Thanks for the Mammary



"Ishmael: But what do I say to her, Scobe? [...] Scobie: Thanks for the mammary?"

- Don't Call Me Ishmael!

Alice is perfectly fine. She's walking along, enjoying herself. Out of nowhere, Bob bumps into her and, by sheer accident (we think), grabs her boob. Alice may forgive Bob, but at the same time she could resent him (even hate him) or use this as an opportunity for blackmail. More often than not, however, she will hit him.

The Accidental Pervert is contractually obligated to have this happen at least once, if not Once Per Episode.

Somewhat related to Funbag Airbag. See also Not What It Looks Like. Compare and contrast with Skinship Grope.

Anime and Manga
"*SQRSH* Keiichi: (reaching for an off-panel bag of chips while studying) Huh? Doesn't feel like chips. Did I throw some buns in that bag? Urd: Oh, MY. ♥ Gently, honey... gently."
 * Keitaro of Love Hina has been theorized to have breast magnets in his hands considering how often this happens to him. What usually follows is either a punch (Naru), an innocently/happily surprised "Oh my!" (Mutsumi), a scream (Shinobu), or a blush and an excited giggle (Kitsune).
 * Suzumiya Haruhi gets the computer club president to grope Mikiru against his will (Mikuru does not approve either). Kyon is an accessory to the fact, since he photographs the whole thing so that Haruhi can use the photos for extortion. This was modified in the animation by having Haruhi take the pictures instead, which is terribly amusing since Kyon has absolutely no reason to be in the room when this is going on except to take pictures. As a result, he just stands there acting all disgusted at Haruhi's actions.
 * This happens a few times in Elfen Lied.
 * The first example is when Nyu starts fondling Yuka to sexual excitation.
 * After Kohta accidentally gropes Nyu early on, she sees it as a action of endearment, like a hug. And then she apparently starts to innocently rub herself on his hand, since it apparently felt so good. Cue Kouta's cousin walking to the room.
 * Nyu also gropes and nearly rapes Nozomi because she misunderstood something that Kouta said, making her believe that it was OK to do it to big-breasted people.
 * Neon Genesis Evangelion
 * Shinji and Rei, of course. Though the focus is mainly Rei's creepy non-reaction.
 * Later, in End of Evangelion Gendo seems to purposefully grope naked Rei's chest, and then his hand goes through her like silly putty.
 * Done in a surprisingly abrupt manner by Itoshiki-sensei in Sayonara, Zetsubou-sensei (the episode with the roads signifying different excuses for avoiding responsibility). Occurs with absolutely no lead-up, and his "victim" Chiri tries to pressure him to marry her in order to "do things properly". Worth noting that she demanded marriage even earlier when both she and Itoshiki went to rest in nurse's office unaware of each other and she rolled on his bed in her sleep. She's... pathological (but aren't they all).
 * Early in Full Metal Panic!, Sôsuke performs a Diving Save to prevent Kaname from being hit by a truck... and ends up with his hand on her breast. She actually doesn't notice until Sōsuke gives her a reassuring squeeze... Made at least ten times funnier by the fact that her first reaction is apparently pure delight—which thoroughly shows on her face—for about three seconds. After which she realizes what's going on, resulting in one of the funniest expression changes ever...
 * To LOVE-Ru:
 * Rito also seems to have the breast magnets, although he must have one in his head too, leading to a lot of accidental Marshmallow Hell.
 * Also a rare variant where Rito accidentally grabs Mikan's butt (Thanks for the Glutes?). It proved very popular among the fanbase and lend to a second chapter with more of Mikan getting her ass grabbed by him.
 * Then one of the times Rito was turned into "Riko", Nana accidentally groped his breasts (with a little Funbag Airbag along with it), leading to a fit of jealous rage.
 * Keitaro may have breast magnets in his hands, but Densuke from Eiken is a breast magnet. And most of the girls are affected by the Newtonian "equal yet opposite reaction."
 * In Yu Yu Hakusho, this is one of Yusuke's favorite ways to get on Keiko's nerves, to the point where, when he's possessing someone while temporarily dead, this is the way he convinces Keiko that it's really him. Her tolerance of it (and, at time, complete indifference to it) is one of the many things that signify their Belligerent Sexual Tension relationship.
