Accidental Dance Craze: Patrick starts one by being mistaken for the only competitor in a dance competition to not use a partner.
Accidental Marriage: In 'Truth or Square' Sandy and SpongeBob act out a marriage, without telling the very real priest it was just a play.
In 'Mermaid Man and Barnacle Boy', a delusional, senile Mermaid Man, a confused SpongeBob and the warden of Shady Shoals take part in this hilarious exchange.
Mermaid Man: Listen up you villains, I wanna eat my meat loaf! Now if you don't get out of here, then with the power invested in me, I now pronounce you man and wife! Warden: WHAT IS GOING ON IN HERE?! Mermaid Man: (Talking to the warden, pointing at SpongeBob) You may kiss the bride! Patrick: (SpongeBob is thrown out of Shady Shoals and rolls home, where Patrick is waiting for him) Did you reunite our heroes? SpongeBob: No. But I'm married.
Acting Unnatural: "Life of Crime". SpongeBob and Patrick are panicking because (they think) they stole a balloon. SpongeBob advises, "Just act natural," and, whether out of nerves or sheer stupidity, both of them start gibbering and acting crazy. They are immediately surrounded by a crowd who mistake them for street performers.
In the episode "Boating School", when SpongeBob is asked to act natural, he gets on all fours and starts grazing like a cow.
Inverted in the episode "The Bully", once SpongeBob believes Flats will come searching for him in the bathroom, he says he must "act natural". Cue him floating around in the toilet looking like a real kitchen sponge.
Also an actual case with Adam West and Burt Ward playing the younger versions of Mermaid Man and Barnacle Boy who are usually played by Ernest Borgnine and Tim Conway respectively, in an obvious homage to The 1960's Batman.
Pun-happy film critic Gene Shalit appearing as pun-happy food critic "Gene Scallop" in The Krusty Sponge. In the Spongebob universe Gene is a harsh critic whose review can make or break a restaurant.
Afraid of Doctors: In the episode "Suds", Patrick tells SpongeBob that the doctor's is a horrible place to go. Of course, while SpongeBob believed him, he asked if Patrick could be his doctor, but that didn't help cure the suds. As Sandy took SpongeBob to the real doctor for the sponge treatment, he realizes that it isn't such a bad place after all and was given a lollipop. Proven wrong by this, Patrick asks for the sponge treatment, but he was proven right as the treatment didn't turned out to be so well.
Ageless Birthday Episode: In the episode "SpongeBob Meets the Strangler", SpongeBob celebrates his birthday among several other parties he planned on the same day. Even though he has a revealed birthday, his age isn't revealed.
Another episode when Spongebob was invited to his grandmother's birthday. All was said about her age was "turning...even older".
AI Is A Crap Shoot: Plankton's computer wife, Karen, plays and subverts this to an extent, she is seemingly more competent and intelligent than Plankton but was created with the sentience of a nagging housewife (and an Obnoxious In-Laws program as back-up software) and thus is more preoccupied in pointing out Plankton's stupidity or whining for affection from her husband than doing much constructive.
In addition, nearly anything technological that SpongeBob or Squidward buy is bound to work wrong in some manner, like Le Spatula or Squidward's house security system.
All Just a Dream: The episodes "Procrastination" and "Doing Time." It is taken to the extreme in the latter.
All There in the Manual: Do you want to know what anti-sea-rhinoceros undergarments look like? Just play the game based on "The Camping Episode".
Bikini bottom is actually the bottom of the ocean near Bikini Atoll, where the United states conducted several nuclear tests in the forties and fifties. If you watch the show carefully you can actually find several references to these nuclear tests, for example large explosions will be real video of the Able nuclear test.
In "Bubble Buddy", SpongeBob enthusiastically celebrates "Leif Erikson Day" ("hinga-dinga-dürgen!"), since, for him, every day must be a holiday. Presumably the writers were not aware, since the whole joke is that he had to make the holiday up, but Leif Erikson Day is in fact a real holiday. It's October 9.
This is possibly lampshaded in one episode, where SpongeBob, who has been running from a bully that wants to beat him up, is finally cornered. The bully then punches him, and SpongeBob actually realizes that it doesn't hurt since he's a sponge and absorbs the blows. He then goes through the rest of his day, all night, and through part of the next day with the bully punching him non-stop, the only response being a loud squeaking noise.
