Hugh Neutron also seems to be one. His obsession with ducks and pies is just the start.
A very large proportion of the cast of Adventure Time. Some individuals stand out in particular.
The people of Lumpy Space (especially Lumpy Space Princess) seem to abandon all shreds of sanity when they "turn lumpy."
Tree Trunks attempts to have tea with and seduce monsters (Tentacle monsters) when they attack her. Finn and Jake seem to consider Tree Trunks's idiosyncrasies to be due to senility, however.
Ice King later turns out to be a rather horrifying deconstruction of this trope. His strange behaviour actually stems from having had his mind warped and his memory erased by an Artifact of Doom. The process was slow and extremely painful, destroying his relationships with his fiancee and surrogate daughter, and it's implied that most of his actions are a subconscious attempt to replace them. By the time the main series takes place, he's barely a shadow of his old self and is miserable due to his inability to form normal relationships. And, it's implied that without the mental remnants of his old self restraining him, he would be just a violent madman rather than an ineffectualCloud Cuckoo Lander. When this control occasionally slips, he is much moredisturbing.
The entire Banana family (especially Banana Joe) seem to lose all contact with reality when they get excited, scared, or angry.
Richard goes right up to many strangers and hugs them, thinking that will make them like him. This is justified because he has been over-sheltered by his mother, however.
Sussie takes this trope Up to Eleven. Her eccentric behavior is actually merely how she wants to live her life. To her, the meaning of life is enjoying it in any way possible, and acting bizarre is her way of doing so. That explains a lot. It's also heavily implied that it comes from her being dropped as a baby. Before that she was a Wise Beyond Her YearsChild Prodigy.
Spud from American Dragon: Jake Long does have a case of Obfuscating Stupidity (mainly to cover up that he's actually a genius), but that doesn't mean his head isn't in the clouds regardless. One episode has Jake read his mind, so the audience knows he wasn't faking anything.
Spud:No matter where you go, if you try to hide, the moon will always find you.
Professor Rotwood. Sure, he's the only character on the show who's figured out there's something supernatural going on and he eventually does find out who Jake is, but from his dialogue he's definitely a little loose up there. Such as this one time where Jake turned in his own scales and clippings from his claws to get money from Rotwood, and this exchange happened.
Rotwood: Everyone knows that dragon claws glow in the dark, and their scales have the faintest odor of lavender. Jake: You wouldn't know a dragon if it took a bite out of your butt! Rotwood: You flaunt your innocence, Mr. Long. Dragons have acute allergies to human buttockses.
Yakko, Wakko, and Dot from Animaniacs takes this trope to extremes, as even their theme song is filled with non-sequiturs and bizarre references. Wakko, however, seems to be the most extreme of the three. In one episode where the kids visit a shopping mall, he walks the wrong way on an escalator and declares "Mine's broken." Yakko explains it as "middle kid syndrome." Also, Wakko has a pseudo-Liverpudlian accent for no apparent reason (something his brother and sister don't have). It's because Wakko's voice actor, Jess Harnell, was a fan of The Beatles. He chose to imitate Ringo because Wakko is the shortest of the Warner siblings.
This is also played up to a degree in the Spanish dub, in which, just as inexplicable as his Liverpudlian accent in the English version, Wakko is voiced by a woman (Giset Blanco), who not only gave him a feminine voice, but one that is also rather inconsistent. Sometimes, he sounds low and hoarse; other times, he's nasally; still other times, he's very high pitched.
Master Shake from Aqua Teen Hunger Force is selfish to the point of absurdity, and justifies himself with reasons that seem natural only to him ("I should not walk, so that a child may live... well, that's what it does!"). He also shows a profound gift for jumping to conclusions — e.g. convincing himself that a threatening cell-phone call is not coming from inside the ominous bus parked at the curb, but from the bus itself, and that the bus wasn't a bus, but a reverse vampire, which craves the sun. The tires are the markings. Lampshaded later, after a standard Master Shake random association session:
Frylock:What's your point? Shake:I never had one. And that makes you crazy, doesn't it?
Meatwad is ready to believe anything he's told. Or anything he's told himself.
Meatwad: I ain't got no job, my wife left me, bills pilin' up, I got child support payments, and I don't know if any of what I just said is true, but I believe it.
The robotic ghost of Christmas past from the future is always telling random irrelevant and incomprehensible stories that begin with words like "One Christmas billions of Christmasses ago, there was a...."
Cheryl from Archer recently spent most of "Viscous Coupling" thinking she was in Opposite World.
Dr. Krieger, the series' resident Mad Scientist, is dating a hologram and creates Fort Kick-ass out of cardboard boxes to escape the rest of the ISIS staff.
Krieger: I'm sorry, are you addressing me? Because your authority is not recognized in Fort Kick-ass!
While in said fort, he prepares and serves margaritas with blended bits of Cyril's destroyed cell phone.
Krieger: The secret ingredient is phone!
When the staff is deciding to unionize or not, after the anti-union talk is given:
Ty Lee: Hey, look at that dust cloud. It's so... poofy... Poof.
There's also the "nomads" in "The Cave of Two Lovers":
Chong: We're nomads, happy to go wherever the wind takes us! Aang: You guys are nomads? That's great! I'm a nomad. Chong: Hey, me too. Aang: I know... you just said that. Chong: Oh. (looks at Sokka) Nice underwear.
