The Rebellion Story: Homura's Soul Gem world is also one of these. It indeed appears to be cutesy Magical Girl fare, taking all sorts of cues from Lighter and Softer fanart and fanfiction depictions of the series. Then Homura discovers that the world is actually a witch barrier...
"Red-Nosed Reindeer" sounds like it would be a sweet Christmas special. It's actually a tragedy. All of Kirito's friends die in front of him because of his mistake, and then he gets a Hope Spot at reviving his girlfriend, only to find out he's six months too late. Merry Christmas.
That's not to mention the unspeakable things he did to Hogwart's in Century: 2009...
Robert Crumb was influenced by the cartoonists he read and viewed as a child, such as Carl Barks and many other Funny Animal and comedic comics and this heavily informed his personal style. The content of his work however should never be viewed by children.
The British comic Viz follows the format and style of popular kids comics from the UK, such as The Beano, but with swearing, gag penises and toilet humor.
One story is set up like a nauseatingly cute children's story, with Sam tucking Max into bed and reading him bedtime stories. Sweetly, Max asks, 'What happens when we die?'. Sam answers by cheerfully smothering Max with his pillow.
There's a whole story arc about pirates keeping manatee sex slaves (a play on the theory that the mermaid myth was inspired by sailors seeing manatees). It's played in as silly a tone as possible (complete with the pirates singing terrible love songs to them), but it's still really child-inappropriate.
In The Sandman we have it when Doctor Destiny watches TV, as he drives the world insane - one of things he watches is a kids show in which the host suddenly decides there is no hope in the world and commits suicide, while teaching children how to effectively slit your wrists. Destiny couldn't stop laughing.
The Groove Tube features "Koko the Clown", who acts like a sickeningly sweet kiddie-show host until it's "Make-Believe Time" and tells the kids to make the adults leave the room. He then sits down, lights a cigarette, and reads his viewers erotic literature, such as excerpts from Fanny Hill and de Sade's The Philosophy of the Bedroom. It adds to the effect that he selects passages his kiddie-viewers have specifically requested in letters.
Ted starts off like this, with a little boy finding that his teddy bear has come to life as a Christmas miracle to be his best friend. It's played completely straight—possibly the neighbourhood bullies are crueller than they'd usually be in a film like this—until the teddy wanders into the kitchen, and the boy's parents immediately react by asking what the fuck that thing is, and threaten to shoot it. The boy and his bear become famous all over the world... then we Time Skip to a point where the boy is now an emotionally-stunted adult, still dependent on his teddy bear, who is a Former Child Star and incredibly hedonistic and crude. After this, the subversion is complete and it drops the pretense to focus on other gags.
Uncle Shelby's ABZ Book, by Shel Silverstein, written in classic children's-book style with Silverstein's characteristic art, is designed to help let all of Uncle Shelby's little friends get what they deserve. It contains ideas for fun activities like playing hopscotch with real scotch, and explanations of amazing things like how the friendly kidnapper has nice candy and a fast car and maybe if you tell him your daddy has a lot of money he will let you ride in his car!
A Teddy Bear who comes to life to help a little girl is about as childish a cliche as you can have. Unless you've read anything by Mercedes Lackey.
There's a book that looks like a children's picture book, has artwork like a children's picture book, and is written like a children's picture book, but it's called Go the Fuck to Sleep and is aimed at adults. Made even better by having freaking Samuel L. Jackson reading the audiobook. To make up for it, there is an actual children's version of the book called Seriously,Just Go To Sleep.
The show TV Funhouse was built around this concept, featuring drinking, smoking, drug-using, psychotic puppets and parody cartoons like "X-Presidents" and "The Ambiguously Gay Duo" to great effect. It originated as a series of animated shorts on Saturday Night Live, though "Ambiguously Gay Duo" dates back even further, to the short-lived Dana Carvey Show.
Chappelle's Show had one sketch where puppets (voiced by the regulars of the show as well as Snoop Dogg) taught the kids about things like homelessness, drugs, masturbation, and STDs.
Saul Of The Mole Men, which pastiches Sid and Marty Krofft shows of the '70s such as Land of the Lost and somehow borrows heavily from/straight out parodies the short lived 70s tokuDengeki! Strada 5.