SpongeBob hurts himself to amuse children for Mr.Krabs.
Or the episode where SpongeBob offering to "Lend a hand". Cue him pulling off one arm with the other, only have have another pop out instantly until the ground is covered with yellow arms.
The same thing happens when Squidward is telling SpongeBob a scary story about a man who chopped his hand off with a knife, and SpongeBob doesn't understand that fish's arms don't grow back like his (even Squidward is shocked it doesn't hurt SpongeBob at all).
Angrish: "Ah regga fregga smelinolin Mr. Krabs! Yugga hugga hollin wallet! Zibby mibby spibb! Yolla holla MR. KRABS WALLET!!!"
"I had no idea SpongeBob had such a colorful vocabulary..."
Anti-Advice: In "Pizza Delivery," when SpongeBob and Squidward get lost together, SpongeBob predicts which way to go using his pioneering skills. Squidward goes the opposite way. The camera then pans over to show that their houses are just over a ridge in the direction SpongeBob wanted to go.
Anything But That!: When Squidward finds out about SpongeBob's splinter and threatens to tell Mr. Krabs about it so he'll have to leave work early in "The Splinter"
When SpongeBob thought (incorrectly) that Sandy had tried to get the jump on him at work, as part of their friendly karate (or "ka-rah-tay" as some call it) sparring:
SpongeBob: Thought you could sneak up on me at work, did ya? Well, ya can't! 'Cause I'm fast, I'm mean, and I can do THIS! [clasps hands together and wiggles arms]
Squidward tempting fate during the episode "Pizza Delivery," after he implored SpongeBob to back up the boatmobile, despite the latter's protests that he's still in boating school. Of course, it goes hilariously wrong:
SpongeBob: Backing up! Backing up! [backs up... for miles, until the car dies] ... backing up.
Squidward: Well... ya backed up. And you know what?! I think we're out of gas! And you know what else?! We're in the middle of nowhere!
1. I want to be treated like a superhero not a sidekick. 2. I want to be called "Barnacle Man". 3. I want an adult sized Krabby Patty.
When Mrs. Puff is stealing SpongeBob's new boat, he's not letting go for giant clams, cheese graters, and... EDUCATIONAL TELEVISION!? OH NO! AAAAAAAAAAAAAAAAAAAAAAA
From "Life of Crime": "We're not talking about some dumb mail fraud scheme or hijacking here...WE STOLE A BALLOON! And they're gonna lock us up forever!"
In "Graveyard Shift";
Squidward: He cut off own hand by mistake! [...] He replaced his hand, with a rusty spatula...And then! He got hit by a bus! And then! At his funeral...they fired him!
Art Attacker: In one episode, an artist's pencil which can bring to life a disgruntled duplicate of SpongeBob falls into Bikini Bottom. The pencil and eraser are both used to attack and defend.
Fun Trivia Point: the artist himself, briefly seen in live-action at the start and close of this episode ("Frankendoodle") is played by Mr. Lawrence, an artist, voice actor (most notably Plankton) and ocassional writer for the show.
Art Evolution: Season one looks very different. It was the only season to use hand-painted traditional animation cels, and some character designs are slightly different. With season two, the series abandoned cels in favour of the newer digital ink-and-paint process. The series evolved slightly more after The Movie, in which the animation is more fluid and a little closer to that of the movie.
The Artifact: Recent seasons just barely acknowledge the fact that Bikini Bottom takes place underwater. Some episodes contain underwater thunderstorms, for example.
Awesome, but Impractical: Mermaid Man and Barnacle Boy have an invisible boatmobile... that they struggle to find more than once, since it's invisble. Barnacle Boy has also accidentally, and painfully, sat on the gear lever ("I told you we should have got the automatic"), and has been burned by the tailpipe while unknowingly standing behind it.
Ax-Crazy: Mr. Krabs is often a step away from this because of his extreme obsession with the money. Watch the episode "Clams".
Balloon-Bursting Bird: In the Valentine's Day episode, SpongeBob's gift for Patrick is a hot air balloon made of chocolate. Sandy is to fly it to the carnival but is delayed when scallops (which act as birds on the show's setting) try to eat the balloon.
