Anime and Manga
- Ranma ½:
- Shampoo feeds Ranma hypnotic dim sum that, thanks to an accident, leaves him with the uncontrollable urge to hug anyone who sneezes. This, of course, occurs just as there's a cold going around the Tendō household.
- Much later in the manga, Ranma uses hypnotic incense on Ryōga to make him confess his love to Akari (showing that Ranma doesn't learn from his own experiences). To this end, since Akari adores pigs, he conditions Ryōga to give a hug whenever he hears the word "pig". Of course, shortly thereafter Akari swears to never talk about pigs again, and Ryōga keeps stumbling on people saying "pig" in more and more ludicrous circumstances.
- It should be noted that the traditional method does not actually work on Ranma in the manga (Happosai's friend tried it and Ranma mentions that mind tricks like that do not work on him), only those done by magical means work.
- In One Piece, Jango the hypnotist often hypnotised himself, as well as his target(s); he eventually gets better at leaving himself out of it. Later in the same Story Arc, Jango hypnotizes the rest of his crew to be incredibly strong; unfortunately, he also hypnotizes Luffy... who goes on a rampage and beats the living shit out of ninety percent of Jango's pirate crew. If you look, you'll see that Jango doesn't actually figure out how to not hypnotize himself, but rather learns to pull his hat down at the last moment so he's no longer watching the swinging disc. Occasionally, he forgets to do this.
- In the first episode of the comedic hentai anime Nageki no Kenkô Yûryôji (distributed in North America under the title F3 (Frantic, Frustrated and Female)), main character Hiroe is given a poorly-phrased post-hypnotic command by her sister Mayaka — and as a result has an orgasm each time Mayaka touches her.
- In Kimagure Orange Road, sometimes Kyosuke would try to use his psychic powers to hypnotize eiher himself (by looking into a mirror and use his skill) or others. Hilarity Ensues.
- The main character Ren from Lost+Brain has a classmate sit in at a hypnosis demonstration and try to resist its effects. The classmate is hypnotised anyway, and Ren manages to learn how to control people even when they aren't in a trance.
- Nanapon from Seven of Seven can hypnotize people with her crystal. In one episode, she tries to teach Nana how to do this, but ends up hypnotizing herself.
- When Isidro of Berserk trips and accidentally grabs Schierke's breast, which he calls small, she responds by using magic to make him act like a monkey.
- In Code Geass, this happens to Princess Euphemia, who Lelouch offhandedly tells to 'kill all the Japanese' when explaining the nature of his Geass to her. She is forced to do so, despite her resistance because of her moral fiber, and is remembered as the Massacre Princess.
- In The Hating Girl, Ryouji accidentally does a child regression hypnosis on Asumi, causing her to start acting like a mischievous toddler.
- The movie Office Space uses this trope cleverly: Peter is put into a relaxation trance, and then the hypnotist dies of a heart attack before he can bring Peter out of it. As a result, Peter remains free of stress even as his boss is frantically calling him to come in to work and stops caring about his job, which ironically leads to a promotion.
- In the film The Curse Of The Jade Scorpion, a hypnotist uses this to control the people behind various security systems. At the end of the film, one of the secondary characters lampshades it by pointing out that said people must have a little larceny in them— otherwise, the hypnotism wouldn't have worked.
- Used at the beginning of the Barbra Streisand musical On a Clear Day You Can See Forever, which had been in its turn based on a Broadway musical. Not only does Daisy Gamble completely submit to the hypnotist's commands (issued to the on-stage volunteer), she even continues to obey his suggestions when the hypnosis has been lifted (she takes off her shoe when she hears the word "Wednesday.") As hypnosis is the main source of Phlebotinum in the film, which includes unconscious regressions into past lives, this is handwaved by the explanation that the main character is particularly susceptible to hypnotic suggestion.
- In The Court Jester, the protagonist becomes the world's best fencer this way.
- The Ginger Rogers / Fred Astaire film Carefree has Fred, as a psychiatrist, hypnotize Ginger and cause all sorts of crazy antics, as he keeps leaving her on her own. Eventually, when he finds out that she has fallen for him, he hypnotizes her not to be in love with him, and tells her that "men like him should be shot down like dogs!" which leads to further crazy antics involving her chasing after him with a gun.