Even Aang had some slight moments of this earlier in the series.
Sokka: What's wrong with you, we don't have time for games with the war going on! Aang: What war? Sokka: You're kidding, right? Aang: PENGUIN!!!!!!! [runs off after a penguin]
While Sokka is normally pretty rational, he does occasionally have some very strange ideas, such as when Momo goes missing, Sokka concludes, apropos of nothing, that Appa ate him, and attempts to crawl into Appa's mouth. And at another time he licks something off a cave wall, despite having just spent a whole day hallucinating thanks to going bonkers from cactus juice, because he has "a natural curiosity".
Beavis And Butthead, but especially Beavis. Beavis even sometimes takes on a separate identity (which personifies this trope even more than ordinary Beavis) when he consumes large amounts of sugar or caffeine.
Beavis: I am the Great Cornholio! I need TP for my bunghole!
Tilly Green of Big City Greens lives by the beat of her own drum. This is a girl who once entered a goat into a dog show because she claimed it had the soul of a dog!
Eddie Storkowitz from Birdz doesn't always have the best grip on what's reality and what's fiction (see "I Heard It Through the Grapevine"). He's also prone to flights of fancy and daydreaming.
Mr. Nuthatch from the same series evolves from a paranoid wreck to a happy, confident but very eccentric bird (in one episode, he enters the psychiatrist's office through the heat vent for no reason).
Bob's Burgers: While all three of the Belcher kids are pretty out there, Gene takes the cake with his outlandish ideas, short attention span, and Attention Whore tendencies.
For an insanely politically incorrect character, Uncle Ruckus from The Boondocks manages to come off as this. It was revealed in his back story The Color Ruckus that his Cloudcuckoolander tendencies were enforced by a Hilariously Abusive Childhood (though part of it was played straight, so its hard to say how "hilarious") and his mother's indulgent cultivation of a fantasy that he was actually white. This built him into a self-hating black man who bounces back and forth on whether he knows he's black or truly believes he's white, and just happens to have a skin condition called "Revitiligo" (the opposite of Michael Jackson) that makes his skin darker. His views on race relations and his politics are thus incredibly bizarre, even by the looser standards of the Boondocks universe. What helps is that sometimes his warped view of reality wills out, as in the season four episode Early Bird Special where his solution to getting rid of a clingy, middle-aged black woman who had become attached to Robert was by introducing a submissive middle-aged white woman, causing the black woman to storm off.
Brak's Dad from The Brak Show. Frequently he gives little Leave It to Beaver style father-dad chats with Brak at the end of the episodes where he recounts the details of the lessons that Brak should have learned from the events of the episodes, except that they are completely incomprehensible.
Brak himself, for that matter. His response to being told Mr. Thundercleese will tear his arms off for killing off Thundercleese's goldfish is to moan "But I love my arms! That's where my hands live!"
Numbuh Three from Codename: Kids Next Door. This is not to say that she's any less of an asset to Sector V than the rest of her teammates; in "Operation: M.A.C.A.R.R.O.N.I." She was able to beat up Mr. Boss (one of the two Big Bads of the series) by herself. (She does have a sort of Unstoppable Rage quality, which helps.)
In The Critic, Jay Sherman's father Franklin is a very much a 'Lander. Among other things, Franklin has been shown to see the world as a game of "Donkey Kong", imagined himself to be Quick Draw McGraw's alter-ego El Kabong and requested that President Bush Sr. make him "Secretary of Balloon Doggies" (later insisting that the balloon doggies demanded it). When Jay went missing temporarily, Franklin set up a press conference — so he could announce that if he could be any type of vegetable, he'd be a carrot.
He also claimed to be the first black female head of the Ku Klux Klan, invented the "fishbabywhirlmajig", imprinted on a goose and followed her, quacking.
He was originally one of America's greatest minds, but had never had a drop of alcohol. One taste, and he was Larry Fine.
By the way, according to Franklin, his fishbabywhirlmajig "will be bigger than the Badger Blaster!"
In his recollection of his and Eleanor's first date plays out like a Popeyecartoon.
Jay Sherman: (Confused) I don't get it.
Franklin Sherman: (Smiling warmly) Neither do I.
One time he was asked why he had a banana in his ear his response "I'm trying to lure out the monkey who lives inside my head."
After his butler is hired away by a new neighbor, Franklin keeps the silverware and the dog safe by gluing them to the ceiling.
"Well, there's Marty on the TV. ... Just reach in and pull him out. That's how I met the Fonz."
Ditzy in The Crumpets is an optimistic and dreamy girl with a somewhat poor judgment (such as making an Immediate Self-Contradiction) and is interested with religion and spiritualism. Heck, her head is a balloon (making her a literal airhead) which was officially described to prefer being in the clouds, and her bedroom is cloud themed.
Also her father Pa. He is a gardener who uses plant-based language, obsessed with nature and likes living in a more natural lifestyle (no videogames, artificial chemicals, or even a tent during a trip to the woods) which is sometimes against the will of his family.