 * Erio and Caro's first meeting in Magical Girl Lyrical Nanoha had Erio's hands end up in two embarassing places when they crashed in a heap after he caught Caro when she tripped. In a subversion of the usual reactions, the two of them simply disengaged efficiently after a short moment of embarassment and the incident was quickly forgotten. It probably helped that they were both only ten. However, this lead to a Running Gag for the Fan Artists & Doujin Writers.
 * Ranma ½. This may take some time...
 * When Ranma first comes to the Tendô Dôjô, Nabiki proves Ranma's (apparent) gender by first poking her/him in the breast, then rubbing it. She later emphasizes her point by grabbing her/his breast again. And, when it seemed Ranma's bust size had increased in a late manga story, she proved it by... you guessed it! Groping hir again.
 * During Tatewaki Kunô's introduction, he plunged into a pool alongside Ranma. His first hint that something was amiss was when he held onto the latter and accidentally grabbed her breast and squeezed.
 * An anime-only scene in the first season has Sôun try and break up a fight between Ranma and Genma, both in cursed form, by pushing them apart with a hand on each chest. He then promptly realises he's cupping Ranma's breast, and his daughters have seen him doing so. He tries to claim that it's Not What It Looks Like, and promptly catches a fist in the face from Ranma due to not letting go.
 * In another episode of the anime, male Ranma stands up, half-faints, and braces himself. On [[media:accidental grope.png|Akane's chest.]] As expected, a Megaton Punch follows.
 * Sometime in the late manga (and an anime OAV), Ranma has to confront a ki draining teacher, Miss Hinako, whose technique can only be sealed away by hitting three shiatsu points on her chest and two on her back. Not much of a problem when Miss Hinako is in the body of a eleven-year-old girl... a very big problem when she inevitably absorbs his Battle Aura as he's hitting the points, causing her to grow up into a tall and buxom woman, and he gets a handful of breast for all the school to misinterpret.
 * And, of course this is how Ranma discovers that Ukyô Is a Girl.
 * In Nagasarete Airantou, this trope is employed as a fight-winning technique.
 * In To Heart 2, Takaaki falls on Karin and has his hand on her breast. Karin uses this to blackmail Takaaki into joining the UFO Research Club.
 * Mahou Sensei Negima has Negi do this to Asuna a lot. It helps that most of the time it genuinely is accidental. Lucky bastard gets away with it scot-free most of the time, due to his age. Humorously, the one time he gets socked for it is when he does it while magically aged-up.
 * Subverted in Minami-ke when Natsuki, one of Touma's older brothers, gets pushed into Haruka resulting in a grab. Haruka knows perfectly well that it was accidental and does not hold it against Natsuki. However, the incident occurred in front of Haruka's class, so for the sake of appearances she still has to punch him out.
 * In the first episode of Vandread, Dita crashes her dread through the hull of the Male fleet's flagship, and right into Hibiki, throwing her on top of him and knocking them both out. When Hibiki comes to, he's unaware that Dita is still laying on him unconscious and his face is covered by her chest. He grabs a breast and squeezes and exams it for a few seconds, curious as to what it is (Men have had no contact with women for generations in the series). Dita apparently woke up only after he was done, or just wasn't bothered by it. In Dita's case, the later is actually possible.
 * Ed from the 2003 anime version of Fullmetal Alchemist does this to Psiren.
 * Naruto does this in a filler episode.
 * Same with Dragonball Z's Gohan.
 * Happens to Futaba in Futaba Kun Change when he is mistaken for a Chikan on the train. Hilarity Ensues.
 * Ah! My Goddess
 * In the manga, here:

"Yuuto: Himari's are big after all... (Gah, what am I saying!?)"
 * In the OVA video, Urd grabs Keiichi's hand and forcefully presses it against her breast.
 * Omamori Himari
 * Happens to Amakawa Yuuto, mostly with Himari. He seems to have mixed feelings on this...