Based on a Great Big Lie: This is actually parodied in the episode "Arrgh!". SpongeBob and Patrick quickly come to believe their pirate quest is a scam (and that Mr. Krabs has gone Cloudcuckoolander) finding out the treasure map is just a game board they used earlier in the episode. Chance kicks in as they do find the treasure according to the map (the game board) with the remarks of SpongeBob saying "It really IS based on a true treasure map!" The Flying Dutchman comes in to take his treasure back, willing to share with SpongeBob and Patrick. But much to the dismay of Mr. Krabs, he only gains a piece from the game board, and gets replied "But it's based on a REAL treasure chest!"
It's notable that this is rather Karmic, as it was a fight over the treasure (Patrick and SpongeBob wanted their shares, Krabs wanted it all) that woke up TFD in the first place.
Beach Bury: SpongeBob buries a beach goer, Scooter, and then asks Bubble Buddy, his inanimate friend, to unbury him before the tide raises. We later see him as an angel.
Harsher in Hindsight: When you realize Bubble Buddy was alive (not inanimate) the whole time and just let Scooter die.
In the episode "Ripped Pants", a whale is buried in the sand.
Befriending The Enemy: In the episode F.U.N. Spongebob tries to befriend Plankton and ask him to play with him after seeing how Bikini Bottom treats him badly and calls him “a loser”. Plankton decides to go along with it, and use it as an opportunity to steal the Krabby Patty formula. After sharing a Friendship Song together Plankton does become his friend for a time, but ultimately choses to betray Spongebob and steal a Krabby Patty at the end of the episode because “evil is just too fun”. This kind of scenario has been recycled several times in the show usually with Plankton trying to exploit Spongebob in a new scheme.
SpongeBob: Oh, Squidward! It's terrible! Mr. Krabs! Talking to radio! Beeping sounds! Strange dancing! ... robot!
Being Watched: "It feels like someone... wants to sell me something!" (Salesman behind a rock, to fellow salesman) "I told you he was onto us!"
Berserk Button: Whatever you do, NEVER call Patrick "tubby". Or eat his chocolate bars and lollipops...you flatfoots !
Up to Eleven in the the video game version of Truth or Square, where when SpongeBob called Patrick tubby, Patrick turns into a huge one-eyed robot intent on crushing SpongeBob with a mace. Though the battle apparently only happened in SpongeBob's head as SpongeBob was in Plankton's machine the ENTIRE time.
In Sandy's case, don't talk smack about Texas, or you will die.
Or rip all of her fur off (she will make you into bikinis), or even kick her in the butt, Patrick does this (responding to SpongeBob's previous comment about kicking), and she ends up clobbering him with a trombone.
The time SpongeBob called Gary a lady to humiliate and demean him. Sandy happened to be nearby, Overhearing this, she kicked SpongeBob's butt the very next day.
When you live in SpongeBob's house after losing your job, don't make SpongeBob work and slave with the cooking, feeding and the nursing while you lie in bed every day and stay in his house for over six months, or else he'll go ballistic. Squidward had to learn this the hard way.
For crying out, if you're supposed to train to scare people, don't party in SpongeBob's house or he will say "GET! OUT!" in an outraged manner!
"FREEEEE FOOOOOD?!" "...Day...OFF?!?!?!?!?!"
And don't ever tamper with the Krabby Patty formula in front of Mr. Krabs, for that matter. Unless he finds out that it's a way to make more money.
Free refills?! Automated cash registers?! Really, the list goes on....
FOR YOUR LIFE, DO NOT POGO DANCE WITH PATRICK WITH SPONGEBOB IN PLAIN SIGHT!
Don't use the word "overtime" around Mr. Krabs.
Or refer to his hands as Big Meaty Claws!
Apparently, you should never use Krabby Patty meat as any footwear around SpongeBob, or he will hurt you. (Episode: Battle of Bikini Bottom).
Stanley: Wow! A TV! Uncle Sherm never let me watch TV back at home. SpongeBob: Why not? *The TV explodes* Stanley: That's why. *runs off* What's that? SpongeBob: Oh, it's okay. There's nothing good on television anyway.*turns to camera* Nothing.
