->''"Does any kid still do this anymore?''
->'' Does any kid still do this anymore?''
->'' Does any kid still do this anymore?"''
-->-- '''WesternAnimation/TheSimpsons''', "Bonfire of the Manatees"

A character is given a line to write over and over and over again as punishment. In the classic version, the character is a child in school, and the line is of the form "I will/must not (do X) in class."

Coming up with methods to evade, enliven or simplify this punishment is commonly attempted. These include getting a computer program or magical spell (in WizardingSchool) to write the lines automatically, taping multiple pens together so you can write multiple lines at a time (which does ''not'' work in RealLife), drawing a vertical line down the page to reduce each sentence by one word (by creating a non-serif 'I' for the phrase 'I must'), farming the lines out to underlings or altering your handwriting so that 'I must not' starts to look like 'I must'. These may be used successfully by a HighSchoolHustler. Other characters trying this will most likely be caught out and have to redo the work properly.

This has become something of a DiscreditedTrope, as using this as a discipline has fallen out of favor, since many teachers have complained that it has a negative impact on students as it turns writing (something which makes up a bulk of the school curriculum) into a punishment. However, depending on the teacher, it still sees application today in uncommon instances.

A variation on this trope is occasionally seen, in which the repeated line is to be spoken (in a deadpan mutter) instead of written.

Distinct from MadnessMantra and/or RoomFullOfCrazy in that this is enforced as a punishment on someone, not something a character does of their own decision.



* A UsefulNotes/McDonalds commercial from 1987 features the Hamburglar stealing hamburgers from Ronald's class. At the end, he is caught and is forced to write "Don't take burgers [[CatchPhrase rubble rubble]]".
* In a commercial for the [[UsefulNotes/SuperNintendoEntertainmentSystem SNES]] Super Set features a math teacher showing how the SNES gives you [[VideoGame/SuperMarioAllStars four games in one]] while the UsefulNotes/SegaGenesis gives you none. At the end, a dumb student [[TakeThat who likes Sega]] is forced to write the Nintendo slogan "The best play here."

[[folder:Comic Books]]
* In ''ComicBook/SupergirlCosmicAdventuresInThe8thGrade'', ''[[ComicBook/{{Supergirl}} Linda]]'' is sentenced to write "I will not whine about my life in Science Class" after being caught dozing off. She tries to use her super speed to get it done in no time, but unfortunately she puts her hand through the blackboard... and the wall.

* ''Film/MontyPythonsLifeOfBrian'' features a scene where Brian is caught by a Roman centurion while he's writing ROMANES EUNT DOMUS on the wall of the amphitheatre. The centurion couldn't care less what the actual message is, he just wants to [[DoWrongRight tell Brian off]] for his [[YouMakeMeSic poor Latin grammar]] ("The people called Romanes, they go the house?") and deliver a [[SternTeacher strict Latin lesson]]. Brian is then told to write the corrected message (ROMANI ITE DOMUM, "Romans, go home!") 100 times on the wall before sunrise (which is seen by his fellow rebels as a far more courageous protest than the minor act of graffiti expected of him). But then a less eccentric patrol sees him admiring his work, paint in hand, and RealityEnsues.
* ''Film/TheMightyDucks'': The entire Ducks team is detained for quacking at the principal.
* Cyclops in ''Film/XMenOriginsWolverine'' is sentenced to this after refusing to take off his sunglasses in class.
-->'''[[http://comicsalliance.com/comicsalliance-reviews-x-men-origins-wolverine-2009-part-o/ Chris Sims]]''': Hes writing I will not leave this franchise for [[Film/SupermanReturns a Superman movie]] a hundred times.
* ''Film/TheShining'': Suffering from boredom and writer's block, Jack types "All work and no play makes Jack a dull boy" repeatedly just so he can give himself the illusion of progress, but eventually it turns into a MadnessMantra.