 * On at least one occasion, he wakes up with her in his bed, with his hand full of boob. Unlike the standard "OHCRAPIHAVETOSTOP!" reaction, he briefly considers massaging it. Then she wakes up.
 * How Sano found out Mizuki's secret at the beginning of Hana Kimi. Mizuki had been knocked out playing soccer with Nakatsu, and guess what Sano accidentally touched when he picked her up? In another chapter, Sano tried to put a hand on her shoulder, but missed.
 * In both the anime and manga version of Ladies versus Butlers!, Akiharu is confronted by Selnia who is convinced from his appearance that he is up to no good. When he decides to ignore her she takes a swing at him, both of them trip and he ends up with his hands on one of her breasts. It wouldn't be so bad if he wasn't so stunned that he was still touching her when she recovered her wits.
 * Happens a couple time by Gourry to Lina in The Slayers. Once when they are laying in a field—Gourry falls asleep and rolls over, his hand landing on Lina—and then in the second season where Xellos grabs Gourry's hand and makes him grab Lina to test a theory. Naturally, pain is involved both times.
 * In Fairy Tail, during a fight with Juvia, Gray freezes her in ice and realizes a second too late that his hand was latched onto her breast when he froze her. Lluvia is embarrassed and delighted; Gray is equally embarrassed and utterly baffled by her reaction.
 * In Gintama, Tsukuyo offers to let Gintoki grope her breasts, he declines, ends up doing it accidentally anyway, and gets a suplex for his efforts.
 * In the first chapter of Tasogare Otome x Amnesia, Teiichi doesn't quite believe Yuuko is a ghost, so he reaches out to grasp her shoulder, reasoning that a ghost will be insubstantial. That's just when she turns to face him, though, so he gets a handful of quite substantial breast. Yuuko is totally unfazed by this. She is a ghost, however.
 * In Bakemonogatari, during one of the times that Araragi is fighting with Mayoi, he gets an accidental handful. She doesn't notice at the time, but is pretty freaked out when he mentions it later ("You stole my first touch!").
 * Happens to Iria in Zeiram the Animation by a kid that fell on top of her.
 * In Nadia: The Secret of Blue Water, this happens when the mobile island the protagonists are atop start shaking violently, and Herton fall on top of Grandis. She naturally responds to this with a Megaton Punch.
 * In A Certain Magical Index, Touma wakes up from his latest misadventure to find his hand grabbing the breast of Little Sister Misaka. At first he freaks about the fact that he's such a pervert that he'd do such a thing in his sleep, only for Little Sister Misaka to inform him he only grabbed her hand, she put his hand on her chest. Touma then realizes that, due to anesthetic, he can't actually feel anything.
 * The main character in Maicchingu Machiko Sensei has this happen to her both accidently and purposefuly Once an Episode... among other things.
 * Inagawa Goro, a recurring character in My Lovely Ghost Kana, frequently expresses a desire to encounter the supernatural. In one issue, he wishes that he could "reach out and touch it," and grabs at the air—while the titular Cute Ghost Girl is floating right in front of him.
 * In Girl Got Game, Chiharu trips and his hand lands directly on Kyo's chest. Since Kyo is pulling a Sweet Polly Oliver, her reaction is not embarrassment, but panic about her secret being uncovered (she had just removed her chest wrappings because she thought she wouldn't need them that day). Thinking quickly, she claimed that her chest was bruised and swollen.
 * In Mayo Chiki this is how Jiro finds out that the resident Chick Magnet is a Bifauxnen and later he does the same to Usami. It should be noted somehow their shirts came undone when he did it.
 * In Freezing happens a few times in the OVA.
 * Also Roxanne gropes Satellizer The Untouchable Queen in first appearance much to the participants of West Genetics shock/horror and accuses her of implants.
 * A non-mammary example occurs in Video Girl Ai. Being played in Yota's broken VCR made Ai's breasts smaller. She tells him that the VCR also turned her into a boy and grabs his hand and puts it between her legs for him to check. After realizing it was just a joke, he laughs but leaves his hand there a just little too long.
 * In One Piece,
 * In Rave Master Elie is running towards the rooms whre Haru is fighting just as an explosion destroys the door and sends Haru flying towards her. He lands with a hand on her chest. She is not amused.
 * In My Hero Academia, the teacher Snipe accidentally bumps his elbow against one or both of Tōru's naked breast(s).
 * Not done by accident in another episode where an injured Mineta fondles Tsuyu after she rescues him; Mineta is something of a pervert. Since they're in a large swimming pool at the time, she responds with the all-too-common teenage tactic of dunking him and holding him under.
 * In the second episode of How NOT to Summon a Demon Lord, Takuma (as Diablo) wakes up and realizes he was not dreaming, and that he actually is Trapped in Another World due to two ditzy sorceresses botching a summoning spell - and then finds out that said ditzy sorceresses are in the same bed with him, and he has his hands on both of their, uhm, assets. Even worse, he isn't able to let go! Naturally, this proves rather embarrassing when his attempt to "order" his hands to do so wakes them up.
 * In the second episode of Yumeria, Tomokazu knocks Mone and Mizuki out of the path of a Faedun attack, and ends up with his hands on their breasts entirely by accident. Not that he minds...

