The Danza: In "Mermaid Man Begins", the real names of Mermaid Man and Barnacle Boy are revealed to be Ernie and Tim. Mermaid Man and Barnacle Boy are voiced by Ernest Borgnine and Tim Conway, respectively.
Darkest Hour: In "SpongeBob's Last Stand", Plankton has successfully driven the Krusty Krab's customers to the Chum Bucket, and Mr. Krabs has no choice but to give Plankton the Kraby Patty Secret Formula.
Squidward: For the Bikini Bottom Snail Race. Snellie will be winning this Sunday. Patrick: Sunday? SpongeBob: Well, I guess I can't enter Gary in that. Sunday's Laundry day! Squidward: What?! No, SpongeBob. You can't enter Gary because Gary's a mutt! (close-up of Gary looking exactly like a mutt) SpongeBob: Boy, you got that right. Gary's no—HEY!! What makes you think Gary couldn't win that race?
Also in 'Ghost Host', where a customer falls asleep on a mattress being sold to him. The Flying Dutchman comes in and tries to scare the sleeping dude, but no matter how much he tries, he won't wake up. Only when The Flying Dutchman gave up and the salesman has come back already did the customer wake up and scream in terror.
Delicious Fruit Pies: Parodied in "Mermaid Man vs. SpongeBob", with the "Krusty Kids Meal" commercial at the beginning of the episode.
Man Ray: How can I be evil with flavors this good?
Usually the character interpretations fall on who the character in focus is. If the focus is Squidward's life being ruined, then SpongeBob and Patrick will have nothing bad happen to them, while when the focus is instead SpongeBob having a problem, everything bad will instead happen to him, usually caused by Patrick.
Derelict Graveyard: Bikini Bottom itself. The Mall, Thug Tug from The Movie, The Krusty Krab moble, and the Boating Museum and most contents are all shipwrecks.
Destructive Saviour: In "Wormy", Spongebob and Patrick sound the alarm about a monster (actually a butterfly) and send the city in a panic that causes far more destruction than the "monster" would have ever caused.
On the episode "Sandy, Spongebob, and the Worm", Spongebob and Sandy managed to drive a giant worm away as it fell down a large cliff. However, at the same time the citizens of Bikini Bottom were pushing the city somewhere else in an attempt to get away from the previously mentioned worm and the city ended up at the bottom of the cliff that the worm fell in and so the giant worm landed on top of Bikini Bottom, destroying it.
Actually, he also ran past a Don't Walk sign and resisted arrest as well.
In "Demolition Doofus", SpongeBob injured Mrs. Puff and causes her inflation sac to burst. As a result, she enters him in a demolition derby so he would be killed (yes, I said "killed").
In "Little Yellow Book", Squidward gets shamed by the whole town, kicked out of his house, and arrested for reading SpongeBob's diary.
The "Fools in April" episode started with Spongebob playing harmless pranks on people in Bikini Bottom, who all thought they were kind of funny, until Squidward got so irritated by Spongebob's laughing he pulled an elaborate and humiliating prank that ended in Spongebob running off in tears with everyone else shaming Squidward for it. Squidward struggles to apologize until the guilt consumes him and he performs an anguished declaration apologizing to Spongebob. It turned out Spongebob was only pretending to be heartbroken as another prank.
In "Party Pooper Pants," the police arrested SpongeBob for not inviting them to his party.
Patrick is more extreme. For example, he can short-circuit his brain at random. Taken past the logic extreme in one episode where he FORGETS HOW TO BREATHE!. "I'm With Stupid" mentions Patrick also forgot how to eat at one point.
In "Gary Takes a Bath", SpongeBob paints the bathtub like a treasure chest, which he leads Gary to as if on a treasure hunt. SpongeBob hands Gary bars of soap, calling them doubloons, then promptly warns Gary not to drop them.
This exchange in "Grandma's Kisses":
Patrick: Then you get behind her and I'll push! SpongeBob: Patrick, we didn't say that.