"The Krusty Sponge" may be this, regarding the series' wild success and Nickelodeon's subsequent milking.
"Keep Bikini Bottom Beautiful". Squidward manages to one-up Squilliam, but get a littering ticket for the umpteenth time.
Bizarchitecture: "Who lives in a pineapple under the sea?" Answer: SpongeBob SquarePants
The other giant objects that the characters live in. Although they're only giant in comparison with the characters, according to the movie.
Well, most of the important buildings follow a sort of a theme, in that they're the sort of things that might appear as decor in fishtanks. Moai, rocks, treasure chests, etc.
Black Comedy: This show, especially in its earlier seasons, contains a surprising amount of dark humor. For example, the entire comedy of "Nasty Patty" comes from SpongeBob and Krabs believing that they've killed the health inspector (he was just unconscious).
Then in "No Free Rides," Mrs. Puff imagines Spongebob running over a family, complete with sound effects, after she graduates him.
Pretty much "Spongebob meets the Strangler", but there's one scene where Spongebob tries to climb on the Strangler's shoulders.... come from nowhere, he appears wearing a pair of shoes with sharp celats, he jumps and his shoes went directly inside the Strangler's eyeholes... "I'm trying, but my cleats are stuck in your corneas!!!" Just auch.
In "The Camping Episode" Squidward gets his poor body beaten several times by the sea bear. If you think that a slapstick routine can't be considered as dark comedy, you wait to see how physically destroyed the sea bear left Squidward's body, only to beat the shit out of him over and over. And that's funny only because his suffering.
The Blind Leading the Blind: "Your Shoe's Untied", where Patrick buys shoes, but doesn't know how to tie them. SpongeBob tries to teach him how, but realizes he's never learned himself.
Patrick often gives SpongeBob this kind of misguided advice. For example, one episode has Patrick teaching Spongebob how to be mature, with tips such as growing sideburns, puffing out his chest, and developing an appreciation for freestyle jazz. Hilarity Ensues.
Since they're both mentally six, they're occasionally known to do this to themselves-devoid of anyone to provide them with questionable advice, they'll attempt to deduce the proper course themselves and arrive at exactly the wrong answer through some of the unsoundest logic it's possible to come across.
In the 'pilot' episode where Spongebob meets Sandy for the first time, Spongebob goes to Patrick for advice about the mysterious concept of 'air'. Patrick claims she means 'putting on airs', or fancy talk. His advice is to go to Sandy's and 'When In Doubt, Pinky Out'. This causes Spongebob, an aquatic animal, to slowly dry out in Sandy's 'treedome'. Patrick enters at one point, and the duo end up completely drying out, but Sandy saves them with water-filled helmets (which become standard attire when visiting her). So, not only is Patrick's advice misguided, it's even dangerous.
Blowing a Raspberry: One episode, SpongeBob goes to Rock Bottom, where everyone speaks in raspberries. When he asks for directions, a Rock Bottomite can't understand his "accent" until SpongeBob starts adding raspberries between words.
SpongeBob also does this to Mr Krabs in The Movie, angry about not getting the job of Krusty Krab 2 manager:
Boot Camp Episode: When SpongeBob gets Mrs. Puff fired after failing the boating exam once again, her replacement is a drill instructor named Sarge. A drill instructor who just so happens to be Zaeed Massani
Boredom Montage: "Squidville": Squidward moves into a new neighborhood where everyone has the same interests and hobbies as he does, and gradually gets sick of it, as the Boredom Montage gradually shows him getting less and less interested by the second. And then he loses it BIG TIME. He attacks people with a reef blower, sings songs, and acts just like Spongebob used to. At the end of the episode, Squidward uses the reef blower as a jetpack while laughing madly (underwater, no less). It then shows Spongebob and Patrick, who were searching for Squidward, unable to find him because everyone looks the same. They then hear Squidward laughing, look up, and say "Well at least we know one thing; it SURE isn't that guy!" Episode ends.
Bottle Episode: "Gary Takes a Bath." It's shorter than the typical 11 minutes, features only one voice actor, features two main characters other than a brief Mr. Krabs cameo and most of it takes place inside Spongebob's pineapple.
