saw a mermaid?
Fry: No, I did see a mermaid! She was wearing a tube top and she had a beautiful scaly tail. And I think she had hair extensions.
Bender: Yeah, right!
Leela: Sure she did.
Hermes: OK, Fry!
Farnsworth: You're simply hallucinating, you... moron.
Zoidberg: What is it, Fry?
Fry: (blubbering) Mermaid.
Bender: You want some lemonade? You saw a big parade?
Zoidberg: Your student loans have been repaid? Then how 'bout lending your old pal Zoidberg a few bucks, Mr. Millionaire!
Leela: OK, everyone, calm down. The Professor and I will get to work on the ship. Bender, Zoidberg, since you can survive underwater, you'll go out and look for food.
Fry: I'd better go too. They don't know what I like.
Hermes: Fry, no! The pressure will crush you like a green snake under a sugar cane truck.
Hermes: The important thing is that we don't panic. There are rules for situations like this. Now, the first order of business is lunch. I suggest a nice lobster Zoidberg - I mean lobster Newburg - I mean Doctor Zoidberg.
Bender: Tempers are wearing thin. Let's just hope some robot doesn't kill everybody.
Leela: There. Good as new! Except we're three miles below the surface, we don't have any food and the ship won't work underwater.
Bender: People, it's far, far worse than we thought... my fish got away.
Leela: Depth at 45 hundred feet, 48 hundred, 50 hundred! 5000 feet!
Farnsworth: Dear Lord, that's over 150 atmospheres of pressure.
Fry: How many atmospheres can this ship withstand?
Farnsworth: Well it's a spaceship, so I'd say anywhere between zero and one.
Zoidberg: Wait! I'll save us! By cutting the unbreakable diamond filament!
Bender: Hey, I'm snagged.
Farnsworth: It's not snagged, the mechano man has caught something!
Amy: Sunburn! My fabulous body! It's ruined! What happened to my parasol?
Bender: I don't know. It wasn't here when I took your umbrella.
Leela: Wake up, everyone! I've got something. And this time it's alive! (She pulls out another boot with Zoidberg on the end of it and groans.) Dr. Zoidberg, since when do you even wear boots?
Zoidberg: I wasn't wearing it. I was eating it.
Farnsworth: Bender, be careful. That's the ships diamond filament tether. It's unbreakable.
Bender: Then why do I have to be careful?
Farnsworth: It belonged to my grandmother.
(Fry reels in his line, a big fish attached to it)
Fry: Hey, Bender, I just caught a fish this big!
Bender: Quit exaggerating, Fry.
Leela: Bingo! Whatever it is, it's 20 times heavier than a boot.
(She pulls out a crate marked "Boots 10 Pair")
Bender: Couple more of those and you'll have yourself a fish stick!
Fry: Hey, a fish this fine belongs in a fish nugget-style chunklet.
Leela: Aha! Gather round, chumps! I got the winner!
(An old boot comes out of the water on the end of the harpoon)
Amy: Oh, so this is where you shop for your boots?
Fry: I can hit a fish between the eyes from 20 yards!
Bender: Oh, yeah? I can hit a shrimp!
Leela: I'm afraid you're both out of your league, boys, 'cause you're looking at a woman who owns her own harpoon.
Bender: Harpoon, my ass!
(Leela hurls her harpoon into Bender's ass)
Leela: The sun, the sea air, good friends.
Bender: Leela's right, fishing blows. Whattya say we make it interesting?
Hermes: Why not?
Farnsworth: Yeah, cool.
Bender: Everybody kick in five bucks. (Everyone hands him $5) There, wasn't that interesting?
Farnsworth: Ah! The exact centre of the Atlantic Ocean. This seems the logical place for fish to congregate.
(Fry is by a sunken pirate ship with a skull and crossbones on a flag)
Zoidberg: Be careful Fry, that flag is poisonous.
Leela: I'm afraid Fry's suffering from 'ocean madness'.
Fry: Everytime something good happens to me you say it's some kind of madness...or I'm drunk...or I ate too much candy...
Leela: Fry are you alright?
Amy: What about Umbriel?
Fry: Well, it turns out I loved her, but I wasn't IN love with her.
Amy: (whispers) Trouble in bed.
Hermes: Exciting news, people. The pet licence I requisitioned for Nibbler has arrived!
Leela: Hermes, that's sweet. I didn't know you cared about Nibbler.
Hermes: Dream on, woman! I'd like to put the little basta'd in a sack and toss the sack in a rivah and hurl the rivah into space! But I DO like fillin' out requisitions, and these were some doozies!
(tears open envelope)
Hermes: Great Ja's Dreadlocks! There's been a mix-up! This isn't a pet license, it's a fishing license... and its mandatory!