Comic Books

 * Fred Perry's Fan Service Ninja High School comic strip "Minor Adjustments", again. Mimi Masters awakens one morning to find herself blessed(?) with gigantic, gravity-defying Gag Boobs. As she goes with increasing irritation through her school day (she's not happy with them, although others are) the school rich-creep Lendo approaches her to find out if they are real, or due to surgical intervention. To find out, he promptly grabs and honks them both firmly (with an understandable huge grin on his face...). Mimi is not best pleased, and promptly zaps him with one of her magical bolts before storming off...
 * After Scott and Ramona reconcile in Scott Pilgrim Gets it Together, Scott notes the moment to be one he wants to last. Ramona then points out it's been spent with his hand right where the trope expects it to be.
 * In Udon's Street Fighter comic, Rainbow Mika finally gets to face Zangief to a wrestling match. Zangief, who has been pestered by Mika for days, decides to end it quickly with a Banishing Flat. He ends up with a handful of Rainbow Rear End.
 * The page image shows Wolverine doing to Black Cat in the Wolverine/Black Cat: Claws mini-series.

Films -- Live-Action
"Mrs. Teevee: Someone's touching me! Grandpa Joe: (raises hands) Oh, sorry."
 * The Naked Gun
 * Drebin escapes a burning room through the window, climbing along a row of anatomically-correct male and female statues. Between two statues is an open window, and a woman in her underwear just happens to be standing there. Drebin accidentally... well, guess. He then falls off the building, just saving himself by grabbing a statue's stone Gag Penis. In trying to save himself he manages to break the penis off the statue and fall into the woman's room through the window, brandishing it at her.
 * In the sequel, Naked Gun 33 & 1/3, Drebin is at the store squeezing grapefruits to test for ripeness while looking the other way. A woman in a low cut dress walks by, and Drebin mistakes her breast for a grapefruit and squeezes it. He gets slapped.
 * Superbad: Evan is having a conversation with Becca in a crowded school hallway. When someone bumps him from behind, his hand actually punches her in the boob. He's embarrassed, but she assures him it's no big deal.
 * Fierce Creatures: Rollo reaches backwards for a piece of paperwork without looking. He... well, he misses the paper, let's say. Willa takes it in stride.
 * Star Trek (2009). Pre-cadet Kirk during a barfight stumbles "onto" Uhura, much to her annoyance. Kirk puts on his trademark smirk, which Uhura promptly wipes off his face with a sock to the jaw.
 * Simon Birch has the title character doing this. He is a twelve-year-old who (because of his unusual smallness) is playing baby Jesus in a Christmas play, and the person playing Mary (who just happens to be the prettiest girl in the class, who he has a crush on) is bending over him. He reaches up out of the manger and grabs her breast.
 * The Gene Wilder version of Willy Wonka and the Chocolate Factory, during the crowded room scene (paraphrased):