Allie on the PBS Curious George to some degree. When George first meets her, he finds her in a bin with several chickens, which she emerges from, saying that now she knows what it's like to be a chicken and she doesn't recommend it because it's very boring. The narrator even states that George had seen a lot of strange things in his life, but this was new to him.
Daffy Duck. Especially prominent in earlier shorts (though even his later, more egotistical persona isn't all that stable).
Daffy: WOO, HOO!!! HOO, HOO!!!
The Davincibles: Leo Davinci. Just to name a few of his quirks: he is a Man Child, who doesnt hesitate a moment to drag his niece and nephew into his adventures, is not the brightest bulb on the tree, can easily get hyperactive and carried away when pursuing a new relic, and doesnt really know much about antiques despite running an antique store.
In the Defenders of the Earth episode "The Would-be Defender", the Defenders meet Earl Sump, a teenaged boy who's obsessed with comic books but has little idea what being a Defender really involves.
Dee Dee from Dexter's Laboratory was born in Cuckooland, sometimes leaning more to The Ditz, but, in other cases, just a Cloudcuckolander. It is especially evident when she tells Dexter her bedtime story while she's sick, mixing a variety of common childhood nursery rhymes and stories.
Unlike the comic strip, which varies week-by-week, the Pointy-Haired Boss in the Dilbert cartoon is consistently a Cloudcuckoolander, to the point where it often overshadows his Mean Boss tendencies.
Mad Scientist Urpgor of The Dreamstone plays with this, since while he is completely and utterly nuts, he also often acts as an Only Sane Man to the other Urpneys' stupidity. Sgt Blob and Nug have shades of this trope as well, even if they are much more lucid. Rufus is a more mundane example Depending on the Writer.
Jonny 2x4, whose best friend is a wooden plank with a crude face drawn on it, is also an apparent expatriate of Cloudcuckooland. Taken to the extreme in "Shoo Ed", where he acts crazier than normal.
"I'm the bike pixie! Catch me if you can!"
Ed might have left Cloudcuckooland the same day...
Ed: Yeah, Double-D, an elephant never forgets, but I forgot what the elephant remembered.
Rolf, the wacky foreigner, says weird things all the time and his culture has some very strange customs.
Cosmo and Crocker from The Fairly Oddparents While Cosmo's just that odd, Crocker's gone mad from losing his fariy god parents (coincidentally, his fairy god parents were Cosmo and Wanda, and it was Cosmo's fault Crocker lost them in the first place).
Many characters on Family Guy, especiallyMayor Adam West. West brings his own creamed corn to the theater because the creamed corn they have there is too crunchy. He once dispatched the entire Quahog police force to Colombia to rescue the heroes of Romancing the Stone. He chases people off his property with a Cat Launcher.
Adam West: My God! Someone's stealing my water! Meg: But it just went down the drain. Adam West: They hit when you least expect it.
His strategy to distract people from the "Dig'Em" scandal—jingle keys from his window. Then he gets hit by someone throwing a brick and starts to bleed.
Peter also has to qualify. He once forgot how to sit down. He was convinced he could speak Italian just because he had a moustache.
Ferret from Scott Morse's cartoon short Ferret And Parrot who falls in love with a comic strip character named Yolanda The Aardvark.
In Fillmore!, there's O'Farrell. Let's put it this way: X Middle School is a place where the taffy-sellers are running a protection racket, the librarian gets so caught up in a Mark Twain book that he doesn't notice the entire library being borrowed under fake ID's, and a graffiti artist is kept in a state of permanent detention with his lessons piped in through CCTV...and O'Farrell still comes across as the resident eccentric.
Bloo's insane theories, Madame Foster's strange actions and speech patterns, Coco's occasional inexplicable behavior, Cheese's spastic jabbering and Goo's... entire personality. Most of them are products of the fertile imaginations of young children.
It's implied that Goo's parents may be the same, since they were unwilling to rein in her imagination (in spite of the fact that it regularly produced hundreds of imaginary friends) and apparently allowed her to name herself shortly after she was born (Goo claims her name is short for "Goo-goo-ga-ga").
The title character from Freakazoid!. A lot of his actions and dialogue are really bizarre.
Xander Crews from Frisky Dingo is a good example, mainly because he lives in his own world without consequence, eventually adopting the alias of Barnaby Jones when he gets in trouble, and generally says ridiculous things
Killface: This is hopeless. Xander: Look, don't worry man. At his age, I was like, chronic masturbater. Kinda, kinda still am. But the point is — I like it. I would like to masturbate right now in this car. You know? If I had my stuff with me. I would! What are we even talking about? Killface: I'm talking about searching for Simon! Xander: Oh.
Wendell also very much qualifies, with his habit of throwing non-sequitors into his conversations and his...interesting thoughts on sex.
Bus Salesman: You're a man who knows what he wants. I'll bet the ladies like that. Wendell: Oh, yeah! Ol' Wendell's dragged the ol' pineapple through quite a number of ladies.
Killface: Wendell, you've outdone yourself! Wendell: Well, now I know how Diego Rivera must have felt when he was banging Frida Kahlo. (beat) Tea bagging the unibrow. (Extended beat)
Gypsy: Well, there is perhaps one way. Have you ever heard of the monks of Deshuba? Fry:(in a tone that suggests he thinks that this is the next best option) I've... not heard of them.
