Two tropers tarried to talk "tongue-twister" topic's techniques. Tropers' tongues twisted till tropers' tangled tongues tied totally taut. Talking troubles taught tropers twain to tackle tortuous tongue-twisters tentatively.

In plain language, a tongue twister is a sentence or phrase that's meant to be difficult to say, generally because it incorporates rhymes, near-rhymes, alliteration or all three. The simultaneous excitation of so many closely-linked neurons in the brain's speech centers results in unintended {{Spoonerism}}s and VerbalTic-like errors, mid-phrase. Sometimes these phrases are constructed so that the errors will generate [[InnocentSwearing unintentional]] swear-words. A tongue-twister is generally easier to say when speaking slowly; often, short ones will be accompanied by a challenge to say them [[RuleOfThree three times fast]].

These sayings occur both as works in themselves, and as features of larger works. Often, when a tongue twister is employed within a broader work, it's as a comedic element focusing on just how hard it is to say the phrase properly. Both in RealLife and in fiction, they can be used to practice enunciation in speech therapy and oratory training.

Interestingly, an equivalent concept exists in sign languages, in which difficult-to-sign phrases are known as "finger fumblers".

A sister trope of CannotSpitItOut. If applied to a name, it'll become TheUnpronounceable.

!!Typical tongue twisters:

* William Poundstone declared this to be the most challenging tongue-twister in the English language:
--> The seething sea ceaseth and thus the seething sea sufficeth us.
* This old song, the first line of which is a well-known example:
--> She sells sea shells on the sea-shore,
--> The shells she sells are sea-shells, I'm sure.
--> For if she sells sea-shells on the sea-shore
--> Then I'm sure she sells sea-shore shells.
* Just ''try'' to rattle off the following without an error:
--> Betty Botter bought a bit of butter.
--> The butter Betty Botter bought was a bit bitter
--> And made her batter bitter.
--> But a bit of better butter makes better batter.
--> So Betty Botter bought a bit of better butter
--> Making Betty Botter's bitter batter better.
* This submission won a contest in ''Games'' magazine in 1979:
--> Shep Schwab shopped at Scott's Schnapps shop;
--> One shot of Scott's Schnapps stopped Schwab's watch.
* This one, while less difficult, is still plenty impressive to rattle off at speed:
--> Around the rough and rugged rock, the ragged rascal randomly ran.
* Some high-speed examples, which become tongue twisters if said quickly and repeatedly:
** A Proper Copper Coffee Pot.
*** This one inspired a tongue-tangling song by the folk band Trout Fishing In America.
** Betty Bopper's battering batton made Bertie Bopper bite her.
** Cecily thought Sicily less thistly than Thessaly.
** Irish wristwatch.
** Peggy Babcock.
** The bog above Bob Gorman's bog.
** Pleasant mother pheasant plucker.
** Red Leather, Yellow Leather.
*** (Alternately): Red Lorry, Yellow Lorry.
** Rubber Baby Buggy Bumper.
** Smiley shlug with Shloer.
** Mad Man.
** Unique New York.
** City Shellfish.
** Toy boat.
* Some other classics:
->Peter Piper picked a peck of pickled peppers --
->A peck of pickled peppers Peter Piper picked.
->If Peter Piper picked a peck of pickled peppers,
->Then where's the peck of pickled peppers Peter Piper picked?

->How much wood would a woodchuck chuck
->If a woodchuck would chuck wood?
** And its answer:
-->All of the wood that a woodchuck ''would'',
-->''if'' a woodchuck ''could'' chuck wood!
** Or the variant:
->How much whey would a zimbab weigh
->If a zimbab would weigh whey
* According to at least one edition of the ''Guiness Book of World Records'', the world's hardest tongue twister (or at least in English) is:
-->The sixth sick sheik's sixth sheep's sick.
* "Fuzzy Duck" and "Duckie Fuzz" will eventually make the speaker mess up and say "fuck".
** The woodchuck example above is also intended to do this, as is the "pheasant plucker" variant.
* A German one that translates quite well:
->''Fischers Fritze fischt frische Fische, frische Fische fischt Fischers Fritze.''
--> becomes in English:
->Fisher(man) Fritz fished fresh fish, fresh fish fished fisher(man) Fritz
* Announcers' tests, used to determine if someone has a suitable speaking voice for radio or narration, often include tongue-twisters. A classic example requires reciting the following, from memory, without an error:
--> One hen
--> Two [[{{Duck}} ducks]]
--> Three [[NoisyNature squawking geese]]
--> Four [[UsefulNotes/{{Ireland}} Limerick]] oysters
--> Five [[DolphinsDolphinsEverywhere corpulent porpoises]]
--> Six bottles of smooth and pink [[ProductPlacement Pepto Bismal]] (or Six pairs of Don Alverzo's Tweezers)
--> Seven thousand [[ProudWarriorRace Macedonians in full battle array]]
--> Eight [[EverythingsBetterWithMonkeys brass monkeys]] from the [[AncientTomb ancient, sacred crypts]] [[AncientEgypt of Egypt]]
--> Nine [[GrumpyOldMan apathetic, sympathetic, diabetic old men]] [[CoolOldGuy on roller skates]] with a [[LazyBum marked propensity towards procrastination and sloth]]
--> [[SerialEscalation Ten lyrical, spherical, diabolical denizens of the deep who haul stall around the corner of the quo of the quay of the quivery, all at the same time]]