Life On Mars and Ashes to Ashes both have occasional children's programs from their time periods, altered in a way to comment on the plot. The most blatant example is their take on Camberwick Green, as seen here.
Predating most of these, Andy Kaufman often affectionately invoked and subverted kids show tropes, particularly hosts, in his work. (He actually hosted a kiddie show in Boston in the 1960s, and acts such as "Mighty Mouse" were ones he had developed and perfected as a performer at children's parties in his youth — now presented to adults.) The most famous example of this on film would be his much-delayed-from-broadcast 1977 TV special, which climaxes with an actual, sincere interview with Howdy Doody (the original puppet and voiceover performer were used), but also has such segments as "The Has-Been Corner" and reveals that his Excited Kids' Show HostHates the Job, Loves the Limelight. In his PBS Soundstage appearance, his alter ego Tony Clifton turns up as a puppet and literally kicks the butt of a Howdy Doody imposter, and a Winky Dink and You-inspired segment proves to be the key to his getting back to the show when he's banished to a desert island for "going too far". Plus, a friend recounts in the documentary The Real Andy Kaufman that Andy had broached the concept of a Christmas Special that would, among other things, have ended with a disaster involving a skydiving Santa whose parachute doesn't open...
Paul Reubens's character Pee-Wee Herman had a Subverted Kids Show done with the Groundlings that eventually becoming a real one in Pee-Wee's Playhouse. After Pee-Wee's... incident in 1991, his real kids show completed the Circle of Life and became fodder for subversion, such as the In Living Color! parody ad for a Pee-Wee Herman doll with a motorized rapid-motion arm "so Pee-Wee can beat... this drum!"
The Daily Show used to have a recurring segment called "News 4 Kids". Jon Stewart donned a cardigan, sat surrounded by stuffed toys and tiny plastic furniture and explained current affairs for the very young — in an incredibly cynical and depressing way, while smoking a cigarette and drinking from a hip flask. (They stopped making the segments in 2000 when Stewart quit smoking.)
Now they have Gitmo instead. Islamic Terrorist Elmo!
Don't forget Jon Stewart Jizz-Ams in Front of Children... uh, Jon Stewart Touches Children... oops!, Jon Stewart's Story Hole.
And that'll be... Our Little Secret.
The show also introduced a parody of School House Rock explaining the (non)importance of mid-term elections, explaining in cynical and graphic detail as to how corrupt the system really was.
One Monty Python's Flying Circus skit has Eric Idle as a kiddie TV presenter who realizes the book he's reading is pornography barely disguised as a kiddie storybook.
Eric: Hello, children, hello. Here is this morning's story. Are you ready? Then we'll begin. (opens book, reads) 'One day Ricky the magic Pixie went to visit Daisy Bumble in her tumbledown cottage. He found her in the bedroom. Roughly he gabbed her heavy shoulders pulling her down on to the bed and ripping off her...
From Flight of the Conchords: "In the marmelade forest, between the make-believe trees, in a cottage cheese cottage, lives Albi... (Albi)... Albi... (Albi)... Albi the Racist Dragon!"
One of those Top 50 Somethings shows on British TV had Sweep shouting "F**K OFF!" at the presenter. Now I know you can say it's just a beeping note but anyone who grew up with those characters always knows what it means.
On a similar but genuine note, the performers doing the slide whistle noises that formed the speech of The Clangers had actual words in mind, and if you know what they are you can actually recognise it. As shown on QI, one particular line was "Oh, sod it! The bloody thing's stuck again."
Look Around You. Look around you. Just look around you. Have you worked out what we're looking for?
A recurring sketch on Rowan and Martin's Laugh-In features a kid's show hosted by Uncle Al, the Kiddies' Pal. "Uncle Al had a lot of medicine last night!" was the hungover host's usual catchphrase.
Saturday Night Live has a lot of sketches that are about screwed-up kids' shows or have premises that would make it a screwed-up kids show if it were played during the hours when kids may be watching.
From the 1970s, there was Mr. Bill, a little clay guy who was constantly squashed, sliced, and otherwise tormented, often by the aggressive Mr. Sluggo. He got no help from his supposed friend Mr. Hands either. "Oh nooooooooo!" Later incarnations of Mr. Bill were actually pitched at kids as well as adults, without having to change things!