He is presented with a seemingly self-evident conclusion.
Leela: Superheroes cause a lot of collateral damage, and we don't wanna get our butts sued. Fry: Or do we...? (long beat while he thinks about it) No, I guess not.
He thinks he's being asked a question:
Leela:(feeding her pet) Aww... somebody likes snouts! Fry:(overhearing) Is it me?
He tries to explain something:
Fry: It's just like the story of the grasshopper and the octopus. All year long, the grasshopper kept burying acorns for the winter, while the octopus mooched off his girlfriend and watched TV. But then the winter came and the grasshopper died and the octopus ate all his acorns. And also he got a racecar. Is any of this getting through to you?
He tries to formulate a plan:
Fry: Okay, I've gotta break down that gate, beat up those three guards, steal that chopper and rescue Bender. (Leela beats up the guards) Fry: Yay, I did it! ...Wait, that's not me!
He's finishing a story:
Fry: ... So then, I unfroze myself, and then I came over here, and then I told you the story, and then it was now... and then I don't know what happened!
He's just trying to complete a sentence:
Fry: I'll be whoever I wanna do.
In the episode "Bendin' In The Wind" Fry finds a Voltzwagen with two centuries-dead skeletons in it. Not only does he bring the VW back to Planet Express headquarters, on his way back he takes the blue headband of one of the hippy skeletons and wears it himself for the rest of the episode. While there's nothing wrong with this, it's certainly not something a normal person would do.
Professor Hubert Farnsworth. It's supposedly justified by his senility and being a mad scientist. When he was speaking at the stockholders' meeting:
Farnsworth: Where am I?
Hermes: Move forward. Walk into the light.
Farnsworth: Oh God! I'm dead. Well, no matter. (pulls out cue cards) Thank you all for coming. I don't recognize any of you, nor can I recall why I am here. Now without further ado, a film highlighting Planet Express Inc.'s latest fiscal year.
He's clearly insane in any universe:
Farnsworth: Say, I hope you won't think it evil of me to ask how you got that stylish head wound?
Opposite Farnsworth: Oh, this old thing? I was experimenting to see if I could remove my own brain.
Farnsworth: Of course! I had the same idea! I flipped a coin to decide if I should proceed, but it came up tails, so I didn't. How'd it go?
Opposite Farnsworth: Well, getting the brain out was the easy part. The hard part was getting the brain out! (insane laugh)
Farnsworth:(chuckling) Oh, you.
Not exactly surprising, considering he and Fry are both related.
Farnsworth: ...Oh, they say madness runs in our family. Some even call me mad. And why? Because I dared to dream of my own race of atomic monsters! Atomic supermen with octagonal shaped bodies that suck blood out of... (trails off after leaving the room)
Zoidberg is neck and neck in the running with Fry when it comes to this trope. Which makes sense, what with him being the token alien and Fry having a unique form of brain damage. His introduction scene shows him coming right out the gate with this trope in full force.
Mabel Pines is enthusiastic about everything ("Yay, grass!"), prone to outbursts of silliness (like folding an encoded map into a paper hat), and full of ridiculous ideas for arts and crafts projects (from her hundreds of hand-knitted sweaters to stuff like "caticatures" or a drawing of "a waffle with big arms"), but she and her brother Dipper are savvy enough to cope with the weirdness endemic to the eponymous town.
Topping them all, however, is town founder and 8th-and-a-half President of the United States, Sir Lord Quentin Trembley III Esq., who, as seen in "Irrational Treasure", declared war on pancakes, outlawed pants, and appointed babies to the Supreme Court. He's also still president because he was, for lack of a better word, "elected" before the two term limit was imposed and also because:
Dipper: Quentin, did you ever sign an official resignation? Quentin: No, sir! I ate a salamander and jumped out the window!
Several of the characters from The Grim Adventures of Billy & Mandy could be said to fit this trope - including the titular Billy. But hands down the Cuckoolander Champeen is Eris. Of course, her excuse is that she's *literally* the Goddess of Chaos, and it's both her job and her reason for being to spread it.
Foo. He once thought he needed to take his pants off to ride a bike, and then there's this below.
Kratz: Why is Foo wearing a sweater over his head?
Foo: It's slimming!
Piri Piri has Foo beat by a mile. She's an artist who gets her inspiration from her dreams, says her favorite color is "innocent baby laughter", claims to have learnt the language of trees in a dream, and frequently makes non-sequitur statements about life and the universe in the most cheerful manner.
Phil Ken Sebben must have gotten his license to practice law from the Cloudcuckooland bar. Aside from prefacing everyDouble Entendre with "HA HA!", he once believed furniture he didn't actually have was being stolen, causing him to issue "threat warnings" consisting of such levels as "Blackwatch Plaid" and "Rush's seminal Moving Pictures album." He also has an arsenal of guns in his office, each labeled for a specific threat that might require it's use, ranging from "Elephant Gun" to "Creature of Indeterminate Origin Gun."
Peanut, Birdman's clerk, definitely qualifies. It's often unclear if he's paying attention to what is going on, not helped by the fact that he is often mumbling in some other language.
It may be better to list the characters on Harvey Birdman who aren't Cloudcukoolanders. The wall. Hey, that was easy.