- This was performed in a short from The Three Stooges.
Shemp: (to Moe) You are now...in SING SING!Moe: (Picks up a chair by the rungs, like jail bars) I am now in Sing Sing.
- In the Woman in Green, Watson is hypnotized after declaring the whole thing to be fraud. He comes out of it wondering why he's no longer wearing shoes or socks. Later on the trope is Subverted by Sherlock Holmes after the same hypnosis fails to do anything to him.
- In The Manchurian Candidate, Shaw, not quite the eponymous candidate, but the Manchurian Agent, jumps into a lake at the suggestion (not meant for him) of a bar patron after he accidentally triggers a hypnotic suggestion. The bit about "not acting against one's moral fiber" is Lampshaded and Handwaved by the Communist hypnotisers at the beginning of the movie.
- Merritt specializes in creating these in Now You See Me.
- In the thriller Stir of Echoes, the hero is being hypnotizes as a joke, planting a post-hypnotic suggestion that he be more "open" to everything, which causes his latent psychic powers stop being latent.
- In Unconscious, Salvador tries to hypnotize Alma but accidentally ends up hypnotizing himself instead, with catastrophic (and hilarious) results.
- As a film involving hypnosis, this does come up in Trance, although it is taken ''very'' seriously. For one thing, you'd have to want to be hypnotized first, but when it's performed by the film's hypnotherapist it's outright stated to be a very serious breach of ethics in her profession as is her relationship with her patient Simon. Also, doing so was considered a desperate move on her part, and there were unforeseen side effects such as Simon mistaking a random woman for his ex-girlfriend and murdering her in a fit of rage.
- Literary (1959), and then movie (1962), example: The Manchurian Candidate. Having fallen under hypnosis quite by chance, Raymond Shaw promptly and unquestioningly obeys the suggestion that wasn't even meant for him: "Why don't you go and take yourself a cab and go up to Central Park and go jump in the lake?"
- Richard also literally jumps in a lake—well, a canal—in response to a trigger planted by the titular Dirk in "Dirk Gently's Holistic Detective Agency". Dirk was demonstrating to Richard why exactly one must Beware of Hitchhiking Ghosts, particularly when there's an Absent Minded Professor about in the bad habit of leaving his time machine unlocked...
- In Heinlein's Double Star, the hero claims he's immune to hypnosis, goes out like a light, and wakes up while STILL disbelieving that he was hypnotized until the results are convincingly demonstrated.
- Likewise, in Starship Troopers Johnny Rico is put to sleep by a post-hypnotic suggestion command phrase without even realizing it.
- And again in Time for the Stars, Tom and Pat Bartlett are hypnotized (while falsely thinking that they're under the effect of drugs) in order to bring out their telepathic abilities.
- And yet again in Citizen of the Galaxy, where Baslim hypnotizes Thorby into remembering long speeches in foreign languages so he can later identify himself to Baslim's friends.
- And yet again again in Space Cadet; the hero is subjected to an hypnotic lesson in the Venerian language. He emerges from it feeling unchanged, and is convinced that he was never hypnotized at all until he returns to his quarters and starts amiably cursing his Venus-born roommate — in fluent Venerian.
- The Wayside School books featured a hypnotist who loved to play pranks on his customers. For example, he hypnotized a woman to quit smoking, but added the suggestion that she slap her husband whenever he said "potato". Later there's a Brick Joke where one of his pranks bears fruit after the reader has stopped looking for it.
- Harry Potter: Ron is still hopping several minutes after the Imperius Curse is lifted from the practice session.
- This is the whole point of Captain Underpants: two kids hypnotize their principal into thinking he's a superhero they made up, but their method of ending the trance created a trigger that causes a relapse. Hilarity Ensues.
- In Peter Straub's story "Blue Rose", the young Harry Beever hypnotizes his younger brother to swallow his own tongue. It is implied that soon afterwards, he does the same to a simple-minded man in the neighborhood.
- Cipolla feels offended about not being the first example in this session AND the page quote.
- The Joseph Payne Brennan short story "Levitation" has this end very badly. The hypnotist dies while he commands the levitating, hypnotized man to rise... and nobody can bring him back down.