In the 1990s, there was "Jingleheimer Junction", a show with Umberto Unity (Horatio Sanz), Katie Kindness (episode host Cameron Diaz), and Clara Caring (Ana Gasteyer), all of whom wore sweaters with the letters of their first names. Guess what happened when Freddy Friendship (Will Ferrell) joined the cast.
The Season 24 episode hosted by John Goodman had "The Happy Smile Patrol," which combined this with the "Funny Aneurysm" Moment (another trope SNL is familiar with) with repeated news reports of the actors and actresses from the show involved in violent, horrific acts interrupting the broadcast.
News anchor: Once again: Teddy Tickles, Glenda Giggles, and Harry Hugs have now taken their own lives, after a killing spree that claimed, among others, Cuddly Kevy. A tragic, tragic day. We now return to "The Happy Smile Patrol".
The 2000s brought us a one-off sketch on the Season 28 (2002-2003 season) episode hosted by Ray Liotta where one of the cast members of a Barney The Dinosaur-esque TV show has grown boobs during her hiatus and the director (and the actor in the Barney-esque costume) trying to do the show despite the actress's Gainaxing and the ensuing Accidental Innuendo.
Season 33 had, in the Seth Rogen-hosted episode, a parody of The Muppet Movie in which their bus hits and kills a guy. When a cop (Kenan Thompson playing 1970s comic Nipsey Russell) pulls them over to question them, Zoot shoots him!
The second time James Franco hosted (during 2009-2010's Season 35) had an SNL Digital Short featuring Franco as the special guest star on a children's show called The Tizzle Wizzle Show where the kid actors dance around in pajamas. It turns sinister when the knives and pills are handed out and the show ends with James Franco as the sole survivor of a dangerous murder-suicide game.
Not to be left out, MADtv had The Reading Caboose, which mingled the tropes from children's shows with subjects from the Conspiracy Theory tropes page.
Primetime Glick featured a segment called "Tales from Lalawood," which featured Jiminy Glick telling children gruesome tales of celebrity murders, suicides, etc., told for the children with cute marionette puppets.
The Angel episode "Smile Time" involved a children's TV show being used by evil demonic puppets to suck out the life force of the children watching the show. While investigating, Angel ends up being turned into a puppet himself. And can still kick Spike's butt (although admittedly Spike was a bit too busy laughing his ass off to put up much of a fight...)!
Biffovision, an aborted BBC series by the co-creator of Teletext's surreal gaming magazine, Digitiser, sees the traditional Saturday-morning magazine show given a surreal and overtly adult twist.
The Game ShowFunHouse was an actual kids' show. Its Spin-OffCollege Mad House... not so much. They basically replaced the kids with college students, made the stunts risque, and changed the names of the obstacles in the house to things like "Roommate from Hell".
German late night Harald Schmidt Show had a recurring segment featuring sock puppets Bimmel und Bommel explain each letter of the alphabet by citing deadly diseases and mass-murdering dictators beginning with said letter, along with crude sexual references.
Brian Conley did a famous (in the UK) series of sketches poking fun at the tropes of kids' TV presenters, "Nick Frisbee and Larry the Loafer", which feature both age-inappropriate material and the audience going 'ooh' when Larry (a squirrel puppet) is beaten by Nick, to which he responds "IT'S A PUPPET!!"
In Living Color! went to this well more than once. The Candy Cane Show had a female presenter who couldn't hide her neuroses (about relationships, aging, etc.) behind her perkiness, and The Scary Larry Show was hosted by an unstable Vietnam veteran/postman who had a similarly shell-shocked buddy as a sidekick.
Ru Pauls Drag Race often includes putting one of these on as part of the competition of its Drag Queen competitors, with the aim to of course cram as much innuendo as possible into the sketches.
SCTV had "Mrs. Falbo's Tiny Town," a parody of children's television where Andrea Martin plays a naive kids TV show host with John Candy has her dumb jester clad sidekick who do insane things that almost get them killed like visiting a populated maximum security prison. In the final, Cinemax-produced season, alcoholic Happy Marsden hosts a children's show called "Happy Hour" live from a local tavern.