There's also in the beginning of the episode "Your Shoe's Untied", where SpongeBob was watching a live-action sea anemone gyrating (thus implying that he was watching porn) until Gary meows, startling SpongeBob — who promptly changes the channel, claiming he was looking for football and admonishing Gary for telling lies.
The ending of "The Fry Cook Games":
Patrick: You know, these were white when I bought them. *He is wearing yellow underwear.*
In "Sandy, SpongeBob, and the Worm": "It was big, SCARY, and pink!" What else is big, scary, and pink?
Dressed to Plunder: In "Aargh!", Mr. Krabs goes treasure hunting with SpongeBob and Patrick dressed in fancy pirate captain duds, and gives his two underlings some pirate wear to match. SpongeBob puts on two peg legs and calls himself Peggy the Pirate, while Patrick wears eyepatches on both eyes as Blindbeard the Pirate.
Drill Sergeant Nasty: Mrs. Puff's substitute in one episode, and the warden of the prison island that SpongeBob and Patrick are stuck on in another.
Spongebob orders "A shot...of milk, two percent" at the Krusty Kantina, to which Squidward replies, "Think you can handle it?"
Dude, Not Funny!: In-Universe example: During "Fools in April", Squidward gets fed up with Spongebob's constant pranks, and decides to get revenge. He ends up taking his prank overboard, and ends up making him run out crying. The customers don't take kindly at all. However, their offended reaction to the prank was revealed to be just acting for ANOTHER April Fools joke.
Another example happens in "Ripped Pants" where SpongeBob gets the brilliant idea that pretending to drown makes a good segue to his ripped pants gag.
Dumb and Drummer: Patrick is the drummer for SpongeBob and the Hi-Seas, and was the drummer at the end of "Band Geeks". Earlier in the episode he played the trombone and SpongeBob played the drums.
Dumbass Has a Point: Patrick's rant in "Wet Painters" after he and Spongebob get a microscopic drop of paint on Mr. Krab's first dollar:
Patrick: This is all Mr. Krabs' fault! If he hadn't hung that stupid dollar in the first place!...I mean, it's not like it looks any different than a regular dollar. Why hang it? You could just stick any old dollar bill on the wall, no one would even know the difference!
In "Squidtastic Voyage", Partick actually says something smart, and everybody is surprised.
Dumb Muscle: Patrick has been shown on a few occasions to be fairly strong, though this is especially prominent in the games. He's not exactly the smartest guy around, either.
Earpiece Conversation: Patrick coaches SpongeBob through his boating test with a walkie-talkie hidden under a cowboy hat. Mrs. Puff compliments SpongeBob on his improvement, joking that it's as if someone were telling him all the answers. But when she mentions that that would be cheating, SpongeBob freaks out and confesses... and crashes the boat, failing the test once again.
Easy Amnesia: Played with in "Missing Identity", where SpongeBob suffers a "horrific incident of terror", yet came out alright — it was a missing nametag that drove the plot. For the rest of the episode he repeatedly reenacted his morning routine, complete with the aforementioned "horrific incident of terror". For "WhoBob WhatPants", the creators intentionally revisited the idea to play it straight.
Either/Or Title: All episodes have title cards, but some are presented within Patchy specials, most of which have titles themselves: "Shanghaied" is part of "You Wish" or "Patchy's Pick", "Party Pooper Pants" is part of "SpongeBob SquarePants House Party", "Ugh" is part of "SpongeBob SquarePants B.C. (Before Comedy)", "The Sponge Who Could Fly" is part of "SpongeBob SquarePants Lost Episode", and "Truth or Square" is part of "Patchy the Pirate's SpongeBob SquarePants Fan Club Big Time Impressive Celebratory Television Extravaganza!" Similarly, three episodes have Special Edition Titles that rename the show: "Christmas Who?" is The SpongeBob Christmas Special, "What Ever Happened to SpongeBob?" is WhoBob WhatPants, and "Hello Bikini Bottom!" is "SpongeBob On Tour".
