Stewie: Yeah, it seemed like they were all set without you, she's done a fine job creating a child-friendly environmen-ta-re-mi-ooh, buh de buh boo, buh buh buh THPTHPTHPTHPT...
Brian slaps Stewie.Do We Have This One?? This is for a piece of dialogue that starts out seeming fairly coherent, but over time gradually deteriorates into gibberish. May be a sign of Sanity Slippage. When anger is the specific reason for this, it would be Angrish. When the gibberish precedes the character passing out, it's a Non Sequitur, Thud.
- In the Secret Six arc "Depths", one of the slaves starts to protest her treatment, to which Mr. Smythe responds by having her fellows systematically butchered in front of her. By the end of it, she's so horrified that she's begging them to stop in broken English.
- In the "Homeschooling" arc of Runaways, Klara gets so worked up after Chase keeps yelling at her that her limited grasp of English fails her and she's reduced to incoherence.
- The first line of Reality Is Fluid, with First-Person Smartass Kanril Eleya not quite listening to a politician blathering:
"This project ushers in a new era of cooperation between Cardassia and Bajor. We are healing the wounds of the Occupation and the Dominion War, blah blah blah." Okay, that last part was me.
- In Scary Movie 3, Cindy tries to warn people about the Alien Invasion, so she writes in the monitor a text for the anchorman of the news network to read and tell the audience about it. She is busted and another guy writes a correction, the two start to fight at the console and the anchorman goes from contradicting himself to speak gibberish because they write random letters.
- In Night at the Museum''s third film, when the magic tablet starts to rust, the Theodore Roosevelt replica's speech to the visitors suddenly becomes gibberish.
- H.P. Lovecraft does this "seriously" in several stories, including Rats in the Walls.
- Happens several times in Discworld:
- In Hat Full of Sky, the wizard Professor Bustle invites the eldritch creature known as the Hiver into his home, confident he can control it and make it work for him. His research notes, preserved as an awful warning to wizards contemplating following his line of research, start off as a parody of scientific notation but degenerate into megalomania of the I'll show them! type (with Multiple Exclamation Marks included), followed swiftly by babbling and then gibberish.
- Tim Benzedrine's scrawled note in Bored of the Rings''. Apparently, he took drugs before writing it and the high caught up with him in the process of writing.
- Happens a lot to Cigar in Literature/Gone. He's only coherent and himself occasionally, and sometimes he'll transform midsentence.
- In an episode of How I Met Your Mother, Marshall describes how Lily became more and more neurotic in the weeks leading up to their wedding. Cue a series of flashbacks of Lily charging into the room with increasingly irrational complaints, with the last one being a tearful "Iggy wiggy wiggy!"
Marshall: After a while, it was just... noise.
- In Blackadder III, the Prince Regent does this: "Well, that is a stroke of luck. Luck, luck, lucky laaarck lukluklukluk laaarrk, laaaaarrk!"
- This news reporter.
- In the Criminal Minds episode "Amplification", one of the last stages of the poisoning causes the victims to babble absolute nonsense. The first time it appears it's almost comical, but because this sets the audience up for this actually being dramatic, the remaining times it's shown it's Played for Drama. In Reid's case, the babbling starts mid-sentence.
- In the NewsRadio episode "Zoso", Beth tries to sell a line of hats. As the negotiations fall apart, she gets so upset that she starts blubbering incoherently, and her potential buyers decide to relent and buy her hats so that she'll stop.
- The "Stock Market Report" in Monty Python's Flying Circus:
"Trading was crisp at the start of the day, with some brisk business on the floor. Rubber hardened and string remained confident. Little bits of tin consolidated, although biscuits sank after an early gain and stools remained anonymous. Armpits rallied well after a poor start. Nipples rose dramatically during the morning but had declined by mid afternoon, while teeth clenched and buttocks remained firm. Small dark furry things increased severely on the floor, whilst rude jellies wobbled up and down and bounced against rising thighs which had spread to all parts of the country by mid afternoon. After lunch, naughty things dipped sharply, forcing giblets upwards with the nicky nacky noo. Ting tang tong rankled dithely, little tipples pooped and poppy things went pong. Gibble gabble gobble went the rickety rackety roo..."