The rationale behind casting Tom Baker as the narrator in Little Britain. With his distinctive voice being fundamentally linked to the childhood of a large chunk of the audience, he spends his role babbling in a similar tempo and vocabulary to that used by the Doctor he played. Of course, what he's saying is invariably obscene, bigoted, sexually depraved or any combination of the above.
An in-universe example in "The Waldo Moment" - Waldo is a character from a segment on a late-night satirical show where a cartoon bear interviews various celebrities in a set designed to look like one from a children's show, where he uses a lot of foul language and crude humour. There is a certain amount of subtle Stylistic Suck applied.
Lily Allen's "Alfie" is set in a brightly-coloured house that looks like the set of a children's show, but is offset by a rude little hand puppet smoking joints and generally being horrible.
And masturbating. Don't forget masturbating.
The video for Will Young's "Who Am I?" digitally inserts him into a number of old children's shows, including Blue Peter.
Kate Nash's "Pumpkin Soup" is set in a children's TV set, with certain homages to Bewitched visible...
The set for the music video of Hard 'n Phirm's "Pi" is "Zap", which apes the TV show "Zoom".
The video for Lostprophets' "A Town Called Hypocrisy" features the band as characters in a parody of kids shows such as Playdays or Playbus called "Town Time", intercut with a debauched cast party.
Dizzee Rascal's "Dream" is a spoof of British children's shows in the 50's, with a miniature Dizzee interacting with puppets atop a piano, presided over by a grandmotherly looking woman.
Rather than a kid's show, Muse's "Invincible" featured the band on an amusement park ride obviously modeled after the It's a Small World ride. The ride shows a very abbreviated history of man, with an unsettling focus on wars; after the September 11 recreation, everything goes completely insane.
Serj Tankian's 'Empty Walls' video takes place at a day care (where he seems to perform) rather than an actual show. And then the little kiddies start acting out America's 'War on Terror' on each other..
Primus's video for "Wynona's Big Brown Beaver" has them in kids-show appropriate cowboy costumes and animations of Winona with a pet beaver to lyrics like "Wynona loved her big brown beaver and she stroked it all the time." It was so well-executed that not even the kids caught on.
While Kunt and the Gang never fit the Depraved Kids' Show Host archetype, much of his music fits into this trope; examples include "Fucksticks," "Gentleman's Wash," "I Was Pissed Out Of My Head" and "Wank Fantasy," which sounds like The Wiggles' evil twins broke into their recording studio.
Later double-subverted: as part of a campaign to get "Fucksticks" played at the Royal Wedding, he issued a family-friendly version aimed at small children.
Miley Cyrus's performance at the 2013 VMAs used a lot of this as part of her Former Child Star persona. For instance, she showed up with her hair in two little childish topknots, and was wearing a teddy bear leotard - the teddy's face had bloodshot, unfocused eyes and was sticking its tongue out lasciviously. She also had teddy bear-costumed backup dancers, portrayed by twerking black women with big butts, while singing a song about partying on molly and coke. And that's just the start. In short, despite being a star marketed towards children for most of her career, her performance in that show absolutely should not be viewed by children. Or anyone else.
Peter Jackson's Meet the Feebles is a Muppets-style musical comedy in which puppets have sex, do drugs, and commit mass murder with a machine gun.
Wonder Showzen parodies Sesame Street and the like. Sketches have included a George W. Bush-inspired "Middle America" muppet castrating the cast, a sexual affair between the letter P muppet and a pile-of-feces muppet, "interview" segments in which actual children "report" on various things out in the big wide world — and ask the folks there questions about their sex lives, and an entire episode parodying Hee Haw, packed full of offhand jokes glorifying domestic violence, inbreeding, and situational homosexuality.
What makes Wonder Showzen even more on the nose in terms of this trope is the fact that its original title actually was Kids Show.
Greg the Bunny is the result of someone asking "if puppets did live amongst us, what would it be like?" It follows the daily exploits of the writers and actors on a kid's show, but demonstrates how the puppets aren't kid-friendly behind the scenes. There's swearing, "anti-puppetism", drinking, and lots of sex.
The show's second pilot on IFC included strong implications that one of the cast members was a rapist.