* ''Literature/HarryPotter'':
** Draco Malfoy ''expects'' this punishment for breaking curfew in the ''[[Literature/HarryPotterAndThePhilosophersStone Philosopher's Stone]]'', but instead has to go with Harry and Neville to help Hagrid locate a wounded unicorn... in the Forbidden Forest... at night... while whatever attacked the unicorn is still wandering around in there. (Keep in mind he's ''eleven years old,'' and much more sheltered than Harry is.)
** The infamous detentions with [[Characters/HarryPotter Professor Umbridge]] in ''[[Literature/HarryPotterAndTheOrderOfThePhoenix Order of the Phoenix]]''. Harry is forced to write with a quill that doesn't use ink, but as you write, the words are ''etched onto your hand'', and the writing appears on the paper in ''your own blood''. He still has the "I must not tell lies" scar in the last two books. And the wound proper doesn't appear the first time: for Harry to receive the scars, he had to write the line several times, every night of the week, on several occasions.
** In their [[Literature/HarryPotterAndTheHalfBloodPrince sixth year]] Seamus is set to write "I am a wizard, not a baboon brandishing a stick." After accidentally producing a spout of water that hits Professor Flitwick in the face while talking and waving his wand around.
** After becoming a prefect, Ron fantasizes about catching Gregory Goyle (one of Malfoy's mate) for something, so that he can make him write lines, which he figures would kill him since he's so stupid. He'd have him write "I must not look like a baboon's backside."
* In Creator/GordonKorman's book ''[[Literature/MacdonaldHall The War With Mr. Wizzle]]'', the new PointyHairedBoss of an assistant principal introduces lines as a standardized universal punishment (as his job is to modernise the school, the irony of this is immediately lampshaded). The students retaliate by picking a handful to write everybody's lines for them, giving the other students time to sabotage Wizzle's computer, make an InventedIndividual, and so on. (The kids who get picked to do lines soon begin to resent the ones who got assigned to the fun stuff, but they prevail anyway.) By contrast, the Headmaster, Mr. Sturgeon, whose power the students respect, disapproves of lines and prefers to impose lengthy essays as punishment.
* One of the protagonists of ''Literature/WitchWeek'' by Creator/DianaWynneJones is assigned lines. He tries to invent a spell that will animate a pen to write them for him; it works, sort of, but the pen doesn't remember which order the words are supposed to go in, so he has to rewrite them by hand. Also, if he's discovered by the wrong people, he'll be burnt as a witch.
* Sethra Lavode punishes one of her followers this way in ''Literature/{{Yendi}}''. The character had been involved in some really evil plotting, but was too valuable to TheEmpire to kill. Sethra exiles her to a timeless desert "pocket dimension", and has her write "I will not interfere with the Dragon Council" 17 x 17 x 17 x 17[[note]]Equals 83,521[[/note]] times in the sand. (17 is a sacred number in their culture.)
* In ''Literature/{{Frindle}}'', to make the students stop referring to pens as "frindles", the teacher makes them stay after school and write "I am writing this with a pen" one hundred times. The students make a game of seeing how many times they can get away with changing the sentence to "I am writing this with a frindle" without the teacher noticing.
* George and Harold from the ''Literature/CaptainUnderpants'' series have been punished this way so many times that they keep a set of poles in their backpacks they put several chalksticks into to write multiple lines at once.
* In the autobiographical ''Homesick: My Own Story'', Jean Fritz says she would write fifty "I"'s, fifty "will"'s, etc so she wouldn't have to think about what she was writing, because she wasn't really promising not to talk in class.
* Parodied (unsuprisingly) in the ''Literature/{{Discworld}}'' book ''Discworld/TheLastContinent''. The Bursar recalls a fellow student wizard who invented a machine to write lines for him, however preparing the machine and winding it up took far longer than it would to write the lines (this is a sign of Progress). Nevertheless, other students would queue up and pay to use it, until an experimental multi-quill version exploded.
* ''Harry and the Wrinklies'', about a boy adopted by a retirement home full of well-meaning ex-cons, has an amusing occurrence: Harry is unfairly given lines as a punishment, so the resident forger tells him to just do half a dozen and he'll print off the rest.
* In ''[[Literature/KushielsLegacy Naamah's Curse]]'', Moirin's penance, set for her by the Patriarch of Riva who is holding her prisoner, is that she must scrub the floor of the cathedral, on her hands and knees, with a very small scrub brush and a bucket of lye. For each floor tile, she must recite the line "Yeshua the Anointed, Son of God, have mercy on me, a sinner." It's a very large cathedral.
* In the 1956 young-adult novel ''Danny Dunn and the Anti-Gravity Paint'' by Raymond Abrashkin and Jay Williams, Danny's teacher, in an effort to get him to stop daydreaming about space travel, makes him write "Space flight is a hundred years away" over and over. Before he can begin the assignment, the spaceship his friend Professor Bullfinch has secretly invented is accidentally lauched, with Danny and friends aboard. They make it back to Earth and Danny presents the assignment to his teacher, having finished it during the voyage. She humbly says she'll keep it as a souvenir.
* A variant in some older British school stories is that the offender is made to copy out lines of poetry. This crops in, among others, ''Literature/ThePrimeOfMissJeanBrodie'' and ''Literature/StalkyAndCo'' (In the latter, SadistTeacher Mr. King gets a rare PetTheDog moment when he reads out Virgil's ''Literature/TheAeneid'' to a student who's been sentenced to write out several hundred lines of that work. Really it's just an excuse for keeping the lad company and taking his mind off the upcoming ordeal: the detention means he will miss games practice and thus get caned.)
* Mentioned in ''Literature/{{Jennings}}''. In the first book, when Temple is giving a comically exaggerated impression of Mr Wilkins to scare the NewMeat, he says that he had to write out "The angles at the base of an isoceles triangle are jolly nearly equal" 150 million times. Darbishire takes this literally and tries to work out how long it would take, eventually arriving at a figure of just over 47 years.
* ''Literature/SpaceCadet''. One of the cadets resents being pulled up over his lack of table manners, and when told to eat his pie with a fork instead of his hands, insists on getting the order in writing as per regulations. The senior cadet does so without complaint, then gives him another written order telling him to report to his commanding officer. He gets a roasting, and an explanation of [[OfficerAndAGentleman why such petty matters are necessary]], and an order to write out two thousand times, "I will eat my pie with my fork."
* In ''[[Literature/MrsPiggleWiggle Missy Piggle-Wiggle and the Won't-Walk-the-Dog Cure]]'', Missy's possible boyfriend, Harold Spectacle, expresses appreciation at how creative her cures are after she successfully administers the titular Won't-Walk-the-Dog Cure, which involves turning the child's dog into a talking dog which is placed in charge of caring of the child, but shirks the responsibility. He notes that when he was a child, a teacher once tried to correct his behavior by making him write 100 lines on a chalkboard, but it only made him hate chalk.
* ''Literature/LePetitNicolas'': The class is usually punished at the same time, so one story has them stuck inside on a beautiful afternoon (French schoolchildren used to have Thursday afternoons off except for detentions) all writing lines under a teacher's supervision (who would clearly much rather be home). One kid starts to ask a question and is told to be quiet, but when the class is nearly done an hour or so later, it turns out he was asking if he could borrow a pen. The teacher actually sits down and starts doing the kid's lines for him, and when the class leaves they run into the principal... [[HereWeGoAgain and one kid accidentally gets the whole class in detention.]]