Arnold's grandmother on Hey Arnold! was ridiculous to the point of dressing up as Mary, Queen of Scots to go downstairs to the dinner table. Indeed, her Cloudcuckoolander status was so central to her character that in one episode, which was about a heat wave, it was so hot that it made her sane.
It should be noted that grandma Gertie might not be as mental as she appears, as seen during a very sane moment in "Parent's Day."
Arnold's cousin Arnie, known for collecting gum and reading ingredients on labels.
Hurra, whose logic appears to be dominated by his wacky imagination.
His girlfriend, Kinga the kangaroo, is much more extreme example. She lives with her Imaginary Friend, a potted flower named Adelka and spends most of her free time trying to make Adelka entertained (she takes her to cinema and ice skating or throws her birthday parties to which she invites half of the town...) Kinga also appears to be the most manchildish of all the characters on the show, and usually interpretates everything with her own bizarre logic.
On Holly Hobbie and Friends, Holly Hobbie's friend Amy Morris comes across very much as being on Cloud Cuckooland at times, often blurting out bizarre suggestions, such as the excuse for Holly losing her voice in Christmas Wishes being that she had a "freak scarf accident."
The Hollow: The way the Weird Guy acts and talks makes it pretty clear that he needs a check-up from the neck up.
If one were to examine GIR, one would inevitably find a "Made in Cloudcuckooland" label. Seriously. This guy could give Osaka a run for her money if not win outright. On one memorable occasion where we got to see the world from his point of view, a quartet of cows became talking sausages with top hats, canes and dinner jackets, which propositioned GIR to dance with them "into oblivion." Seriously.
Zim himself often fits; in one episode, when confronted by fully mobile talking babies (possibly a hideous parody of Rugrats), he stated that 'I knew it! Earth babies come from space!'. More pointedly, in an unfinished episode called "The Trial", he is kidnapped and brought to court among his people; in spite of the flagrant evidence that it is, in fact, a trial for his continued right to exist, he insists on believing it to be a party in his honor. In what was to be that episode's ending, Zim is scanned for defects by the robot "control-brains" that run the planet. His insanity drives the machines to madness, and they declare him the greatest of all Irkens. The Tallest weep as Zim is temporarily placed in command of the Tallest's ship and proceeds to smash it into everything.
Dib arguably qualifies in the later episodes of the show — what with randomly yelling "I AM DIB!" (a habit he seemed to pick up from Zim), and "How could I not have noticed this — me, the obsessive-compulsive DIB!"
Buford from the animated version of Jacob Two-Two is definitely this, although the rest of his family might be even worse: He has a cousin who thinks he's a goat, and an uncle who thinks he is...some sort of Beast Man. They had to call an exterminator to get the him out of the house. Jacob's dad enjoys hearing about Buford's family, because it makes his own family seem so normal and well-adjusted by comparison.
Beezy's girlfriend Saffi. Her dialogue consists almost entirely of random words like "Smoothy smooth!" and "Yogurt!", while her behavior includes things like eating tires and shoes or smashing any statues she sees. She's shown to be able to speak and act perfectly like a civilized person; she just chooses to act like a crazy animal.
The Question has his bizarre moments in Justice League, doing everything from going through everyone's garbage to believing in an over-arching conspiracy involving boy bands and Starbucks. Most of the time he seems completely insane and dangerously paranoid, but when push comes to shove on his theories, he's often proven right.
"A-HA! I knew it! They have thirty-two flavors!"
Trickster falls in here as well (notably, the "Bilateral symmetry" bit), but only when, as Flash points out, he's off his meds.
Stumpy. He's completely crazy, and comes up with the craziest reasons for everything.
Kaeloo is normally in constant bliss, is completely unaware of her surroundings and comes up with completely inaccurate judgements of situations. Mr. Cat is running a scam where he blatantly abuses Quack Quack and forces him to participate against his will? Quack Quack must be helping Mr. Cat!
Ron Stoppable of Kim Possible is a prime example. He marches to his own drummer and generally does some very odd things. He also has exhibited several instances of The Cuckoolander Was Right where he will come up with some off-the-wall supposition about what is actually happening, which other characters will scoff at.
Bobby. The boy fell in love with a wig dummy! To name just one instance.
Dale Gribble. Bobby at least has shown that he can competently conduct himself through many situations (his Cloudcuckoolander moments seem to be sort of self-aware instances of fantasy-indulgence, or the fact that he's still very impressionable as a child). Dale, however, seems to live quite happily as an adult in a world all his own that just happens to intersect with Arlen, Texas. Once he tried to combat a heatwave by "fighting fire with fire," which entailed turning the heat all the way up in his house. Another time he hosted his own shortwave radio show during which he claimed to be getting a phone call from former (and long-since deceased) Soviet Premier Leonid Brezhnev.
Chomper of The Land Before Time has somewhat become this in the TV series, from offering his friends insects to eat when they are herbivores to being surprised when being told that adults were hatchlings once.
As a result of people complaining that Bugs's Space Jam girlfriend, Lola, wasn't looney enough, The Looney Tunes Show made her a complete unmitigated nutcase. In the episode "Father Figure" it is revealed that she gets it from her father.