The Sifl and Olly Show is a borderline example. While it does have sock puppets, songs and "educational" skits it was generally less interested in corrupting something pure than it was having fun with it's own unique brand of weirdness.
The Avenue Q Broadway stage musical (origin of the infamous song "The Internet Is for Porn", among others), is a blatant parody of Sesame Street... with swearing, drinking, smoking, and sex. The writers have described it as "if Sesame Street taught adults how to live". Believe it or not, the show actually won three Tony awards: Best Score (Music & Lyrics), Best Book, and Best Musical.
Also, many cast and crew members were, at one point, in Muppet productions.
Also setting the show apart (and key to its success and acclaim) is that it doesn't run on pure cynicism or subversion. You actually care about the characters, and its ultimate life lessons (as found in "The Money Song" and "For Now") are actually uplifting pieces of advice.
This show just might be a subversion of a subversion... one of the creators said something to the effect of "What we're doing, we're not subverting Sesame Street at all. Sesame Streetitself is a subversive show."
Brian Henson's Stuffed and Unstrung is an attempt to do this by the Jim Henson studio.
The German Freitag Nacht News did Bernie und Ert (later Bullzeye), which took the Ho Yay in Ernie and Bert and cranked it Up to Eleven. With darkrooms and gimps suits.
Mongrels, a BBC Three show about a bunch of urban puppet animals; swearing, sex, inbreeding and all sorts of unsavoury shenanigans.
Hale And Pace did a sketch of this once. Among the attractions were a counting game where they "took away" friends with a handgun, not to mention the letters of the day were... P! M! and T!
Tomorrow's Pioneers, a Palestinian show (specifically made by the radical Hamas group) where they indoctrinate kids to hate Israelis and become Suicide Bombers. Here, for example, is a video in which a Mickey Mouse clone named Farfour cheats on a school test, then blames it on Jews. Later, due to Disney threatening legal action, Farfour was killed by a member of Mossad (Israel's even-nastier version of the CIA), whom he calls a terrorist. Farfour was replaced by a bee named Nahool, who taught children not to abuse animals... by hitting cats and picking them up by their tails, and throwing stones at lions. Later, Nahool died of a disease when Israeli authorities refused to allow him passage to Jordan for surgery, and his replacement Assoud (a guy in a Bugs Bunny suit) was killed by Israeli bombing. The next presenters, Nassur and Sarara, managed to survive until the end of the program's run.
The Israeli version of Sesame Street, Rechov Sum Sum is generally much milder in comparison, though it has featured Muppets as members of the Israeli Defense Force, and they make no bones about how they are packing mad heat.
George Carlin and Jack Burns did a skit called "Captain Jack and Jolly George", or what it would look like if a pair of beatnik hippies got their own kids' show. Needless to say, it's not really for children. And then George Carlin went and played "Mr. Conductor" on the American version of Shining Time Station. He then went on to do a stand-up routine on parenting (entitled "Fuck the Children") in which he tells parents "And remember, this is Mr. Conductor talking; I know what I'm talking about."
Robin Williams plays a Mr. Rogers-esque kiddie show host in a segment of one of his early stand-up specials. He puts a hamster in a microwave ("Pop goes the weasel!") to demonstrate to kids how "we're all going to die from radiation", much to the disgust of the show's director.
Dog Sees God is this trope applied to Peanuts. Somehow, teenaged Charlie Brown manages to suffer even more than he did as a kid.
Avenue Q features mostly puppeteers and voice actors from Sesame Street. Some of the characters even have Muppet voices, such as Nicky having the voice of Kermit the Frog (or more likely Ernie, given Nicky is clearly an expy of him; they sound similar because both characters were originally voiced by Jim Henson). Who would've suspected that it has full male puppet nudity?
Brian Henson's Stuffed and Unstrung is an attempt to do this by Jim Henson studio.
Conkers Bad Fur Day. The game's original concept, Twelve Tales, would have been more appropriate to general audiences; however, after the gaming press accused Conker of being yet another cutesy Rare platformer in the vein of Banjo-Kazooie, Rare decided to completely rewrite the scenario to include more sex, violence, swearing and Toilet Humor. What it would have been can be seen in the GBC game Conker's Pocket Tales. In fact, the only thing that seems anything like the original Twelve Tales concept that's left in the game was the fire-farting dragon, which really isn't any worse than some of the jokes snuck past the radar in Donkey Kong 64 and Banjo Kazooie.