Box-and-Stick Trap: One Nickelodeon Magazine comic had SpongeBob and Patrick try this as one of their attempts at catching the Sea Leprechaun, with a Bland-Name Product version of Lucky Charms as the bait. It fails thrice: first it catches Patrick ("I got hungry."), then Mr. Krabs ("I can't resist a free breakfast"), then Plankton ("If Krabs has it, I want it!"). They then decide they need a new plan.
In "It's a SpongeBob Christmas", Patrick attempts to catch Santa Claus using one. He then forgets about his plan, and goes after the Christmas cookie he planted in it.
SpongeBob:(strangles Mr. Krabs) "Listen, you crustaceous cheapskate!! Squidward has been living in MY HOUSE driving me CRAZY!! AND YOU'RE NOT GONNA HIRE HIM BACK ALL BECAUSE OF A STUPID DIME?!?!"
Break the Haughty: Squidward in "Can You Spare A Dime?". After he quits his job at the Krusty Krab, within two weeks he's lost his house, his belongings, has been forced to live on the streets and beg for change, and had to eat all of the art that he made because no one would buy them. And this is all coming from the most self-centered character on the show that's convinced he's the greatest man under the sea.
Brick Joke: In what is possibly a parody on the Trope Namer, "The Two Faces of Squidward" has a fish gain the ability to fly out of seeing handsome Squidward, and then proceed to lose his untied shoe. Later in the episode, the shoe falls through the roof of the Krusty Krab, causing SpongeBob to push Squidward into a pole to save him from being hit on the head with it.
"The Great Snail Race" has one. SpongeBob, who's training Gary, calls him a lady to "humiliate and demean him". Cut to Sandy, who says "I don't know why, but I think I'll kick SpongeBob's butt tomorrow.". The next day, at the end of the episode, Sandy comes out of nowhere, kicks SpongeBob off screen and yells "That's for yesterday SquarePants!".
In the beginning of The Smoking Peanut, Mr. Krabs is seen abusing the concept of Free Day, taking everything he can. At the end of the episode, it's revealed that the oyster got upset because her pearl was stolen. Guess who stole it?
In the "Nasty Patty" episode: SpongeBob reveals that Mr. Krabs wears hair curlers to bed. Remember what Mr. Krabs "borrowed" from Mrs. Puff in the "Life of Crime" episode? Her hair curlers (although it was a gift, supposedly).
Also, in "Something Smells", Patrick says that he has no sister. Several SEASONS later, "Big Sister Sam" focuses around Patrick meeting up with his long-lost sister.
Broken Smile: Mr. Krabs at the end of "Squid on Strike", when he sees that SpongeBob destroyed the Krusty Krab.
Bug Catching: SpongeBob and Patrick go jellyfishing all the time.
Butt Monkey: Most of the cast have their share of bad luck, but Squidward and Plankton are the most consistent examples. Almost everything is out to get them, and is merciless in execution.
Entire episodes revolve around Squidward trying desperately to get away from SpongeBob and Patrick. He also has had houses land on him, had a shrunk submarine grow back to normal size while inside his body (with SpongeBob and Patrick in it), had a NUCLEAR BOMB thrown directly in his face (which promptly exploded), had his house repeatedly destroyed... well, you get the idea. And these only the instances invoked by people who LIKE him. Outside of that generally a large amount of Bikini Bottom's residents, animals and inanimate objects seem to bear an instant grudge towards Squidward, usually expressing it in somewhat violent or hurtful ways. At least the majority of abuse SpongeBob and Patrick inflict is completely accidental.
There's also the unnamed health inspector from "Nasty Patty".
If there's an episode that primarily focuses on SpongeBob himself, chances are something terrible is going to happen to him.
The Tattletale Strangler deserves special mention.
Butt Sticker: In episode "Kracked Krabs" when SpongeBob gives a quarter with a string to a very large employee, he pulls it back along with employee and he lands on SpongeBob. He then turns around revealing SpongeBob stuck to his backside.
Subverted in Nature Pants. Patrick tearfully tells SpongeBob, "Even Squidward misses you!"; cut to Squidward celebrating the fact that SpongeBob's gone.
Played straight in Squidsville. Squidward is initially delighted to live in a neighborhood where everyone lives and acts like him, but eventually is bored by it and starts playing with a reef blower like SpongeBob.