- In one early Dilbert, Dilbert sees a notice for "Free Hypnotism Lessons" and decides to try it. The last panel shows him in his underwear walking zombie-style:
Dilbert: "A wonderful class. I must tell my friends."
Live Action TV
- In one episode of Monk, Adrian Monk gets hypnotized into thinking he's a child again. He still retains some of his detective skills, but becomes a lot more unfocused.
- On Family Matters, Steve Urkel claims he's so smart he can't be hypnotized. The hypnotist claims that smarter people are actually easier to hypnotize. Urkel scoffs... and is entranced the instant the watch drops. (Comedic aspects aside, and disregarding the "instant" aspects of the gag, this is actually a rare case of Truth in Television being applied to hypnotism).
- Frasier on Cheers hypnotizes Woody to like the vegetable drink he endorsed in a commercial, so he wouldn't have been lying. Unfortunately, the product is discontinued, but Woody is now an addict.
- In that same episode, Frasier mentions the time he hypnotized Lilith as part of a prank, which Lilith denies. She then spends the rest of the episode doing increasingly ridiculous things (like taking off her shoes and breaking into song) every time someone says certain keywords. Naturally this is never mentioned again.
- Specifically: "brie cheese" = take a shoe off, "tambourine" = begin unbuttoning shirt and "tractor" = sing "Tomorrow" from Annie.
- In that same episode, Frasier mentions the time he hypnotized Lilith as part of a prank, which Lilith denies. She then spends the rest of the episode doing increasingly ridiculous things (like taking off her shoes and breaking into song) every time someone says certain keywords. Naturally this is never mentioned again.
- Wings: Brian is able to make the skeptical Joe cluck like a chicken whenever he hears the word "tortilla." However, later Roy admits under hypnosis that he stole the life-savings of an old man and buried it in his back yard. The gang conducts a dig to locate the stash before realizing he was faking it and just wanted someone to dig the hole for his new hot-tub. Turns out, as he had insisted earlier, he really couldn't be hypnotized.
- Neatly subverted in an episode of Perfect Strangers in which Larry claimed to be immune to hypnosis, proceeds to go under with consummate ease — then reveals about a minute later that he's only pretending, and he actually can't be hypnotised. Meanwhile, Balki was accidentally hypnotised just by half-listening from the next room.
- The episode "My Husband Is Not a Drunk" from The Dick Van Dyke Show, where van Dyke's character acts as though he was drunk every time a telephone rings. Established earlier as an easy hypnosis mark, he was hypnotised from another room as he overheard the hypnotist try to hypnotize Buddy, who genuinely couldn't be hypnotized.
- Happened on Gilligan's Island. Mary Ann thought she was Ginger, and hypnosis was tried to cure her and make her think she's Mary Ann again. The hypnosis failed, but worked on Gilligan, who was listening.
- In an episode of The Greatest American Hero, Bill is accidentally hypnotized while watching a hypnotism performance and falls asleep (or instantly wakes up) whenever he hears the word "Scenario".
- In a particularly silly episode of Murder, She Wrote, a hypnotist is killed in front of several eyewitnesses, all of whom he's just commanded to forget everything they've experienced. And also showed why you have to want to be hypnotised...
- An episode of Kate And Allie had a character visiting a hypnotist to handle stage fright, as she was to appear on television later. The hypnotist is interrupted by a phone call from the hypnotist's daughter. The hypnotist takes the call in the other room, but his client can still hear him. His daughter is disappointed because she tried out for the cheerleading squad and got picked as the mascot: a chicken. The hypnotist's advice to his daughter, overheard by his client, is to "cluck like a chicken for all you're worth!" On stage later, she did exactly that.
- On NewsRadio Joe hypnotizes Jimmy to cure him of his fear of hippies. Matthew gets hypnotized too and messes things up until Joe makes him think he's a chicken. Eventually, Jimmy is cured but Matthew remains a chicken. Dave feels Matthew likes being that way — or at least Dave likes him better that way.
- The Fresh Prince of Bel-Air had an episode where Will was hypnotized into acting like a child whenever he heard a bell. The episode ended with a gag where Uncle Phil chastised Will for falling under the hypnosis...and then barking like a dog when he hears a bell.