There are a few tongue twisters that seek to take advantage of you. These are {{NSFW}} when said aloud and messed up.

-->I'm not the pheasant plucker / I'm the pheasant plucker's son
-->I'm only plucking pheasants 'til the pheasant plucker comes.

-->Silent Susan sits in her Chevrolet.
-->She sits and she shifts and she shifts and she sits.

!!Tongue-tangling in tales:

* DrSeuss' ''Fox In Socks'' is made up of examples of this trope, as well as ''Oh Say Can You Say''. ''Fox in Socks'' is a more solid tongue-twisting read.
** ''Oh Say Can You Say'''s twisters are of varying quality and ease, but a few of them top ''Fox in Socks'' individually. We're looking at you, "Never buy your Daddy a Walrus".
-->A walrus with whiskers is not a good pet.\\
And a walrus which whispers is worse even yet.\\
When a walrus lisps whispers through tough rough wet whiskers,\\
your poor daddy’s ear will get blispers and bliskers.
* Practically everything that comes out of V's mouth in ''ComicBook/VForVendetta'' qualifies. One wonders how many takes it must've taken to produce his dialogue for [[Film/VForVendetta the film]]...
* Non-alliterative example: In ''[[Creator/StephenKing It]]'', Stuttering Bill's speech therapist has him recite "He thrusts his fists against the posts and still insists he sees the ghosts". This awkward sentence becomes something of a confidence-building mantra for Bill.
* Actors often use these to warm up for a performance; if someone is about to go onstage (in-universe or otherwise), you might see them preparing by speaking one of these aloud.
* In ''TheBradyBunch'', little Cindy was attempting to get rid of her lisp:
-->'''Cindy:''' She sells seashells by the seashore. She sells seashells by the seashore. She sells seashells by the seashore.
-->'''Marcia:''' Cindy, would you mind practicing somewhere else? Arithmetic is kind of hard.
-->'''Cindy:''' So are S's.
* ''WesternAnimation/FamilyGuy'' had a ManateeGag mocking ''TvsBloopersAndPracticalJokes'', with a blooper from ''Joanie Loves Chachi", with Chachi attempting to say "She sells seashells by the seashore", [[spoiler:he gets attacked by a bear]].
* 2d!Doofenshmirtz in ''WesternAnimation/PhineasAndFerb Across The Second Dimension'':
-->''2D!Doof:'' Boy borg. Try saying that five times fast. Boyborg, Boyborg, Boyborg, Boyborg, Boyborg...I guess maybe [[SubvertedTrope it's not that hard to say]].
* These are used as teaching tools in ''MyFairLady'': "In Hertford, Hereford and Hampshire, hurricanes hardly ever happen."
** At the Ascott race, Eliza shows off her eloquence by discussing the weather in tongue twisters.
* A variant of the "announcers' test" example, above, appears in the 1997 novel ''Matters of Chance'' by Jeannette Haien:
--> One good hen
--> Two ducks
--> Three cackling geese
--> Four plump partridges
--> Five Limerick oysters
--> Six pairs of Don Alphonso tweezers
--> Seven hundred Macedonian horseman [''sic''] dressed in full battle array
--> Eight sympathetic, apathetic, diabetic old men on crutches
--> Nine brass monkeys from the Sacred Sepulchres of Ancient Egypt
--> Ten lyrical, spherical heliotropes from the Iliad Missionary Institute
* ''The Pheasant Plucking Song''
** Fred Colon, of the Literature/{{Discworld}} City Watch novels, was once in a military regiment called the Pheasant Pluckers. In reminiscing, he recalls how the regimental song was a bit difficult to sing correctly.
* Edward "Eddy J" Lemberger's ''[[ExactlyWhatItSaysOnTheTin The Tongue Twister Song]][[ExcitedShowTitle !]]''
* In episode 14 of ''LightNovel/{{Bakemonogatari}}'', Koyomi Araragi deals with [[CatGirl Black Hanekawa]] ([[spoiler:Tsubasa Hanekawa possessed by a ''male'' bakeneko she refers to as a "meddlesome cat"]]), whose appearance, demeanor, and actions get a rise out of [[ChivalrousPervert Araragi]]. He then asks her to repeat, "Can you imagine an imaginary menagerie manager imagining managing an imaginary menagerie?" Not only does she repeat the tongue twister flawlessly, but she finds the time to throw in her cat-based VerbalTic as well. [[CutenessProximity Araragi is quite impressed.]]
-->'''Black Hanekawa:''' "Can mew imyagine an imyaginyary mewnyagerie mewnyager imyagining mewnyaging an imyaginyary mewnyagerie?"