Escalating War: The climax and ending of "Employee of the Month" has this, as Spongebob and Squidward use increasing abrasive and ludicrous ways of keeping each other from reaching the Krusty Krab—topping off with Squidward tied to a giant boat, and Spongebob tied to an anchor. Then when they reach the Krusty Krab, they wreak even more havoc as they tear it apart while cleaning in an attempt to impress Mr. Krabs, and then finally produce a pile of Krabby Patties so quickly and at such a fast rate that it causes the Krusty Krab to explode.
"Sand Castles In the Sand" starts with Spongebob crushing Patrick's sand castle, saying it did it wrong. To get even, Patrick does the same to a castle Sponge then builds. The whole episode is an Escalating War depicting the two trying to outdo each other with more complex sand castles and imagery. Eventually, they really get into it, building sand armies to demolish the other's castle. It culminates in an aerial dogfight complete with sand-nukes.
Even Beggars Won't Choose It: A guy who hasn't eaten for days crawls into the Krusty Krab begging for food, but when he gets offered some he rejects it because the Krusty Krab lacks "pizazz." He then crawls away still begging for food... water... atmosphere!
Squidward, although not evil, is a notorious Jerkass who hates SpongeBob with a passion. Even so, he was absolutely disgusted when Mr. Krabs sold SpongeBob's soul to the Flying Dutchman for pocket change.
Speaking of the Flying Dutchman, he himself was surprised that Mr. Krabs was not only eager to sell his soul and took the whole ordeal lightly. But he also sold his soul several times to other ghosts, monsters, and to SpongeBob (he was a bit short on pay day).
Another Squidward example happens in an episode where he and SpongeBob go on a pizza delivery. After the customer refused to accept the pizza, SpongeBob goes into a depression. Squidward, who usually enjoys seeing SpongeBob's misery, actually feels sorry for him, goes up to the customer, and slams the pizza into his face.
Even the Guys Want Him: When Squidward got his face reconstructed after getting in the way while SpongeBob was opening a door.
Everybody Knew Already: In "Banned in Bikini Bottom", when Mr. Krabs was forced to close down the Krusty Krab, he converts SpongeBob's house into a secret Krusty Krab... complete with a sign advertising it as such.
Everybody Laughs Ending: Parodied in the episode "Mermaid Man and Barnacle Boy V," which ends with every character featured on the episode laughing one after another, even characters with no reason to laugh, such as Manray and the Dirty Bubble, who are in prison, even though the only "joke" was that Barnacle Boy couldn't finish his Krabby Patty.
Subverted in a much later episode, "Spongicus". SpongeBob, Patrick, Krabs, and Squidward begin laughing as the music cue signals the end of the episode, but the scene continues. One by one, the characters get bored, stop laughing, and walk away.
Tattle-Tale Strangler: Get your feet out of my eye sockets! [screaming] SpongeBob: I'm trying— BUT MY CLEATS ARE STUCK IN YOUR CORNEAS!!! ...Six hours later...
Also in the episode where the krusty Krab gets a claw machine (which squidward fails at) and therefore cant pick anything up- so while watching tv- and cant pick up the remote- he changes the channel WITH HIS EYE- then proceeds to scream.
Eye Shock: Usually to either SpongeBob, Patrick, or Squidward.
Fan Of The Underdog: SpongeBob and Patrick seem to be the only entities in Bikini Bottom that actually like Squidward and consider him as wonderful and talented a being as he himself believes he is. Unfortunately their stupidity and clinginess still manages to cause him as much suffering and pain as everyone else's harshness.
SpongeBob: There are sharks in the water! Shark: Hey! That's my family you're talking about! SpongeBob: Um... sea monsters! Sea Monster: You know, we sea monsters have made great contributions to the fields of science and literature.
Also parodied in "Squirrel Jokes"
From Spongebob reading the dumpster writing in Sailor Mouth: "'Nematodes are people too!' (Dismissively) HA! Those nematodes!" Just replace nematodes with any minority group in the world and see how bad a person you suddenly feel.