Can't Take Criticism: In "The Algae's Greener on the Other Side", during his review at work, Spongebob insists on being given some form of critism to improve upon. Eventually, despite being assured he is doing perfectly, his boss relents and suggests to put less sauce in the burgers, leaving Spongebob in a deranged whimpering BSOD.
In one of the live-action sections of "SpongeBob's House Party", Patchy the Pirate introduces us to "Longbeard the Pirate".
And Mr. Krabs' grandfather is a pirate named Redbeard.
Captain Obvious: Every word of dialogue from this incredibly underrated scene from "Wet Painters" where Spongebob and Patrick make their last desperate attempt to get the the paint off of Mr. Krabs's first dollar (after attempting to machine-wash it, sand it, and spray it). Spongebob: (brandishes baseball bat) NOTHING'S WORKING!!! Patrick: Wait, Spongebob! We're NOT CAVE-MEN! WE HAVE TECH-NOLOGY...(smashes computer against desk, as hard as humanly possible, 6 times in a row, to try to get the paint off of the dollar) DERP DERP DERP DERP DERP DERP!!! Spongebob: It didn't work.
Cardboard Box Home: In the episode "Can You Spare A Dime?", a homeless Squidward is living in a cardboard box. That is, until the repo man comes to repossess it.
Carnivore Confusion: Hugely averted. Sharks and killer whales are portrayed as normal people, sea monsters are intellectual giants while fairly harmless creatures such as plankton and flounder are the show's main antagonists.
Cash Lure: In "Frankendoodle," SpongeBob does this to Squidward.
Cerebus Syndrome: Season seven introduced an actual and extremely dark Story Arc with amongst other things, Plankton trying to commit suicide.
Chaos Architecture: Spongebob's pineapple, Squidward's Easter Island home, and Patrick's rock are constantly subject to change depending on the episode. Patrick's rock is justified on account of Patrick making most of the furniture out of sand. The interior of the Krusty Krab is rather consistent, although the location of it is subject to change as well.
Chekhov's Gun: The starfish that was on Mermaid Man's face since his first appearance turns out to be the thing giving him the ability to breathe. Mermaid Man is narrating. Then again, all of the origin stories are wacky and unreliable, so who's to say...
First shown in Season One's "Tea At the Treedome", Spongebob & Patrick's ability to be brought back to life from dehydration comes in handy in The Movie.
In "Sandy, SpongeBob, and The Worm", the paper clip and the piece of string which Sandy uses to lasso a tree and swing up onto the worm when she and SpongeBob are being chased by the worm.
Chirping Crickets: Played with in "Squirrel Jokes": SpongeBob's first joke produces dead silence from the audience, except for a cricket chirping. On his second joke, even the cricket doesn't bother to make noise.
Circle of Standing Stones: In one episode, Spongebob creates a stone statue of himself, complete with holes, to distract the jellyfishes who are attracted to the sound coming from SB's holes when the wind blows through them (it's a very windy day). Turns out that one small statue doesn't work, and then SB creates more, bigger ones and arranges them in a circle. It works very well, with the stones even creating music.
At the end of "Krusty Love", SpongeBob lets out a stream of...gibberish that is obviously intended to be interpreted as cursing.
Mrs. Puff: I had no idea Spongebob had such a colourful vocabulary! Mr. Krabs: ... (Gaping in shocked silence with his jaw on the ground)
Cobweb Of Disuse: In "Pretty Patties", the Krusty Krab is covered in cobwebs when business gets slow. SpongeBob tries to clean one, a spider makes another one. Later, Mr. Krabs himself is seen covered in cobwebs.
Spongebob practices driving while blindfolded. When it comes time for him to take his driving test, he finds he can't drive without the blindfold. Oddly this one provides a justification: when he can see what he's doing, it terrifies him.
"Missin Identity" had him forget where he put his nametag. So he repeats his morning routine ad infinitum, exactly, hoping that this'll help him remembers.
Conjoined Twins: Has happened several times: in the movie, we meet two conjoined twins in a bar. In "SquidBob TentaclePants", SpongeBob and Squidward are conjoined because of one of Sandy's experiments. And then there's this infamous quote:
One particularly egregious example is the episode "Can You Spare a Dime?", where SpongeBob pokes Squidward's animated nose, and the entire rest of his head is a much-darker matte painting (see 9:34-9:40 here).