- One bit on Reno 911! has Dangle and Wiegel dealing with a woman who's weeping so profusely that they can't get a any information out of her. Finally, Dangle starts weeping along with her and this somehow convinces her to get in the back of their squad car.
- In two episodes of Stargate SG-1 ("The Fifth Race" and "Lost City") Jack gets the knowledge of the Ancients downloaded into his brain by a computer, and his speech progressively incorporates more and more Ancient words until he can't speak English at all anymore.
"Well, apparently I have lost the falatus to speak properly." (beat) "That wasn't a joke. I didn't do that on purpose."
- In the Community, Annie tries to sing a sexy Santa song. Emphasis on tries, because her attempt at infantilization eventually goes too far, from "cute" to "creepy".
Jeff: You eventually hit a point of diminishing returns on the sexiness.
- An episode of Star Trek: Deep Space Nine had the station infected with an aphasia virus. As the disease took hold, characters rapidly became unintelligible.

- Nobody beezifies meNobody febbin ud.Kibbldzy deen voo nizee!I hate being misunderstood.
- Happens in an episode of The News Quiz, when Phil Jupitus starts to answer a question about Scottish devolution and the West Lothian Question, before realising he doesn't really know enough about the details to continue, and descending into gibberish before rallying enough to say "And I don't want the points because I don't deserve them." (Sandi then tells him it was actually a rather accurate and succinct description of the situation.)
- Former BBC presenter Sarah Kennedy lapsed into this on several occasions, a drawback in one presenting the early breakfast show on national radio. Inevitably, kindly hands had to lead her away from the microphone, ring a cab, and send her home to sleep it off (whatever the it was), while a stand-in presenter took over. Officially, it was put down to over-strong prescription medication and lack of sleep. Sarah no longer works for the BBC, or indeed in radio.
- A borderline meme example from Tales of Symphonia: Rita Mordio during Overlimit. "I'm SO gonna make you blah, blah, blah, TIDAL WAVE! Blah, blah, blah, TIDAL WAVE! Blah, blah, blah..."
- In Mass Effect, one symptom of advanced Indoctrination is increased verbal incoherence.
- The RWBY episode "Field Trip" involved the arrival of a dog so cute Weiss's speech devolved into baby talk.
- Weiss: You mean this mangy, drooling... mutt... is gonna wiv wif us foweva?
- Most egregiously:
Weiss: Oh, I'll miss you so much, we're gonna be best friends, I ka be vo q yuaouuuuu. (That last may have been her attempt to say "I can't believe how cute you are.")
- Happens a lot in Dildobitch's infamous Amnesia: The Dark Descent video.
- In I Mockery's Action Figure Aberration feature, Spider-Man takes offense to The Tick's dissing of 3 Doors Down, and starts singing their song "Kryptonite" as thus: "If I go crazy then will you still call me Superman? If I'm alive and well, will you be dere be booo bah bah! Bee blah bee!" The other action figures proceed to beat him up as he exclaims, "Kryptonite!"
- The above from Family Guy, of course.
- In the Darkwing Duck episode "The Haunting of Mr. Banana Brain", Launchpad begins stuttering uncontrollably after seeing Paddywhack's jack in the box pull in Quackerjack.
- Happens to Quick Clones in Men in Black, right before they dissolve into a puddle of goo.
- In the South Park episode "Goobacks", the "Took Your Job!" slogan spouted by the enraged blue-collar workers who've been displaced by all those people from the "feww-chure" becomes increasingly incoherent at every rally.
- Throughout the first season of Courage the Cowardly Dog, Courage actually talked throughout the episodes, spoke in complete sentences, and interacted with other characters through words. After that, Cartoon Network forced Courage to stop talking because Linda Simensky thought Courage talked too much in the first season, so Courage's dialogue was reduced to barely anything more than his frightened babbling... any actual talking he did do in those last three seasons were reduced to mostly to an Aside Comment every few episodes, or a stock recording of Courage calling out for Muriel.
- Vintage comedian and magician Tommy Cooper would do this as part of his act. He'd mumble an explanation of what trick, or sketch he was performing, and over the course of it, it would degenerate into incomprehensible gibberish. It was rather funny.