To be fair, nematodes drank his house once.
Fantasy Twist: SpongeBob fantasizes about what his life would be like if he had muscles. It turns out to be exactly the same as it is now, but with muscles.
Flying Dutchman: Heard what you said? I couldn't hear myself thinking with this one around. I only had him for thirty seconds. And it's jellyfishing this and Mermaid Man that. Why, not giving him back is a fate worse than death He's your problem now.
Felony Misdemeanor: SpongeBob tends to overreact whenever he makes a single mistake during his job, like being late by a minute, accidentally giving a customer a large-sized soda instead of a medium one, being out of napkins…
To take this trope literally, do not litter in Bikini Bottom. Ever.
Feud Episode: Squidward gets SpongeBob and Patrick to stop being friends by sending them each his own makeshift bubblegrams. Once Squidward realizes what he did when both ex-friends want him to be his friend, he comes up with a plan to get them to be friends again.
Another thing that has been flanderized about Patrick is his snaggletoothed grin, in the early seasons he very rarely used it, in the later episodes he does this all the time to the point where it's practically his default smile.
Any and all aspects of Sandy's older "tough cow-girl" traits seem to have been completely removed until the episode "Rodeo Daze" in favor of her knack for building inventions...something she did ONE TIME in the first season.
Flat Character: Princess Mindy in The Movie. If you think about it, she's really not much more than a plot device. Her only contributions to the story were to be a love interest for Patrick, stop her father from killing Mr. Krabs, give SpongeBob and Patrick their "mustaches", and stall her father long enough for SpongeBob to come back with the crown.
Foil: SpongeBob to Squidward. SpongeBob is an idiot, but is well-meaning, and who is sort of pleasurable to be around. In contrast, Squidward is a smug, pessmistic character who hates his job, thinks he's superior to everyone else, and is the town's unofficial Butt Monkey.
Foreshadowing: In "I'm With Stupid", Patrick's parents are initially impressed that their son immediately recognizes them (their first line is, "Wow, son! You actually recognized us this time!"), and Patrick doesn't bother to defend himself. As it turns out, they're not his parents. Patrick doesn't realize this because, as hinted at, he frequently forgets what his real parents look like.
Forgot to Pay the Bill: Subverted. SpongeBob thinks Gary did this when the electricity goes out, but it was actually caused by the Blue Jellyfish cutting the wires.
May be more a case of Knight Templar or It Amused Me, since Krabs often sees Plankton as far more evil than himself and deserving of whatever torture he gives him (even when it's unprovoked).
Four Is Death: The episode Face Freeze includes a story of a man who stuck his tongue out at people 444 times, which prevented him from putting it back in. The number also foreshadows how grotesque the episode becomes.
Freak Out: Most of the characters have this at least once.
Freeze-Frame Bonus: In "No Free Rides", when Mrs. Puff enters her house, there's a painting of the EXACT same frame in the top left! And if you look closely, the painting has ITSELF in it!
The Friends Who Never Hang: Sandy is rarely involved in the antics going on at the Krusty Krab, so she's not seen interacting with Mr. Krabs or Squidward much individually, and is rarely placed against Plankton.
Fun with Flushing: SpongeBob and Patrick hear a story about a drain that two kids pulled long ago and that flushed away all of Bikini Bottom. They become obsessed with finding "The Big Drain" and making sure no one pulls it again. They do pull it but then it turns out to have been All Just a Dream.
Gainax Ending: In-universe: "I Had An Accident"'s ending results in a family staring through their TV at you in disbelief, shaking their heads, and turning it off.
Geographic Flexibility: Bikini Bottom is shown to be this. In most episodes it's a typical small town, but other episodes have shown that it contains a mall, a racetrack, and an Olympic stadium, among other things.
Giftedly Bad: Squidward is not as good at music as he thinks he is.