* In ''Series/OurMissBrooks'', it happens at the end of "Spare That Rod". Walter Denton, Stretch Snodgrass, and teachers Mr. Boynton and Miss Brooks, are forced to stay until 7:00 in the evening, writing out "Our principal is the best principal that any school ever had."
* Italian ComedicSociopathy series ''Series/CameraCafe'' has [[TooDumbToLive Paolo]] ending up this way because he screwed with [[TheUnfairSex the girls in the office]].The result is this trope, but on a paper sheet lying on the floor. An enormous one, at that. It covers [[UpToEleven the whole corridor]].
* In ''Series/{{Warehouse 13}}'', Artie makes Claudia fill a blackboard with "I will not disobey Artie" after she almost destroys the Warehouse by using a magnetic coat [[ItMakesSenseInContext to change a lightbulb]].
* In one episode of ''Series/SoWeird'', Annie and Jack get trapped in a magical version of detention by an artifact until they can learn to get along with each other. One of the assignments is to fill a blackboard with lines. A blackboard that covers every inch of the courtroom. They're understandably sore after it's over.
* Tootie is given this assignment in an episode of ''Series/TheFactsOfLife''. She tries to get away with writing the sentence only once and putting ditto marks (") under each word for the rest of them. Needless to say, it doesn't fly.
* ''Series/KamenRiderFourze'' has the students in Sunday Detention writing the kanji "reflection" a thousand times. Gentaro, on the other hand, needs to do his with a calligraphy brush.
* On ''Series/TheCosbyShow'', Dr. Huxtable gets it from one of his kid's teachers, and when he starts, the teacher tells him to not write big as she's onto that one. Cliff instead writes in teeny tiny letters.
* In the ''Series/{{Supernatural}}'' episode [[Recap/SupernaturalS02E21AllHellBreaksLoosePartOne "All Hell Breaks Loose, Part One" (S02, Ep21)]], the Acheri demon has filled the chalkboard in the one room schoolhouse with the line I will not kill written over and over again. She does not seem to have learned her lesson.
* One episode of ''Series/TheWeakestLink'' had Anne Robinson order a teacher who had been voted off by the other contestants to write on the blackboard many times, [[{{Catchphrase}} "I AM the Weakest Link!" Goodbye!]]
* PlayedForLaughs during the ''Series/MythBusters'' "''WesternAnimation/TheSimpsons''" special. While Jamie, in the foreground, explained why they wouldn't be using cherry bombs for the in-shop tests, Adam was in the background writing "I will not set off cherry bombs in the shop" on a blackboard.
* The poster sent to fans who joined the fan club for the ''Series/ImaginationMovers'' depicted the four movers, Rich, Scott, Dave and Smitty against a blackboard on which they had written several times "I will think big! I will reach high! I will work hard! I will have fun!", which was essentially a variation of their CatchPhrase, "Reach high, think big, work hard, have fun."