Len from Ruby Gloom fits this trope very well. He is known for being dumb and missing the point of almost all jokes, analogies, ect. He makes odd mistakes, such as mixing up irony and onomatopoeia. He is also shown to have odd and silly traits, like enjoying peanut butter and egg sandwiches. He's oblivious, often missing the obvious, and doesn't make good decisions.
Leni Loud from The Loud House is a sweet-natured Dumb Blonde whose train of thought goes to some very odd places at times. In "Left in the Dark", she thought she'd gone blind when she just forgot to open her eyes, and when Lynn tries to teach her martial arts in "Lock 'n' Loud", Leni tries flirting with the training dummy.
Charlotte from Making Fiends. She is oblivious to the horrors created by Vendetta, who she thinks is her best friend, despite the strong hints that Vendetta hates her. Charlotte also likes lemon drops, puppies, singing about monkeys and cheese. The apple doesn't fall far from the tree because she takes after her grandmother Charlene.
Zack: ...Okay, next time, key first, tap-dancing later.
The same show features Vinnie Dakota, a 70s-esque time-traveler who wears a track suit for no particular reason and is fascinated by lava lamps and foods inside other foods.
Cavendish: How can you be so out of shape? You're wearing a tracksuit!
Dakota: Well, you're wearing a top hat, how can you be so, I don't know, out of rabbits.
Miraculous Ladybug: Lê Chiến Kim tends to exhibit bizarre logic and little common sense. For instance, he puts on his swim trunks while going under the ocean in a train, claims he can outrun a panther, and manages to be totally oblivious to an akuma attack because he's swimming in Adrien's bathtub.
Texas on Motorcity. He's not very intelligent, but that's not his reason for being this trope. He's very hyper and immature (despite being presumably the oldest of the Burners besides Jacob). He often calls Julie by the wrong name. He comes up with these crazy ideas (which probably wouldn't work, hence the other Burners' reluctance to try them out). He is very delusional as well, as evidenced by an episode where he believes he was responsible for all the great ideas caused by Mike Chilton.
Mr. Bogus also counts as another prime example of this trope. Well, what would you expect from a three-inch tall gremlin who routinely gets himself into trouble?
Crystal Zilla of My Dad the Rock Star is a Pink-haired New Agey sort of Cloudcuckoolander, who is also Closer to Earth on occasion. But she's a mother, and her husband is rock star, so maybe it's a defense mechanism.
Spike: You know, Pinkie; these two ponies have a bit of a grudge match they're trying to settle, trying to prove who's the most athletic. Pinkie:Yes! And "grudge" rhymes with "fudge"! Spike: Yes it... does... What? Pinkie: And I like fudge. But if I eat too much fudge, I get a pudge and then I can't budge. (beat) Spike: So... no fudge? Pinkie: Aw, no thanks. I had a big breakfast.
Oddly enough, corrupted Pinkie from the first two episodes of the second season. You'd think that being brainwashed into hating anything fun would dampen this, but apparently not. Despite being angry, resentful, and dead serious, Pinkie still hops around, skates on the soap-roads (even as she protests that it's not as fun as it looks), and yells "It's your fault it didn't work!" while looking at (and meaning) nopony in particular.
Discord, the villain of those two episodes and the embodiment of Chaos, can actually make Pinkie seem somewhat sane by comparison.
If the pageant in "Hearth's Warming Eve" is to be believed (or at least taken literally), Chancellor Puddinghead of the Earth Ponies was completely off-the-wall, possibly even wackier than Pinkie! (On the other hand, Pinkie Pie was the one playing Puddinghead in the pageant, so that could be it, too.)
Chancellor Puddinghead: I was elected because I know how to think outside the box. Which means... (sticks head up a nearby chimney) I can also think inside the chimney! (beat) Can you think inside a chimney?
Vice Principal Zeigler from Pelswick is very weird and airheaded. In most episodes he does at least one nonsensical thing every other minute he has of screentime, though acting out parts of animals in the wilderness seems to be a favorite of his. There's even a Leitmotif that plays over most of his most bizarre antics.
In general, every major adult in that show falls into one of two categories: totally useless, and this trope.
Combine this trope with Affably Evil, and you have Dr. Doofenshmirtz in a nutshell.
The title brothers' father, Lawrence, though fairly grounded, is quite prone to making curious statements and not batting an eyelid at things like the TV talking back to him.
"Say, did you know they found a cure for antidisestablishmentarianism?"
Candace definitely has her moments. For instance, there's her tendency to talk into things that aren't a phone, then not be surprised when she hears a "response." The episode "Monster from the Id" shows just how quirky Candace can be.
Katie fits this trope in the episode "Bee Story", and at other points in Season 4 as well.
Pinky of Pinky and the Brain is a notorious Cloudcuckoolander, most commonly during the Are You Pondering What I'm Pondering? exchanges. One mini-episode that was done entirely from Pinky's perspective (to the point of having his snout in the camera view at all times) revealed the train of thought that led to one such exchange. It didn't come across any less weird for the explanation. Many of the Brain's schemes seem to originate from Cloudcuckooland. A giant clothes dryer?
Pretty much all of the Bortronians from Ready Jet Go!. They are all perpetually optimistic, they love making mistakes, eat odd food, talk in a eccentric English, and more. Justified, because they are aliens.