- Friends: When Rachel wants Chandler to quit smoking, she gives him a tape to play while he sleeps. The tape tells him he is a strong, confident woman who doesn't need to smoke. Over the course of the episode, Chandler is seen exhibiting certain feminine traits such as coming out of the shower with a towel wrapped around his hair and torso.
- Joey then alters the tape so it says "Joey is your best friend. You want to buy him a sandwich every day." The first time Chandler plays the new version, he wakes up in bewilderment.
- Night Court. Bull Shannon is due to appear on a game show but is nervous, so his friends hypnotise him so he will remain calm when he hears a Trigger Phrase which is...unfortunately the lecherous DA Dan Fielding choses that moment to say "I want to be your love slave!" to an attractive prison officer. Ironically Bull handles the game show quite well but Dan, not realising this, rushes onto the stage and shouts "Bull, I want to be your love slave!" on live television. At a press conference Dan excuses his actions by saying he was kidnapped and brainwashed by Soviet agents.
- Though not quite an example, one episode of Boogie's Diner had the boss listen to a tape of "Tibetan Monk's Omming" to calm down. It worked remarkably well. Then the staff realizes they have an excellent severage package and tries to tape over the Oms so he'll fire them. Except they have to do it so it's hard to tell from the actual tape, which means matching the monks' tone of voice. What follows is basically a very serene musical number.
- In The Sarah Jane Adventures, Clyde is victim to hypnosis, and Sarah Jane to scarily accurate predictions, during a visit to a show. Later, Clyde gets hypnotised again, as is the rest of the world, except for Luke and anyone born under the sign of Taurus. Naturally, this being a Doctor Who Spin-Off, it's down to aliens.
- Big Kids — the entire concept of the show. The Parents start frequently acting like young children after a hypnotist's show. In the end, their kids work out that the word which "switches" them is the hypnotist's name, Ming, whether on its own or as a part of longer words. Needless to say, Hilarity Ensues.
- In The A-Team, Sergeant Bosco "B.A." Baracus has a fear of flying. In "In Plane Sight", he is tricked into being hypnotized so that he will fall asleep when someone says "eclipse", allowing him to sleep through an important flight. Later, in combat, Face runs out of ammo and yells "give me clips!" and he falls asleep.
- The plot of one Kenan & Kel episode centred around a bet that Kel couldn't survive one week without drinking orange soda. In an attempt to cure his addiction, Kel goes to a hypotherapist... except Kenan (by this point on the verge of losing the bet) switches the charts and the highly trained hypnotherapist doesn't think twice about hypnotising Kel into becoming a vicious guard dog when he hears the chime of a bell. Hilarity Ensues.
- One episode of Laverne and Shirley had the duo acting like chickens every time they heard a bell ring.
- Round the Twist had a hypnosis episode which resulted in Pete acting like a chicken whenever the word 'now' was mentioned. It also featured a counting chicken which was made to regress (or ascend) to a past life of being a mathematician.
- My Hero combined this with The Fun in Funeral. One episode's A-plot has George Sunday (secretly the superhero Thermoman) being taken for dead as a result of his Bizarre Alien Biology acting up, while the B-plot has Mrs. Raven, the closest thing to a Token Evil Teammate on the show, taking up the kind of hypnosis program which features "You will quit smoking. Then you will start drinking. Then you will come to me with your drinking problem." When the minister is listing George's three traits, we get events such as Pierce clucking like a chicken and Stanley claiming to be Spider-Man. When "These are the things we will remember him for" comes around, we're treated to a rendition of the YMCA by these three; "ten", incidentally, is the chicken dance.
- The Suite Life on Deck had London being hypnotized to act more like Bailey. Naturally, it got annoying, but when the hypnotist tried to change her back, it accidentally affects the daughter of the dean from Yale University.
- In the House episode House's Head, Chase is hypnotizing House to help him remember what happened during a bus crash. House saw Wilson and Amber in the room, so Chase told him to ignore Amber and Wilson. This resulted in the rest of the episode spent trying increasingly dangerous ways of dredging through House's mind. He was finally forced to realize that Amber was the person he was searching for.