Gilligan Cut: In the episode "Idiot Box", Squidward doesn't understand why the cardboard box will make noises for SpongeBob and Patrick.
Squidward: Why won’t this thing turn on? All right, fine. If you don’t want to show me, I don’t care! I've got better things to do than pace the floor wondering how you two work this thing. (Cut to Squidward pacing the length of his living room floor) How do those two work that thing?! There's got to be a secret button or a switch or something!
Ambulance Cut: Subverted temporarily in the episode "Born Again Krabs". Mr. Krabs prepares to take a bite out of an old, filthy, tainted patty. Just as he is about to bite down on it, the shot cuts to an ambulance, implying that Krabs was now being rushed to the hospital. As it turns out, the ambulance was only passing by the Krusty Krab.
Mr. Krabs: Oh, look. An ambulance. Now then, where was I? (He takes a bite out of the patty, and the Trope is played straight afterwards.)
Hammerspace: In episode "Fear of a Krabby Patty," a frantic, delusional SpongeBob gives Plankton just enough time to squeak out, "Hey where'd you get that piano?" Just before, well, you know.
Plankton did one of these himself in a much earlier episode, "Plankton!", offering SpongeBob a golden spatula in an attempt to get a Krabby Patty from him. "I've been keeping it in my...secret compartment. SHING! Sparkle-sparkle."
In "FUN", he hid the Krabby Patty (which is bigger than his body) in his pocket.
Patrick: Is mayonnaise an instrument? Squidward: No, Patrick. Mayonnaise is not an instrument. (Patrick raises his hand) Squidward: Horseradish is not an instrument either. (Patrick puts his hand down)
Hanlon's Razor: Played rather straight with SpongeBob, he can get away with all kinds of travesties he commits on others, so long as he means well in his actions. Patrick fits the bill most of the time as well.
Hates Baths: An episode is devoted to Spongebob trying to get Gary to take a bath and failing.
Healing Factor: SpongeBob can repeatedly rip off his own arms, and they will sprout back in the same scene with no problems and no pain. May also explain the various Amusing Injuries. In fact, considering the supporting cast includes a starfish, a crab and a(n alleged) squid, this trope is Justified.
Word of God confirms that Squidward is in fact an octopus. In a commentary on The Movie DVD, he says that calling him "Octo-ward" didn't sound right, it was too difficult to animate him with eight legs, and early drafts that gave him the ability to produce ink...just didn't look right.
SpongeBob's healing factor is so powerful that there are several gags involving Spong Bob's arms or legs being ripped or broken off. One hilarious example is in the episode "The Graveyard Shift", where Mr. Krabs decides that the Krusty Krab will be open 24 hours a day. So Squidward and SpongeBob are stuck there all night. To pass the time, Squidward tells a scary story about the "Hash-Slinging Slasher". SpongeBob bites his nails...then chews his fingers off...then his arms are being fed into his Buzzsaw Jaw as soon as they regenerate...and then he eats a bucket of his arms like a bucket of popcorn.
I Thought Everyone Could Do That: When Squidward gets to the part where the Hash-Slinging Slasher cut off his own hand, SpongeBob doesn't react. In fact, he even demonstrates. Then Squidward explains that it didn't grow back, and suddenly SpongeBob is terrified.
He has another one in the episode where he escapes death, vows to turn over a new leaf, and thinks his massive generosity and debt is all a dream and he's still in the hospital. And then SpongeBob and Squidward tell him he checked out of the hospital and here's the bill.
Squidward also gets one near the end of "Squid's Visit".
SpongeBob gets one in Krusty Dogs when Mr. Krabs removes Krabby Patties from the menu.
Horror Doesn't Settle for Simple Tuesday: Subverted. In "Graveyard Shift" where Squidward's improvised ghost story says that the ghost of a former Krusty Krab employee visits the restaurant every Tuesday night.
Patrick: Look, SpongeBob, are you gonna listen to a big dummy, or are you gonna listen to me? SpongeBob:Umm...