One of the thugs that wants to enter the Salty Spitoon tells about how he ate a bowl of nails for breakfast. "Without any milk!". In The Movie one of the thugs in the bar is shown eating a bowl of nails. And yes, without milk.
In the April Fools episode, Patrick mistakenly says a depressed SpongeBob was "impressed" by Squidward's prank. In Squidward's Tiki Land, Patrick mentions a time he was feeling "impressed".
The villain, Man Ray, was cryogenically frozen in tartar sauce for a number of years before being unwittingly thawed out by SpongeBob and Patrick, thus he is still in his physical peak. In a much later episode, Manray recognizes an old lady as someone he went to high school with. There was even an episode where SpongeBob and Patrick travel back in time and accidentally stop Man Ray from being frozen originally, thus creating a Bad Future where Man Ray is the ruler. Hilarity Ensues.
The episodes "New Leaf" and "Spy Buddies" featured the robot Krabs suit from an earlier episode "Imitation Krabs".
In "Chum Bucket Supreme", Patrick gives the Chum Bucket a slogan. Said slogan is later seen on a billboard in "SpongeBob's Last Stand".
In "Rock a Bye Bivalve", Patrick is always seen watching a show where someone gets hit in the head with a coconut with music playing. In "The Thing" Patrick and SpongeBob are watching TV and the music for the show plays again, with Patrick saying he thinks he seen this before and this part is real funny.
In "Born Again Krabs", Mr.Krabs is going to be thrown into Davy Jones locker with his gym socks. In Spongebob vs. The big one The Flying Dutchman locks him self in there by accident and the actor Davy Jones throws the socks at him.
In "Spongebob Vs. The Big One", Sandy has a helicopter. That exact helicopter is seen later in "The Krabby Patty That Ate Bikini Bottom" and "Single Cell Anniversary".
In Patrick's dream in "Home Sweet Rubble", Patrick has pictures on the wall that were pictures of him from "Squidward's School for Grown Ups".
In "Spongebob, You're Fired!", we see a Freeze-Frame Bonus of a patty with pickles tucked in, similar to the competition with Neptune in a much earlier episode. Also, the snail food company is mentioned again, by name.
Crack Defeat: In the episode 'The Great Snail Race' had Spongebob, Squidward, and Patrick's pet snails (Gary, Snellie, and Rocky respectively)pitting against each other. Snellie, who is a pure-breed snail, would've won, but she forfeited and comforted an overworked Gary. So the winner? Rocky! It needs to be said that Rocky was an actual rock. How it legitimately got to the finish line was never explained.
Crapsack World: After the movie, Bikini Bottom may qualify. Hence, as shown, is a city full of grumpy people, jerkasses, idiots and tend to be incredibly racist, hating mammalian species (like squirrels) and among them by skin color (see episode "Sun Bleached" ). Is there anything else to add? Most inhabitants have callous and sadistic tendencies, see episodes like "No Hat For Pat" and "Spongicus" where several residents of Bikini Bottom, frankly naturally seem to enjoy the pain of others and killing as entertainment!
Cross-Popping Veins: Squidward does it towards the end of both "Tentacle-Vision" and "Squid's Visit".
Comically Missing the Point: Mrs. Puff in "The Bully", whom doesn't seem to notice Flats' threats of violence against Spongebob. When Spongebob asks Mrs. Puff to settle it, she claims that it's part of Flats's tradition, once again failing to realize Flats's ultimate goal. At the end of it all, the blame all goes to Spongebob.
Spongebob repeats a similar act in "A Pal for Gary".
Cut Lex Luthor a Check: Plankton. He is a scientific genius, capable of creating time machines and the like, (among other things that could be tweaked to benefit all ocean life) and yet he insists on working his way up to the top by running a dingy restaurant whose food is Human Resources. Oh, and trying to steal the Krabby Patty recipe, despite the fact that as long as Krabs is also in business, he'll get all the customers because of the aforementioned dinginess of his restaurant. This was worked around in Plan Z, which would have worked if he had tried this ingenious plan from the beginning, before Krabs hired SpongeBob, instead of using countless plans that were doomed to fail.