- A dramatic example occurs in an episode of CSI. A hypnotherapist manages to convince one of her clients, a bank teller, to give her change for a twenty; however, while she thinks she's counting it out in ones, she's actually giving the hypnotherapist hundred dollar bills. When another client figures this out, the hypnotherapist triggers a command that makes her think she's on a beach vacation... causing her to walk off her balcony.
- Which leads to a conversation when the hypnotherapist tells the officer that she can't make people do what they don't want to. The latter retorts with "I can. Go to jail".
- A rather low-key version appears in the Leverage episode, "The Scheherezade Job". In order for their heist to work, they have Hardison infiltrate an orchestra since he had been a violin prodigy when he was young. He was nervous about not having touched a violin in years, but when his solo comes he plays his part beautifully. The Reveal at the end is that Nate had hypnotized him to return to his childhood level of skill, 'shaking the cobwebs out' as he put it. It still earned Nate a big What the Hell, Hero? from the rest of the team, with callbacks to it in future episodes.
- An episode of The Flying Nun has a dentist cross this one with a bizarre "Freaky Friday" Flip: He uses hypnosis to make Sister Bertrille and the Mother Superior think they're each other. Hilarity, of course, ensues.

Then he has a meeting with a Russian interested in the US radio market, who is a Colonel in the Russian army. His translator is named Buck Sanders. Hilarity Ensues.
- In Whose Line Is It Anyway?, one session of the game "Let's Make a Date" has Ryan as someone who's "still hypnotised from last night's show". Among the completely random responses he strings together are chicken noises, standing at attention with his pants around his ankles and saluting.
- There was running gag between Colin and Ryan on the show where one of the two would say something embarrassing and then say, "Sleep", causing the other's head to slump. Example: when Colin makes an awkward statement about how much he likes women, he then tells Ryan, "Sleep. You will forget everything I said. Wake." Later, when Ryan stumbles over what he's trying to say, Colin says, "Sleep. When you awake you will have perfect diction. Wake."
- Top Gear's Richard Hammond was once hypnotised into not recalling how to drive. He was then filmed in a car looking completely baffled as to how anything worked. Later, in the studio, while discussing the experience, an earlier hypnotic suggestion was envoked which made him think a child's pedal car was his own, beloved car and that he would get unreasonably enraged when anyone damaged it. As he pedaled around the studio, Jeremy Clarkson got into another pedal car and ran into him. Hilariously, Hammond's road rage over the 'damage' amounted to little more than blustering "You ran into me!" in disbelief.

- An episode of The Mentalist deals with hypnosis. Rigsby ends up assaulting a suspect during interrogation and then not remembering the act. Jane determines that he's been hypnotized. When it's pointed out that people can't be made to do things that go against their nature, Jane agrees that this applies to normal people. However, Rigsby is hardly a pacifist, so he can be hypnotized to do violent things.
- One Dave Allen At Large sketch shows a nightclub hypnotist summoning an attractive young woman to the stage. She slowly puts her into a trance, and then tells her to take off her clothes. She snaps out her trance, calls him "fresh", slaps his face, and walks back to join the rest of the audience ... who are all stark naked.
- Darren Brown, as part of his The Experiments series, tested the old legend of hypnotically trained assassins who were conditioned to performed murders without the assassin's knowledge, with a series of tasks being performed to slowly condition a man to become a better marksman, react to visual stimuli to enter trances and to respond to assassination requests made by people who play a ringtone. The assassin successfully assassinated Stephen Fry!

- At least this one◊ in Jason Love's cartoons warned about consequences
- An episode of The Flintstones had Fred hypnotize Barney by accident (he was standing behind him) during an (unsuccessful) attempt to hypnotize Wilma.

- In a Recess episode, Principal Prickly was accidentally hypnotised into thinking he is six years old again, whereas the intended target (Miss Finster) is unaffected.

- The Penguins of Madagascar had one episode where Private tried to help a petting zoo sheep (who hated being petted because the people petting him never washed their hands which made his coat dirty and sticky) by hypnotizing him into not minding the petting.

- Wade Duck was the target of this twice in the U.S. Acres segments of Garfield and Friends: once on purpose to remove his fears, another by accident for humor.