Eversion starts out as happy, colorful, smiley all around, and quickly begins turning into a big old pile of Nightmare Fuel with pools of blood, black clouds of death slowly engulfing the world, and those demon hands that start popping up out of nowhere!
The Reality Warper Peacock from Skullgirls lives this kind of life; thanks to cartoons negatively influencing her already tortured and unstable mind, she became a foul-mouthed, chain-smoking, highly dangerous thug who travels with an equally dangerous ensemble of living objects including an anvil and two bombs, and most of her attacks involve cartoony physics and gags that have a very realistic degree of killing power.
The character of Monokuma in Dangan Ronpa, a horrible, but hilarious scheming murderer, played in the Japanese version by the voice actress for Doraemon. The famous Let's Play of the game notes that Doraemon's voice virtually is childhood in Japan, and Japanese players invariably have a huge reaction as soon as Monokuma starts speaking.
One Order of the Stick features the Empire of Blood's grim version of an overcommercialized and over-hyped parade, including dark parodies of Sesame Street characters (Little Roc, Hurt & Burnie, etc). Inverted with Felix the Mensch, a benign counterpart to Oscar the Grouch.
Hell Homestuck itself sort of counts. It's got a bright and cartoony art style and the basic premise sounds like something out of a Saturday morning cartoon (some kids play a video game that turns out to be able to change the world) so it initially looks like a kid's comic. Than you reach the first f-bomb...
In Jen Babcock's C'est la Vie, dogsbody character Louis Lamoureux gets his big break into television - inside the Reading Rabbit costume, which, as the name implies, means he has to turn kids on to the magic of books by reading stories to them. But some of the kids have other ideas...
Similarly, in the very first couple of episodes of the comic, anti-heroine Mona Montrois establishes her character as a cynical snarker by getting sacked from a nursery teacher job. She tells the kids the fairy-tales as they originally were, short of froth, glamour and happy endings...
This is a major theme in Youtube Poop. While kids' shows aren't the only thing used in YTP, they are one of the main things in it, and the comedic effect of editing things to sound vulgar is a lot more noticeable when the source material itself is for children. This is taken Up to Eleven by YTPs of Edu Tainment shows like "Dr. Rabbit's World Tour."
Happy Tree Friends, which is actually incredibly violent. The official websites had labels reading "CARTOON VIOLENCE" and "not appropriate for children under 12" all over it back when it still had its own website, but there were still parents complaining about their six-year-olds stumbling upon it.
Retarded Animal Babies, which crosses the line twice as much with Gorn and porn. Sometimes, but not always, funnier.
An inversion, taking the very serious Watchmen and turning it into an 80s saturday morning cartoon. Beware.
And the animation studio's slogan? "Touching your inner child"....
Doctor Steel's webisodes of The Dr. Steel Show are done in the style of kids shows but are quite subverted. Also his song, Smokey's Theme, ostensibly the theme song for a kid's show about a cigar-smoking trout who loves children.
"Lost Episode" and "The Truth Behind [show]" creepypastas do the same thing, describing an episode with horrific Deranged Animation and putting forward theories that the characters are based off dead people respectively.
LoadingReadyRun has a recurring gag where a Mr Roger's-like host is seen reading the end of a children's book and then giving a moral to the story such as "never go outside".
The webcomic Clarissa is about a little girl living with her happy, seemingly perfect, family. It appears to be nothing that you wouldn't see in a newspaper or on a kids network. It just happens that everyone is a Stepford Smiler and that her father rapes her at night. It's played for laughs. The darkest laughs ever.
Doobl at first looks like a fairly standard Christian webcomic (with lame yet frequent bible jokes), but when a Death by Newbery Medal storyline comes up, Neek tells Doobl that animals don't have souls. After reading the bible to verify, Doobl begins to degenerate in both faith and family-friendlyness. Soon, Doobl becomes a jerkass and starts spewing profanity. Humi, up until this point an exception to Reptiles Are Abhorrent, studies the bible in an attempt to save Doobl, only to become just like him. It goes From Bad to Worse the moment Humi discovers his penis...