* One of the covers of ''Magazine/{{Mad}}'' #481, which spoofed ''Film/TheSimpsonsMovie'', parodied Bart Simpson's writing of lines with Alfred E. Neuman as Bart writing "I WILL NOT USE THE SIMPSONS MOVIE TO SELL MAD".

* The VillainProtagonist of Music/TheBeatles' "Maxwell's Silver Hammer" is ordered to do this by his teacher. He decides to murder her instead.
* "I Must Not Chase the Boys by Music/{{Play}} shows one of the girls writing the title phrase repeatedly.

* Happens constantly to Jason in ''ComicStrip/FoxTrot''. He tried to automate it with a C++ program twice; once by printing out the lines with the computer to tape it to the blackboard, and once by writing the program directly in chalk. Miss O'Malley didn't accept either attempt.
** Jason has even written lines ''in advance'', such as "I will not throw paper airplanes during assembly" the day before the actual assembly, explaining he had a doctor's appointment after school and couldn't stay late.
* ''ComicStrip/TheFarSide'' had a caveman writing "I will not act primitive in class."
** Also, a young Doctor Frankenstein writing "I will not play in God's domain."
* Happened once to Iggy in ''ComicStrip/{{Heathcliff}}'', after what appeared to be a disastrous show-and-tell day at school: "I will not bring Heathcliff to school anymore."

* In ''Theatre/DamnYankees'', Applegate punishes Lola for her [[MinionWithAnFInEvil conscientious failure to seduce Joe]] by asking her to repeat "Never feel sorry for anybody" one hundred times. She repeats the line, but with no show of penitence.
* At the end of the second act of ''Theatre/MaryMary'', after one of Mary's stupid remarks drives her ex-husband out of his own apartment into the winter night, Mary starts repeating "I must keep my big mouth shut" to herself "mechanically, like a child writing 'lines' as a punishment" (as the stage directions put it).

* ''VideoGame/RevolutionX'' has this in its AttractMode, with the BigBad Helga standing in front of the board. All the lines are things one must do to progress.

* A key gameplay mechanic in ''VideoGame/SkoolDaze'' (and its sequel ''VideoGame/BackToSkool'') - get caught misbehaving and you are given lines; earn too many and it's game over.