Mikey Blumberg's poems are enough evidence that his mind isn't operating on the same level as everyone elses..
Even Miss Grotke, who's Closer to Earth than the other teachers will have her moments in Cloudcuckooland.
Pops from Regular Show fits this trope perfectly. He's from somewhere called Lolliland where lollipops are currency. Not only that, in the eighties he was hit by a speeding golf cart carrying himself from the present (It's a Long Story) which seemed to have done a bit of brain damage. It's also hinted that he may have a brain tumor.
Stimpy of The Ren & Stimpy Show is an example of this. When he gets an idea, it's usually very far-fetched but due to the nature of the show sometimes it's plausible; these are evident with his theories on a simple question like, "why do kids go to school?" He responds with the answer that the kids' parents are aliens, "And while you're at school, they shed their human skins and breathe dryer lint!" When Ren hears about some of these ideas, he usually slaps him or tells him he has too big of an imagination.
In Be Cool, Scooby-Doo!, it's Daphne's turn to fill this role. She basically takes on a new quirk each episode, with varying levels of absurdity.
Captain Murphy from Sealab 2021 is like an unusually clueless child. He thinks you don't have to pay for things bought by credit card, and never quite gets what people want from him. ("If trenches are what Hollywood Actor Beck Bristow wants, then trenches he shall have!")
Homer Simpson frequently tends toward this. Perhaps most notoriously in The Simpsons Movie where he's imagining a cymbal-banging monkey... and THAT tells him to pay attention to what Marge is saying.
At one point he picks up a copy of Wired magazine, but misreads the title as "Weird", and talks about how much he loves Weird magazine and "their hilarious send-ups of hit movies." However, after reading the magazine for a bit:
Homer: Wait, this isn't Weird! (Beat) Why, there's no magazine calledWeird, is there?
Ralph Wiggum frequently strays into this trope. In fact during the show's earlier years (Pre-season 9), Ralph was a Cloudcuckoolander rather than flat out empty headed. The humor of the character came more from the awkwardness of his situation rather than pure non-sequitur until the effects of Flanderization kicked in and exaggerated his more dumber traits tremendously. Though even today, he often drops in on this trope. Some even debate every now and then whether it's right to call Ralph truly stupid, or whether he's just that detached from the world and is simply loopy.
Homer seems to get his tendencies from his dad, whose old-age senility has only exasperated it. See his Rambling Old Man Monologues for evidence, as well as the quote below.
Abraham 'Grandpa' Simpson: We had to say "dickety," 'cause the kaiser had stolen our word "twenty.
Slacker Cats: Tabitha and Dooper are both different types. Tabitha is generally insane, demanding to know why a shop doesn't sell real cat ears in her color and Dooper has insane conspiracy theories leading to one point where he shouts: "THE CHINESE EAT CATS FOR REVENGE!"
Mr. Garrison: I suppose you'll be wanting my badge and gun. (Sets a revolver on the table) School Board Member: Mr. Garrison, most teachers DO NOT CARRY A GUN! Mr. Garrison: Oh. So I can keep it then?
Confronting a student who's not paying attention in class:
Mr. Garrison: ...Well then, Stanley, what did I say? Stan: (Guessing) Uhh, you said that even though Charo appeared twelve times on The Love Boat, the episode with Captain Antonio got higher ratings. Mr. Garrison: Well, ok. I suppose you were paying attention.
Teaching a class of one:
Mr. Garrison: And so, children, that's how you tell a prostitute from a police officer. Are there any questions? Kyle: What the hell does that have to do with American history? Mr. Garrison: Good question, Kyle. Are there any other questions?
President Bush. Apparently he thinks Saddam Hussein is Satan's gay boyfriend and that he is somehow building chemical weapons plants in Heaven. Subverted in that he is completely right about everything.
He's actually portrayed as pretty intelligent in his later appearances: he's the Only Sane Man in parts of "Cartoon Wars" and almost pulls off a Xanatos Gambit in "The Mystery of the Urinal Deuce." Word of God says that they just didn't see a point in making him an idiot when every other show was already playing that joke to death.
Mel Gibson. "Ow, my nipples! They hurt when I twist them!"
A later episode shifts him into Bunny-Ears Lawyer territory, admitting that while he is dangerously insane, "...the son of a bitch knows story structure."
Parker and Stone are Cloudcuckoolanders themselves. Seriously, many of the plots to these episodes simply have to be seen to be believed.
Space Ghost in his talk show incarnation seems to fit this trope more and more throughout its run. The show turns some of its guests into this, through the writers' interview method of giving the guest a straight interview, then changing most of the questions when it comes time to have Space Ghost ask them. This method often succeeds in making the people he interviews seem a little...off.
In SpacePOP, Hera generally has... odd ideas when thinking of ways for plans to work.
Geela's robots are hilariously wrong about a ton of things, like suspecting SpacePOP sneaked into Space Port 9 by way of pouring invisible juice on themselves.
Rand the roadie is fond of non-sequiters and random humor in general.
In Spirit: Riding Free, Abigail has shades of this, such as when she concludes that teaching Lucky how to ride would turn her to banditry in "Lucky and the Treacherous Trail" or when she guesses that Respero's buried treasure might be kittens in "Lucky and the Mysterious Map."