From 'Pressure', while SpongeBob and the others were laughing at Sandy's failed attempt to breathe underwater:
Mr. Krabs: I knew it! There was no way some "airhead" was gonna win anything against a water breather! Patrick: Airhead... (Laughs. The top of his head deflates like a balloon) Huh? (Puts thumb in mouth and blows. His head becomes round at the top.)
Same episode, while Sandy is telling the other four to go on dry land already :
Sandy: Well? So are you going or not? SpongeBob: Actually, you know, but... Squidward: We can't, uh...because... Mr. Krabs: Well, um... we're late for our... Patrick: Our fitting! Sandy: Oh, you mean for your chicken costumes? Patrick:(Holding and eating popcorn) Hey, we are not chicken! (Drops popcorn) (Gasps) My popcorn! (Begins pecking at it like a chicken)
From "Party Pooper Pants", while Patchy remarks that he hopes SpongeBob received his invitation for his party:
Patchy: Welcome! Say, you didn't bring SpongeBob with you, did you? I sure hope he got his invitation. (cut to SpongeBob and Patrick) SpongeBob: I'd sure like to go to this party, but I can't read the invitation! (Shows close-up of the invitation revealing that the print is sogged and ruined) Patrick: Me neither. SpongeBob:(Examines invitation) Whoever sent this obviously has no idea about the physical limitations of life underwater! Well, might as well throw these in the fire. (Scene zooms out revealing a bonfire between SpongeBob and Patrick. Both throw their invitations in the fire)
From 'Squilliam Returns', when Squidward told SpongeBob to empty his mind and his mind has various SpongeBobs emptying his mind:
Patrick in "I'm With Stupid", after trying to convince his parents that SpongeBob is an idiot to outshadow his own idiotic tendencies, only for his own stupidity to convince him that SpongeBob really is an idiot, leading him to insult and talk down on him in the most condescending manner, ultimately leading to:
Patrick: Oh, SpongeBob. Dumb people are always blissfully unaware to how dumb they really are... (Stares vacantly and drools)
And it's revealed in the end the couple Patrick introduced to Spongebob weren't Patrick's parents but the three stars were too dumb to notice until the real parents appeared.
From "The Camping Episode"
Squidward That is the stupidest thing I've ever heard!
Patrick Well maybe it is stupid, but it's also dumb.
From "Mermaid Man Begins":
Spongebob and Patrick: Squidward! Squidward! Let us in! We're missing the Mermaid Man marathon!
Squidward: Go away! I've got better things to do than watch grown men prance around in ridiculous outfits. (Cut to a man dancing ballet on Squidward's TV)
In the episode "Yours, Mine, and Mine", Patrick at the end says that Spongebob has learned nothing about sharing, even though we see him take Spongebob's wallet twice in the episode, and doesn't share the Krabby Patty toy with Spongebob throughout the whole episode, to the point that Patrick eats the toy so he won't have to share it with Spongebob! Let's face it. Patrick was more of a jerk in this episode.
"Little Yellow Book" features everyone laughing at SpongeBob's expense as Squidward reads his diary and its embarrassing secrets. They are disgusted with Squidward when SpongeBob runs away crying, but hey, they all knew who they were laughing at in the first place. Made even worse when Squidward points out that Patrick also read the diary, only for Patrick to dismiss him as "blaming everyone else".
Identical Stranger: In "No Weenies Allowed": a sponge identical to SpongeBob only with dark hair and the real deal (wearing a Rainbow Clown Wig) both appear at the Salty Spittoon at the same time.
In a later episode, Spongebob tries to infiltrate Pearl's slumber party by going in disguise. It then shows a female sponge from "Farawayville" who just so happens to want to join Pearl's party, and is rejected. Turns out that was not Spongebob in disguise, as when she runs away from the party in tears, it shows Spongebob disguised with a mustache. He remarks that the girl is "uug-lee!"