Don't Hug me I'm Scared by This Is It starts off like a kid show, with a talking notepad singing to some puppets about being creative. It goes downhill from there and ends with the puppets doing art projects with and cutting up a cake made from human organs, and painting the word "DEATH". The last line of the song, appropriately enough, is "Now let's all agree to never be creative again". The second video has the puppets learning about time, before learning that eventually, everyone runs out of it as they slowly rot alive.
The SCP Foundation plays host to SCP-993, a cartoon show called "Bobble the Clown" broadcast by an unknown station. Anyone over the age of ten suffers a splitting headache and falls unconscious when trying to watch the show; anyone under the age of ten is subject to watching Bobble teaching them how to do horrible things, like kidnap an ordinary suburbanite and cook his flesh, stalk and murder a London woman, or torture a prisoner of war. Alarmingly enough, Bobble is aware that the SCP Foundation is trying to keep his show from being broadcast, and has produced an episode showing kids how to release several of the Foundation's more dangerous specimens and murder the researchers keeping him contained.
The "Counting Song" by Adam Buxton begins like a song teaching numbers to young children and suddenly turns in an increasingly desperate rant against the life as an adult.
Done a few times on Homestar Runner. The Strong Bad Emailkids' book has Strong Bad "write a children's book." Which means he steals a book called "Everyone Is Different" from his brother and turns things like "Some people are very tall. Quincy is very tall." into "Some people are very tall and merciless. Quincy is destroying San Antonio" with a black Sharpie.
Another Strong Bad Email suggests that Strong Bad get his own children's show. He then explains why he's not 'cut out for that kind of sugarjob.'
The show Robot Chicken breathes and lives in this trope. It would take at least half a page to list children's shows that it "corrupted".
Here's a good drinking game, go onto YouTube, watch a whole bunch of Robot Chicken sketches, and take a shot every time one of the top-voted comments is some sort of remark about a "ruined childhood". [adult swim] has even made a playlist for those that want to speed up the process.
Krusty: Hey Hey, kids! Watch my show and I'll send you this book featuring me in a variety of sexually explicit positions. (Krusty is being dragged off by executives) Krusty: What? Hey! It's not really me; I used a stunt butt!
Bart even has the Krusty the Klown Home Pregnancy Test.note Warning - May cause birth defects
On the episode premiering December 15, 2013, Krusty mentions that he's always drunk or high when The Itchy and Scratchy Show is on. When he finally watches an episode sober, he's horrified and kills the feed.
Family Guy will do this in their "cutaway gags", sometimes featuring kids shows and other material often associated with juvenile audiences. One example would be when Elmer Fudd not only successfully shooting Bugs Bunny (to bloody effect), but watching as the hare writhes in agony before snapping his neck.
The pilot episode of the Black Dynamite animated series features a thinly-veiled parody of Sesame Street that had fallen into crime and disrepair, with the Kermit the Frog equivalent manipulating children to give him money.
The Beetlejuice episode "Uncle B.J.'s Roadhouse" was a parody of Pee-wee's Playhouse.
The Powerpuff Girls had the episode "Neighbor Hood", about a children's TV show host who entreats his young viewers to send the show "happy paper" from their parents' wallets to keep the show's stars alive and happy (a nod to what Soupy Sales pulled in the early 60s on his kids' show). This season 5 episode was originally planned for the first season but the staff feared a lawsuit from Fred Rogers (Mister Rogers' Neighborhood) as it paralleled his show a bit too closely. It was given to DC Comics as issue #7, "Remote Controlled," and then refurbished as this episode.
Trip Tank is a animated Sketch Comedy show that loves pulling this with some sketches starting out rather harmless and cutesy and then someone gets slighted and...let's just say retribution ends in blood and death the majority of the time.
Rick and Morty does this in "Rixty Minutes", where interdimensional TV shows include a Lucky Charms commercial featuring zombie-like children gruesomely disemboweling Lucky, and a somewhat cruder version of Garfield.
On a Spring 1994 episode of the French series Jacky Show, singer/actress Mallaury Nataf performed her song "Fleur Savage" while wearing a short dress and no panties, and ended up flashing both sides, triggering a scandal.