Patrick: People used to tell me, 'Patrick, you'll never amount to anything. You'll always have your head in the clouds.' But just look at me now!note He was fried, and then restored by Neptune, but his face appeared on his butt instead of his head. Thus, his head was further away from the clouds.
Staines Down Drains: Stanley and Mary-Jane's mom can be a bit flighty sometimes. But she pales in comparison to Beef, who takes this to a whole new level.
Steven himself is an excitable young boy whose thought processes are a little weird sometimes.
Steven: I guess I'm just too tough to cry. Pearl: Just today, you were crying about snakes. Steven: (teary-eyed) They don't have any arms...
The "Pensive Moments with Steven Universe" series of online shorts showcases his odd thought processes.
Ronaldo Fryman is a Conspiracy Theorist who thinks the weird events caused around Beach City are the result of "snake people", when they're actually caused by the Crystal Gems. When Steven finally makes him realize the truth in "Keep Beach City Weird", he quickly revises his theories to revolve around a race of "polymorphic sentient rocks."
Starfire of Teen Titans frequently acts this way. It's unclear, however, what part of this is her cultural upbringing as a literal alien from another planet, and what part's her own unique personality. (The mustard-drinking incident seems to lean toward the "unfamiliarity with Earth" explanation, plus is probably a good example of Bizarre Alien Biology.) Considering her more savvy sister, it would most likely seem to be a result of her personality, plus it made for easy laughs. On the other hand, on the episode we see her homeworld, they acted more like Starfire than her sister, so the sister may actually be the odd one amongst her people.
The title character of The Tick, with his odd proverbs ("That's trouble with a capital troub!"), odder lapses of knowledge (Spanish is a "crazy moon-language") and odder Spoof Aesop a minute, as well as his battle cry of SPOON!
He came from an Insane Asylum. Says a lot, doesn't it?
TEMBWBAM: And so he says to me, you want to be a bad guy? And I say Yeah Baby! I want to be bad! I says surf's up space ponies! I'm making gravy without the lumps! Ah ha ha ha ha haaaaa!!!!!
Tiny Toon Adventures had Gogo Dodo, a literal resident of Cloudcuckooland (here called Wackyland), in which self-control is a high crime. And his father, the original Dodo, from the Porky Pig short Porky in Wackyland.
Sierra puts the 'loony' in Loony Fan! Witness her idea of a wonderland: "Let me take you to a magical place full of Codies...some are giant. Some are small enough to fit in your pocket, and others are chocolate-covered marshmallows!" Which begs the question of just WHY she would consider that last bit so nice, and whether or not she's a vore enthusiast. Her "laptop computer" is a pizza box with a live rat for a "mouse."
Izzy's defining character trait, as can be seen from her label, "The Psycho Hose Beast".
Leshawna: Is it just me, or is that Izzy girl some kind of crazy?
Owen. His thought process is very unusual, often performing spontaneous, bizarre antics like getting naked and dancing.
Blitzwing in Transformers Animated always seems to know what's going on but in his Random persona he seems to just not care, occasionally bursting into song, dancing, or going off on tangents about servo salad because for some reason he feels it's situationally relevant. The rest of him usually compensates, though, and in total he's a functioning person.
The entire show is comprised of these, as it appears everyone is dressing up as an antagonist/protagonist in order to cover for deep psychological trauma and/or lab accidents.
Hank is not only Too Dumb to Live, but he tends to lose his grip on reality easily, especially when facing the prospect of adventure. Contrast with his more down-to-Earth brother Dean, who's also rather dim but isn't nearly as crazy. Hank even acknowledges his departures from sanity when they are pointed out by others.
Brock: Honestly, Hank, where do you pick that stuff up? I never see you read.
Dean: It's weird, right?
Brock: It's like he channels dead crazy people.
Hank: (concerned) You think it's a cry for help?
Dean does have one moment (in the episode "Showdown At Cremation Creek") where he goes way off in a sort of Dune/The Lord of the Rings reverie.
Now that the show is allowing them to grow up, these tendencies are becoming less pronounced.
The Monarch, especially in the first season, the Orange County Liberation Front, the Ünterland resistance and generally about a quarter of the cast of the show.
The show's ultimate example is Doctor Venture himself, especially when he's drugged up:
Brisby: The drugs must be interacting with something in his system. The man's a pill-popper, you know.
Doctor Venture: Which one of you strapping young men is gonna catch my fall? (crashes on floor)
General Timothy Treister of the OSI. Even in the bizarre reality of this show, one wonders who put this lunatic in charge.
Almost everyone from Disney's Winnie-the-Pooh cartoons, but Tigger tops them all.
Violet from WordGirl seems to have a mild case of this. She's described by creators as one who is too lost in thought to notice on-coming traffic. She nearly gets stomped on by a giant robot because of stage-fright, and is very disoriented after giving a loud, incoherent speech on stage. However, true to the trope, often she senses problems and finds solutions faster than the title character due to her disposition.
Xavier: Yin. Yang. This world is stitched from a ballet of opposing forces. What's the opposite of day? Night! What's the opposite of black? White! What's the opposite of salt? Pepper! No, they're just two spices trying to get by. Slam! You got me! You're so smart! So—!