 * Me Myself and Irene has Hank making a very transparent attempt at this.
 * The Jackie Chan film Mr Nice Guy had a scene where Jackie was trying to avoid detection by henchmen, and accidentally copped a feel on Ms. Fanservice while trying to get her to stay close to the wall.
 * In the first Rush Hour, Carter has angered a female cop and walks off. To stop her from attacking Carter, Lee (Jackie Chan) unknowningly presses his hands on her chest. This is subverted, as she was in protective bomb-squad-issued gear for a training exercize.
 * When a character in Kangaroo Jack sees various mirages in the Australian desert, he sees a beautiful woman. Believing her to be another illussion, he gets handsy. In return, the very physically-present woman punches his lights out.
 * Averted in Dude, Where's My Car? in the school camp scene, where a.

Literature

 * The trope naming novel, Don't Call Me Ishmael, contains a scene in which the eponymous Ishmael forms part of a school debating team and, collapsing due to nerves, inadvertently gropes his opposition and eventual Love Interest.
 * In the first Xanth novel, a female centaur offers to give Bink a ride. While she was jumping across a chasm, Bink loses his balance and would have fallen off completely if not for a desperate attempt at grabbing onto whatever he could hold—which, of course, turns out to be her (bare) breasts. She forgives him, saying that she felt him losing his balance and it obviously wasn't deliberate (adding that if it had been deliberate, she'd have dropped him in the chasm).
 * In Hogfather, the newly-created Oh God of Hangovers joins Susan on the horse Binky, and innocently puts his hands around her at an inappropriate height. As he's only existed for a few hours, she doesn't smack him for his ignorance, just corrects his position very firmly.
 * In Carpe Jugulum, the witch Agnes Nitt awakes after the fight with the vampyres in Escrow, to discover the villagers have taken the appropriate local precautions against her waking up as a vampire. (these are many and varied around the Discworld.) She screams that whoever put all those handfuls of poppy seeds down my bra had better have been a woman!
 * In the Brother Cadfael mystery One Corpse Too Many, a wounded protagonist gives the "boy" nursing him a playful push in the chest and gets a shock. He also gets a clout on the ear.

Live-Action TV
"House: Why are you dressed like that? Why are you trying so hard to get my attention? Are you screwing with me? Cuddy: Are you screwing with me? House: That depends on your answer. (Cuddy says everyone knows that this is going somewhere, and that they're supposed to kiss now) (House says that they already did that and grabs her breast instead) House: Seemed like the logical next step. Cuddy: Really? I'm an idiot for being surprised."
 * Buffy the Vampire Slayer: Buffy turns invisible. Xander reaches out to find Buffy. His hands are at chest level. He quickly ascertains that Buffy's clothes are invisible too as he hurriedly explains to Anya.
 * In the House episode "Let Them Eat Cake", House begins to grope Cuddy in the middle of a serious conversation.

"Penny: Okay, now you're gonna help me get my arm into the sleeve. (Beat) Penny: Is that my arm? Sheldon: It doesn't feel like an arm. Penny: Then maybe you should let it go."
 * Fawlty Towers: Basil Fawlty once mistook a guest's breast for a light switch as he was trying to turn on the light from the other side of the door. His hand just happened to have paint on it as well, leaving a handprint on the guest's top for Sibyl to see moments later and draw the obvious conclusion.
 * A skit on an early '80s episode of Saturday Night Live had a character travel from the future just to squeeze one of the female player's breasts.
 * In The Drew Carey Show, Drew accidentally does this to Mimi. His reaction is screaming in horror and dousing his hand with alcohol.
 * In a cross-over between Live Action TV and Real Life, in the Lost episode "Live Together, Die Alone", When Jack, Kate, etc. are bound by the Others and searched for weapons, Alex accidentally gets some boob from Kate. It's in the bloopers section of Lostpedia.
 * The Big Bang Theory: Through a convoluted series of events, Sheldon has to help Penny get dressed, and she insists he close his eyes so as not to peek. The following dialogue ensues.