Bender: So, we're in international waters?
Farnsworth: Indeed so.
Bender: (reports on the radio) 'Falcon', this is 'Blue Raven'. 'The Goose' has nested, I repeat 'The Goose' has nested.
(Boat drives up, exchanges packages with Bender, and drives away)
Bender: Hey, guess what you're accessories to?
Farnsworth: Sweet Zombie Jesus! Its huge!
Fry: Oh, why couldn't she be the other kind of mermaid, with the fish part on the top and the lady part on the bottom?
Fry: I can't swallow that...
Farnsworth: Good news!! It's a suppository.
Hermes: I miss my wife and me oxygen.
Farnsworth: Yes, we all miss our loved ones and gasses.
Zoidberg: (while underwater) My house, it burned down! How could this have happened?!
Hermes: That's a very good question.
Bender: So there's where I left my cigar.
Hermes: That just raises further questions!
When played on TBS, instead of the word "Jesus" being blanked out, the entire "Sweet Zombie Jesus!" line was cut from the episode.
In Adult Swim's showing of this episode, Farnsworth's line "Sweet Zombie Jesus" was edited out so Jesus was muted out of the phrase. As a result, he says "Sweet Zombie [Blank]". Adult Swim had a similar editing problem with the Special Rejected, which may never air because of this phrase. However, the full phrase was restored when it aired on Comedy Central.
The noise that is heard when "The Colonel" switches the tourist information screen on is one of the many sound effects used in Star Trek: The Original Series (1966).
Bender: In the event of an emergency, my ass can be used as a flotation device.
In the ninth Star Trek film, Star Trek: Insurrection (1998), Lieutenant Commander Data says "In the event of a water landing, I have been designed to serve as a flotation device" after he, Captain Picard and Anij jump into the river after discovering the holo-ship.
Title: "The Deep South" referred to the states of the most southern part of the eastern side of America (Florida, Georgia, Mississippi,etc.) In the show it is referred as being south of the U.S. and deep underwater.
The water pipes breaking, the glass shattering, the creaking of the ship and Leela counting off the depths are all a parody of the movie Das Boot.
"Atlantis" by Donovan:
The original song, "Atlantis", refers to the people who left the fabled city as, "The Poet, The Physician, The Farmer, The Scientist, The Magician, and the other so-called gods of our legends. Though gods they were."
The Futurama, "Atlanta", version refers to (and shows onscreen) those who left the sinking city of Atlanta, Georgia, as follows: "Ted Turner, Hank Aaron, Jeff Foxworthy, The guy who invented Coca-Cola, The Magician and the other so-called gods of our legends. Though gods they were."
Throughout the show, Hermes exclaims, "My Manwich!", which is a reference to the Hunt's product of ground beef and tomato sauce, typically put on a hamburger bun.
Fry: Oh, why couldn't she be the other kind of mermaid, with the fish part on the top and the lady part on the bottom?
This a reference to an episode of Night Gallery called Lindemann's Catch, about a fisherman who catches a mermaid and falls in love with her. The problem is that she can't breath on the surface and is dying and he wishes for her to lose her tail and gain legs, thus being able to breath. But his wish backfires because her lower half becomes her human half and her human half becomes the fish half.
One of the few references to the book in the series. When the golden statue of Ted Turner is placed on the island of Atlanta, it starts to sink, which is a parody of the biblical story of the Golden Calf. Also, Fry being swallowed by the monstrous bass is a parody of the biblical story of Jonah and the whale.
The Beverly Hillbillies
The line "Y'all come back now, you hear?" is a quick and cheap reference to the classic television show The Beverly Hillbillies.
Atlantis: by Donovan
The description of the fate of Atlanta is like the song's intro. A parody of his own work.
Bender humming the Dueling Banjos tune is a quick and cheap reference to the movie Deliverance.
Umbriel looks a lot like Darryl Hannah, and also speaks in a high-pitched fish language like the film Splash.
The Little Mermaid
Aside from meeting a mermaid the name Umbriel, like Ariel, is the name of a moon of Uranus. Disney named the mermaid Ariel, it wasn't in the original story.
Both the ship being dragged to bottom of the sea by a cable and the use of new technology to breathe underwater are both taken from the movie The Abyss.
20,000 Leagues Under the Sea: by Jules Verne
There are several references and parodies of both the book and the movie version of 20,000 Leagues Under the Sea.
Bender: So there's where I left my cigar.
The way Zoidberg's house is burned down is just like Kramer's cigar burning down the cabin owned by Susan's (Geroge's wife) father in The Bubble Boy on Seinfeld.