* In [[http://www.the-whiteboard.com/autobutton11.html this strip]] of ''Webcomic/TheWhiteboard'', after Roger pushes [[ShmuckBait a button labeled "For the love of God do NOT push this button"]] that gets Doc [[PieInTheFace plastered with thrown creme pies]], he's forced to repeatedly write "I will not push the button again" on a blackboard.

* ''WesternAnimation/TheSimpsons'':
** Bart writing lines on the blackboard in the opening credits of each episode, with the actual lines [[CouchGag differing from episode to episode]]. Including the movie in which the line to write is "[[DigitalPiracyIsEvil I will not illegally download this movie]]".
** In "Lisa's Date with Density," when the music teacher, Mr. Largo, makes Lisa write lines after class, Nelson suggests saving time by using the music staff chalk holder to write five lines at once.
--->'''Lisa:''' [[LampshadeHanging I don't know how Bart does this every week.]]
** Another Lisa example: In "Grift of the Magi", when Springfield Elementary is bought out by a toy company, the new teachers make Lisa write "I will not do math in class" after class when they catch her writing Venn Diagrams instead of pitching new toy ideas.
** In "Separate Vocations", when Bart was punished for stealing the teacher's books (he was TakingTheHeat for Lisa, who was in a rebel phase because a vocational test said she'd be a housewife), he wrote that he'd not expose the teachers' ignorance.
** In "Itchy & Scratchy: The Movie", Mrs. Krabappel makes Marge write "I will try to raise a better child". When Marge questions the value in doing this, Mrs. Krabappel simply tells her, "Just do it!"
** In the introduction to "The Parent Rap," Bart writes "Nobody reads these anymore," and for "Bonfire of the Manatees," "Does any kid still do this anymore?" as a reference to the increasing rarity of these as the show progresses, as well as becoming a DiscreditedTrope in general.
** In "Skinner's Sense of Snow", Bart even gooses Principal Skinner into doing this, who then complains about how it's making his hand lock up. Bart then replies that he's been doing that so long that the bones in his hand and wrist "sound like a cement mixer" (complete with [[{{Squick}} unnerving sound effects]]).
*** Skinner was also goaded in "Please, Homer, Don't Hammer 'Em", where Bart learned about his allergy to peanuts. (Or as Comic Book Guy described it, his [[KryptoniteFactor kryptonite]]) His line: "A baby beat me up".
** In "Marge Vs. Singles, Seniors, Childless Couples and Teens, and Gays", Bart begs Mrs. Krabappel to let him stay after school and write something on the chalkboard 1000 times so he doesn't have to go home and listen to a Roofi song that Maggie is addicted to. He even tells her that he should be punished for giving the gerbil coffee. Mrs. Krabappel tells him, "We all got tired of that chalkboard years ago. Now go home!" Around this time, the amount of chalkboard gags was reduced.
** For the [[MilestoneCelebration 500th episode]], "At Long Last Leave", it's actually Milhouse writing the lines. The phrase: "Bart's earned a day off".
** In "Love is a Many-Strangled Thing", when a therapist tried to [[ScareEmStraight make Homer stop strangling Bart]], Homer was turned into Bart's punching bag. Bart forced Homer to write a claim that he's an adult afraid of his own son.
** When Mrs. Krabappel's actress, Marcia Wallace passed away, [[Main/TheCharacterDiedWithHim the character was retired]]. The episode, "Four Regrettings and a Funeral", [[Main/InMemoriam which was dedicated to Wallace's memory]], begins with Bart writing sadly a single line that says, [[TearJerker "We'll really miss you Mrs. K."]]
** In "The Kids Are All Fight", Lisa is writing lines, "I will not pay my sister to do my punishment" while Bart watches.
** In "How Lisa Got Her Marge Back", Skinner writes lines while Bart watches. His phrase: "Never lose a bet with Bart Simpson."
* A parody of ''WesternAnimation/TheSimpsons'' intro on ''WesternAnimation/{{Histeria}}!'' has Loud Kiddington writing "I do not need a megaphone!"
* Ms. Barch of ''WesternAnimation/{{Daria}}'' will often assign lines to male students because, well, [[DoesNotLikeMen they're male]].
* ''WesternAnimation/{{Doug}}'' imagines doing this until he's an old man, then his teacher orders him to do it again.