"Oscy: What did it feel like? Hermie: It felt like a boob. Oscy: Didn't it feel a little like an arm? Hermie: Why would it feel like an arm? Oscy: Because it was an arm."
 * Possibly a reference to the movie Summer of '42, in which Hermie and Oscy take two girls to the movies, and Hermie puts his arm around the girl, casually putting his hand on her boob, with a huge grin on his face. Afterwards, they have this conversation:

"Frank Costanza: He stopped short? That's my move!"
 * Seinfeld
 * In a memorable episode, Elaine trips and grabs Jerry's girlfriend's breast, confirming for him that, yes, they're real, and they're spectacular.
 * Don't forget when Kramer "stops short" with George's mom:


 * The Benny Hill Show. One of the most commonly used gags. Usually with a "honking horn" sound.
 * Neil Patrick Harris does this to Cobie Smulders in the Hilarious Outtakes for the Season 5 DVD of How I Met Your Mother. Funnily enough, this happens just mere seconds after Barney accepts Robin's invitation to play video games naked. Which can be seen here.
 * On Home Improvement, while driving his attractive female mechanic home, Tim makes a hard stop at a stoplight and reaches out to stop her from going forward, grabbing the wrong area in the process. When she asks why, he says that since he has three kids, it's basically a reflex. Unfortunately for him, the Detroit area just got cameras installed to take pictures whenever somebody goes through a red light.
 * A well-known Star Trek blooper has DeForest Kelley and Majel Barrett rocking back and forth holding onto each other while the ship's under attack. At one point he's holding her in the wrong place.
 * Along similar lines to the How I Met Your Mother example, Angie Harmon does this to Sasha Alexander in the Hilarious Outtakes for the Season 1 DVD of Rizzoli & Isles. The ladies were making fun of the show's blatant Les Yay subtext and when they finally broke down in laughter, more laughter followed when Angie accidentally grabbed Sasha's boob while reaching for a hug. Of course, this did nothing to cool the show's rampant Rizzles shippers. You can watch here.

Video Games

 * In Tales of the Abyss, this happened to Guy after Luke (under orders from Jade) kicked him into the girl's area of the spa (it should be noted that Guy is very gynophobic). The girls were angry at first, but then realize that he was the least likely guy to grope them and Anise asked him who was bigger: Natalia or Tear. After he said Tear, they got angry and called him a pervert again, netting him the new title "Naughty Devil".
 * Done for only fanservice purposes in an ending to Dead or Alive 4, since the girls are only there for fanservice anyway. Notice, though, that instead of merely slapping him, Lei-Fang probably killed the guy who did it. And then the other passengers applaud her for that.
 * He fell into water. By the genre expectations of both Dead or Alive, and of comedy (this was clearly a comedic scene), he's fine.
 * Yes, I'm sure they were applauding her for the kick.
 * This may be a bit of a stretch, but if you want to look into some Subtext, consider the first chapter of Fire Emblem: the Sacred Stones. Seth, a knight, grabs Eirika, the princess rather "brusquely" while they flee the castle.
 * Not that much of a stretch—he was grabbing her off the ground from behind while on horseback, so that's more than likely what he was apologizing for.
 * Rai on Arina in Rai (or was it Arina's?) ending in Waku Waku 7.

Web Comics
"Largo: (staring at the closed door) Something is there. I can feel it. Erika: There's nothing... Largo: (throws his hand back to shush her) SHHH!!! (Largo realizes "something", and looks back to see his hand right on Erika's chest) Largo: Wow. Those are a lot softer than I thought they'd be. [...] Yanagisawa: My God, what was that?? Piro: It kinda sounded like a truck running into the building."
 * Ethan did this to Lilah a lot in the early Ctrl+Alt+Del comics.
 * Francis does this to Jade in a PvP arc because he thinks he's in the future and that his actions have no consequences.
 * Megatokyo
 * Largo accidentally does this to Erika.