* On ''Series/ThirtyRock'', Jenna starred in a film called "The Rural Juror", which no one can pronounce without it sounding like gibberish.
* In one of Creator/JasperFforde's ''Literature/ThursdayNext'' books, a fictional character gets Thursday to try to say one, and is quite intrigued by her inability, because fictional characters have no trouble with them.
* There are numerous tongue twisters in the ''WesternAnimation/PinkyAndTheBrain'' episode "You Said a Mouseful", wherein Brain attempts to put helium into hacky-sack sack-kicker shoes in a Hackensack factory.
-->'''Brain:''' You must slit the sixth sick sheet slitter's son's sheet, secure it next to the toy boat from the Hackensack Socko Kicky-Sack Sack Kickers' picnic in Secaucus, stretch it past the sack pickers' station and the sock plucker's chute, and pick a sack, pluck a sock, and flick the plug, so I can put the pea in the plucked sock with the picked sack for ballast and bounce it off the rubber baby buggy bumper, into the Parker Packard purple pewter pressure pump.
* In one of the Harlem Globetrotters episodes of ''WesternAnimation/TheNewScoobyDooMovies'', the normally ComicallySerious Velma challenges her friends to say, "Something's thumping," three times fast. Shaggy doesn't even want to say it once.
* ''The Last Crown'' (sequel to ''VideoGame/TheLostCrown: A Ghosthunting Adventure'') includes the phrase "powerful paranormal phenomena", which the creator's blog suggests gave voice actress Emma Harry some RealLife Tongue Twister issues.
* In an episode of ''Series/TheColbertReport'', MartinFreeman discussed playing Bilbo Baggins in ''Film/TheHobbit''. He mentioned how thrilled he was that he, along with the rest of the cast, were immortalized as Lego figures.
-->'''Colbert''': Is there a Lego Legolas?
-->'''Freeman''': Yes, but he only goes down to here (indicates his waist) so he's a legless Lego Legolas.
* This exchange in ''AFunnyThingHappenedOnTheWayToTheForum'':
-->'''Miles Gloriosus''': Oh, her bridal bower becomes a burial bier of bitter bereavement!
-->'''Pseudolus''': Very good! Can you say "Titus the tailor told ten tall tales to Titania the titmouse"?
* In ''Discworld/FeetOfClay'', Vimes recites "Peter Piper picked a peck of pickled peppers" to prove he's not drunk.
** Conversely, in Heinlein's short time-paradox story "By His Bootstraps", Wilson demonstrates that he '''is''' drunk by reciting the same phrase, and having it come out "Peter Piper pepped a pick of pippered peckles".
** In ''[[GarrettPI Wicked Bronze Ambition]]'', Garrett's sorceress companion teases him about [[DoesNotLikeSpam his least favorite food]], saying that if he could ban green peppers as he wished, his criminal friends would all start picking and packing pecks of peppers for the black market.
* ''Film/TheJerk'' has a scene of Navin TalkingInBed with Marie:
-->'''Navin''': Marie, are you awake? Good. You look so beautiful and peaceful, you almost look dead. I'm glad because there is something that has always been very difficult for me to say. "I slit the sheet, the sheet I slit, and on the slitted sheet I sit." I've never been relaxed enough around anyone to be able to say that.
* A regular feature on ''Bosco''. Two animated characters would say the Tongue Twister more and more quickly as their necks expanded. [[WhatDoYouMeanItWasntMadeOnDrugs It was that kind of show.]]
* In a Toyota commercial, a saleswoman sums up a family's car-buying preferences:
--> "So, Clarence is here for clearance to get Cammy a Camry, and Blake wants it in black."
* In the "Martha's Got Talent" episode of ''WesternAnimation/MarthaSpeaks'', the talking dog plans to demonstrate her ability to recite tongue twisters in a talent contest [[spoiler: that's really a set-up by some bumbling would-be dog-nappers]].
* The "Three Musketeers" sketch from ''Franchise/TheMuppets Go to the Movies'' involves the Scarlet Pimpernel dropping a crumpet made from pumpernickel, covered in lumps, from Humperdink's bakery, [[OverlyPrepreparedGag leading to the line]] "It's that simple wimp, Pimpernel, and his Humperdink's lumpy pumpernickel crumpets!" Link Hogthrob, playing one of the Musketeers, keeps stumbling over the line.