Incessant Music Madness: In "Jellyfish Jam", SpongeBob and a jellyfish keep Squidward up all night playing loud music. When more jellyfish show up and play the music even louder, Squidward has had enough and counterattacks by playing his clarinet. This angers the jellyfish, and when SpongeBob's pleas to stop result in Squidward playing even louder, the jellyfish goes over to Squidward's and stings him.
Incredibly Lame Fun: SpongeBob and Patrick once play a game that consists of doing, well, whatever non-sequitur goes through their minds, like climbing a coral to make bubbles to determine a chess move, and make that move by blowing at the chess piece.
There's another scene where Mr. Krabs hangs out with SpongeBob and Patrick because he feels old. They end up going to the laundromat, reading at the library, sitting in a kiddie pool, et cetera. Subverted at the end when they suggest a panty raid. THAT is subverted when it turns out to be Mr. Krabs's mother's undergarments...
SpongeBob and Patrick once buy a large TV so they can play inside the box. They use their imagination to enjoy it so much, Squidwards wants in.
Subverted on another occasion, SpongeBob gets a "useless" piece of paper from Squidward and then uses it to play all sort of games and use it to swim/fly around.
Incredibly Lame Pun: SpongeBob and Patrick argue back and forth with these in Pranks-A-Lot, until they are interrupted with the narrator saying "Several bad puns later...".
SpongeBob lets loose a stream of them towards the end of Gary's Bath.
Injury Bookend: Played with. Squidward gets hit in the face by a door, and the resulting alteration to his bone structure causes him to become ridiculously handsome, so much as to attract copious amounts of attention from both men and women. After becoming overwhelmed with his newfound status, he attempts to become normal again, getting hit in the face with the same door several times again. This just makes him even more beautiful, however, only going back to normal after getting hit in the face with a pole after running to avoid a falling shoe.
Mrs. Puff's actress is Mrs. Puff if she weren't an anthropomorphic fish.
Flats the Flounder is the same character he played in another movie. By the amount of times he says butt in the episode, you can tell he wants to add 'head' to the end of it. Flats's voice actor also voices the impostor father of Patrick in one episode. Add the irony of that character being called Marty...
Inner Monologue Conversation: In "Big Pink Loser", Patrick is imitating everything SpongeBob says and does. SpongeBob thinks (At least I'm safe inside my mind), then hears Patrick thinking the same thing.
Innocently Insensitive: Spongebob and occasionally Patrick have moments of this, especially around Squidward. Case in point this compliment to Squidward's clarinet playing, said with completely sincere enthusiasm:
Spongebob: Bravo, Squidward! And all those wrong notes made it sound unique.
Squidward: Wha?...There weren't any loose notes!!!
Innocent Swearing: In "Sailor Mouth", SpongeBob and Patrick read a bad word written in a trash bin and start using it. Patrick claims it's a "sentence enhancer".
Interspecies Adoption: One episode focuses on Spongebob and Patrick adopting a baby scallop and taking care of it. The sight of a male sponge and male starfish being parents to a scallop leaves other citizens of Bikini Bottom a little more than confused on how it's even possible.
When he's not the one causing the abuse, SpongeBob himself.
Ironic Echo: In One Krab's Trash. Krabs goes to the cemetery to find Smitty Werbenjagermanjensen's grave and take back his hat. He sees Squidward laying down flowers on a grave, which reads "Here Lies Squidward's Hopes and Dreams." Krabs remarks "what a baby." Later, when Krabs finds out that the hat is now worthless, he breaks down in tears, and a flower carrying Squidward walks in the background, pausing to say "what a baby."
In "Squidville", Squidward snobbishly asks what's so fun about playing with a reef blower. SpongeBob and Patrick reply, "It's fun!" Squidward says: "How can you possibly have fun with one of those over-sized hair dryers?" SpongeBob and Patrick proceed to show him by sucking up his window with the reef blower. Later in the episode, when Squidward begins to tire of Squidville, he plays with an abandoned reef blower and two spectators ask him what's so fun about playing with a reef blower. And, you know the rest.