- One, "Wade, You're Afraid," had him hypnotized to be fearless, but this turns him into a Jerkass and ready to take on the farm's bull by making insults to it. It was adapted from one of the weekly strip arcs.
- Another one, "Dr. Jekyll and Mr. Wade," had Wade Duck also do the listening-in accidental-hypnosis thing: Orson, Booker and Sheldon were outside the barn having a casual discussion of hypnosis and somehow accidentally hypnotize a listening-in Wade who was on the other side of the barn wall. Whenever he heard a bell he would become a vicious monster. Later the hypnosis helps him save his friends (who never witnessed the event, mind you, because the random noise of any bell would turn him back to normal) by beating up Orson's bully brothers when they ring the dinner bell to turn him into that monster.
- Likewise, in The Garfield Show, in order to get Garfield to work at Doc's farm, Jon gets Dr. Whipple to hypnotize him into becoming an enthusiastic hard-working cat every time he hears a horn, and back to his lazy self when he hears another one.

The rest of the episode consists of his friends trying to prevent him from killing the farmer until they resort to making a farmer-shaped model out of hay and tricking him into destroying it, which finally releases him from the hypnosis.
- Lilo & Stitch: The Series had an activated hypnosis experiment named Swirly cause trouble on the island by putting Lilo in a trance who upon hearing an accidental suggestion from Pleakley started to act like her jerkass rival, Mertle, and who hypnotized Stitch into loving a certain television show at the suggestion of the hypnotized Lilo. Much trouble ensues until Jumba puts them out of their trance by simply snapping his fingers and Swirly it put into the place he truly belongs where he hypnotizes guests to act silly at parties, including Mertle into acting like a chicken. Also, Gantu is hypnotized by Experiment 625 into doing anything he's told to do, resulting in 625 and Hamsterviel making him do embarrassing things by making him say he's an idiot with a stupid grin on his face, twirl like a ballerina, and juggle various objects while balancing on a rolling pin.
- Another instance occurred where Lilo finds an experiment named Checkers that grants her the power of command over all living things. She decides to make herself queen and have fun around the house by making Nani and Pleakley grovel and serve her every whim.

- In the Inspector Gadget episode "Quiz Master", the winners of the quiz show are hypnotized in a "cone of seclusion" and commanded to rob armored cars. Gadget falls victim to this as well, but Penny reverses the process and hypnotizes the show's MAD agent host into returning the stolen money and turning himself in.
- In the Victor & Hugo Victor tries to hypnotise himself into becoming a master criminal by aid of looking at himself in a hand-mirror. Unfortunately for him, Hugo is sitting right behind him looking at his own reflection in the mirror, so he is the one who gets hypnotised. To cap it all off, Victor has a cold, so whenever he sneezes, Hugo turns into a tough-talking, hyper-competent gangster but changes back to his usual useless crook self whenever Victor sneezes again - always at the worst possible moment.
- In the "Mad Mod" episode of Teen Titans, Mad Mod uses hypnoscreens to try and hypnotize the Titans which works best on Beast Boy. He drools a lot and becomes rather mindless when this happens.
- News report about a man who hypnotized himself too well using a mirror.
- There are many cases where people have received false memories from out-of-line hypnotists.
- Self-hypnosis* can be dangerous if you let fantasies/fetishes distract you when making your script.
- As noted above, Truth in Television often does not apply here, as many of the effects of being hypnotized depicted in fiction (being unable to lie, being forced to do things against your will, being trapped in a hypnotic state until released, etc.) simply do not apply in real life. If you see someone during a stage show having been hypnotized and then proceeding to act the fool in front of hundreds of people, they had to be willing to do so to begin with. And people will generally come out of any hypnotic trance on their own if left to their own devices.
- About 10 to 15% of people are extremely suggestible. They are known as somnambulists, and can really be put under that easily and quickly. Stage Hypnotists are really good at picking them out. And while they can be made a fool of on stage easily, the whole sleeper agent thing doesn't work, and people cannot be made to do things truly against their will. And while people can be stuck to the floor, if they ever actually end up in danger because of it they will snap out. The stage tricks work because they are actually harmless.