** After Doug flips the script on Roger after the latter got the former and the rest of the class kicked out of the news in the same episode, Roger has to do this as punishment as well.
* The pilot episode of ''WesternAnimation/InvaderZim'' has Miss Bitters ordering Dib to write that Zim is not an alien.
* The first ''WesternAnimation/ChalkZone'' episode has Rudy writing "Cartoons are not funny" over and over on the blackboard, until his piece of chalk breaks. The next stick he grabs is the [[MacGuffin magic chalk]], and you know the rest.
* WesternAnimation/TheFairlyOddParents special ''WesternAnimation/ChannelChasers'' has the inevitable Simpsons parody in which Timmy writes on the blackboard, "This is the sincerest form of flattery."
* Tex Avery's "Ventriloquist Cat" opens with the title feline writing "I hate dogs" over and over again on an alley fence, until he realizes he's just written it on Spike the bulldog.
* One ''WesternAnimation/WinxClub'' episode had Griffin, headmistress of a school for witches, temporarily neutralize the Trix by trapping them in a pocket dimension they would be able to leave only after passing several tests and writing various lines on a living blackboard. With one of them being very skilled in illusions ''and'' very knowledgeable about the subjects, it kept them busy for barely five minutes, much for the blackboard's chagrin.
* ''WesternAnimation/PhineasAndFerb'': During SensitivityTraining, Major Monogram was forced to write "Animals are people too".
* In the ''WesternAnimation/CatDog'' episode "Back to School," Cat writes "I will not start food fights" in a chalkboard for the food fight incident.
* In the ''WesternAnimation/FostersHomeForImaginaryFriends'' episode, "Crime After Crime", Mr. Herriman makes up new rules so that no one will suspect his [[ICantBelieveItsNotHeroin carrot addiction]], one of which involves not standing on rugs. Wilt stands on a rug upon hearing this new rule, and throughout the episode, tries to decide on how to punish himself. One of these punishments involves writing "I will not stand on rugs" on the chalkboard repeatedly.
* In the ''WesternAnimation/HeyArnold'' episode "Full Moon", Arnold is forced by Principal Wartz to write "Mooning is not funny" on both a sheet of paper and on the blackboard when he chooses not to identify Sid, Harold, and Stinky as the ones who mooned the principal.
* The ''WesternAnimation/DextersLaboratory'' episode "Dexter Detention" has Dexter and the other students in detention writing [[FelonyMisdemeanor "I Am A Criminal"]], with some writing it pretty wrong. Then Dexter decides to use the chalk to devise an escape plan [[EveryoneKnowsMorse in Morse code.]]
* In ''WesternAnimation/DastardlyAndMuttleyInTheirFlyingMachines'', the ''Magnificent Muttley'' segment "Leonardo De Muttley" begins with Dick Dastardly ordering Muttley to write "I will mind my own business" 100 times on a blackboard.

* ''VideoGame/MoshiMonsters'': In one of the magazines, [[{{Sleepyhead}} Humphrey]] had to write lines saying "I must not fall AsleepInClass". He fell asleep anyway, [[{{Irony}} while writing them]].
* ''Literature/WhateleyUniverse'': In their eponymous story, The Three Little Witches have to copy out the Whateley Code of Mystic Ethics twenty times, and as the Code of Ethics is five pages long, it's a hundred pages.

* [[http://mrob.com/pub/math/numbers-22.html#lynz_K Adam Clarkson]] was told to write a hundred lines. If he didn't finish by the end of the day, that number would double. After over half a year, it had reached 10^19 lines, and he was told that if he didn't finish them that day, it would be squared. That was in 1998. It's now much, much more than a googolplex.
** By October 16, 2007 the number became larger than 10^10^''1000''. (The next major checkpoint, 10^10^10000, will only be achieved on August 24, 2089.)
* Cadets at the United States Military Academy (and several other military schools in the US) perform a variation of the trope when they get in trouble. Instead of writing lines, they march back and forth in a courtyard on the campus. Presumably part of the deal is they have to maintain proper marching form while doing so, which can be ''exhausting''.