 * And Piro also accidentally does it to Kimiko in the Full MegaTokyo Panic omake.
 * While sharing a hoverbike in Sluggy Freelance, Zoe suggests Aylee hold on during their race. Being new to the female form, Aylee grabs what seem the most logical handholds.
 * Eerie Cuties had a moment when Melissa arranged this intentionally - to blackmail Ace with tears into a "make it up to her" date.
 * Dangerously Chloe had an unusual version. Chloe was impersonating Teddy via shapeshifting - and Succubus shapeshifting is rather limited. In her case the changes in upper torso necessary to look like a boy were not exactly minor - which is why she was already under strain keeping the shape. Enter her crazy classmate with a Voodoo Doll. So, of course, after Chloe fainted, the airbags spontaneously deployed - right when . With Unsound Effect "BLOOMP".
 * Happens to Buckaress in the League of Super Redundant Heroes strip seen here. The joke, of course, being that LaserPony is blind, the likely reason she didn’t knock his teeth out.
 * Bolter to Kokoro had it on the very first page: Guardsman stops Sister of Battle from moving out of cover, without looking. Well, she is looking where he put his hand (not that she could feel it in Powered Armor). Embarrassment (on her side), panic (on his side) and the rest of the comic ensue.

Web Original
"Victor: Burt just got farther with Riley than Angel ever did!"
 * Reed does this to Sarah by accident when he runs to greet her in a dark room in chapter 12 of LG 15 The Resistance.
 * Happens in College Humor's Awkward Rap.
 * We're Alive: Burt tries to put a shoulder holster on Riley but accidental cops a feels

Western Animation
"Starfire: Someone's claws are on my grebnaks! (suction cup noises) Beast Boy: My bad!"
 * In one episode of Teen Titans when the team had crashed into a pile in a darkened pit, the following dialogue occurs:

"Hawkgirl: Whose hand is that? The Flash: Sorry!"
 * Not exactly an example. Due to a quick look at the animation, you can see Beast Boy's octopus teeth on Starfire's butt (which is just as awkward).
 * Also in Justice League:

"Aelita: I... I'm invisible! Jérémie: (groping around for her in front of him) You're what...? Aelita: Hey! Jérémie: Oops... sorry."
 * In Code Lyoko episode "Vertigo", a bug in an anti-virus program turns Aelita invisible, and she runs to Jérémie:


 * In the second season of The Venture Brothers, one of Monarch's henchmen accidentally does to Dr. Girlfriend while sneaking her into the lair. This being The Venture Brothers, he freaks out and makes a bigger deal out of it than she does.
 * In one of the first episode of Teenage Mutant Ninja Turtles (1987 series), Michealangelo apparently does this to April O' Neil when he's untying the ropes that hold her to a chair. April O'Neil's expression when he's doing this really cements the scene.

Real Life

 * It's apparently a major problem in Japan, due to overcrowding on public transportation. Numerous amateur porn vids feature men intentionally fondling, groping, and outright molesting innocent women, and then attempting to play it off as an "accident". A study concluded that at least half of all the women in Tokyo have been victim to this phenomenon.
 * There were even references to that in a 1989 Charles Bronson film called Kinjite: Forbidden Subjects and is used as a culture dissonance moment when a Japanese man who's been transferred to his company's Los Angeles office is riding the bus.
 * These days there are women-only cars on trains for rush hours, which have considerably alleviated the problem. Of course now men are complaining about being stuffed like sardins in a can when women can enjoy relatively open, airy cars, due to the fact that men still form the majority of the workforce in Japan. Also, the attitudes have changed: when in the past women were expected to suffer in silence, nowadays gropers are extremely likely to get caught and sued. Aside from this, the punishment for it can now be as high as $1,000(US).
 * The accidents themselves are starting to be less likely—in large part because women have realized that it's quite possible to, even in the most crowded cars, avoid this happening by accident...which in turn makes it harder to do it on purpose and pretend otherwise. It's quite possibly not as much worry about perverts, though, as much as the simple fact that it's rather embarrassing to (nearly) accidentally inflict Marshmallow Hell on somebody.
 * The game "Ninja", played co-ed, can sometimes result in this. For amusing results, get some teenage, Adorkable guys to play with cute girls. This trope will happen, it will be fully accidental, and if you really want to see a guy blush, this is about as good a setup as you can get.
