Nudity is one of the last great taboos, particularly in the United States. Whereas it's OK to show violence, blood, and to a certain extent hate speech on TV, a tiny bit of nudity will cause an outright scandal. Just ask Janet Jackson and her "nip slip", which got more attention than the show she was putting on at the time, despite its sexually suggestive content that some say bordered on sexual assault by her co-star.
So while nudity itself is right out, the insinuation of nudity, as well as the reaction to it, is just titillating* *snicker* enough to make it onto the air, especially on comedies.
Naked people are funny, after all, especially paired with a prudish costar to react to them, or in a situation where they're not expected or wanted.
A character who ends up naked in a place they don't expect may need to use Hand or Object Underwear or a Scenery Censor to hide — from the camera, that is — after losing their Modesty Towel (and they will lose their Modesty Towel). Almost always they'll end up being seen by another character, meanwhile, the audience will have to make do with, at best, a Toplessness from the Back shot.
The Invisible Main Character probably can't wear clothes, if only because the insinuation that he or she is running around naked makes it funnier — plus, when the character does inevitably materialize, it'll invariably be in front of as many people as possible.
The Innocent Fanservice Girl won't understand why everyone's freaking out, while the Shameless Fanservice Girl won't care. Ms. Fanservice and The Vamp will understand, but... that's probably the idea.
It's tempting to suppose that nudity is funny precisely because it's so unusual in the "civilized" world, and weird things are naturally funny. However, this logic goes out the window when you learn that nudity has been a prominent ingredient in humor for at least 3,000 years. Even the ancient Egyptians found naked people funny, and they weren't themselves shy about baring their arms or legs, or even their chests. So maybe the humor lies primarily with boobs and penises, which have been shameful to expose since Neolithic times.
Special mention goes to nudism. Nudism is a philosophy that basically boils down to "There's nothing wrong with being naked in certain situations, including some group situations". The Theme Park Version of this is "Hey, look, naked people," and is a great way to throw some Fanservice into your show. Nudists tend to be shoehorned into a few specific roles, depending on their role in the plot:
If a character is introduced as a nudist, that character will be either extremely young and attractive or extremely old and ugly, depending on whether the character is being played up for Fanservice or comedy, with few exceptions. Middle-age and underage nudists do not exist (although the latter have some very obvious reasons for their omission). Has a touch of realism in it — real nudist organizations often have a pattern of children dropping out as they enter adolescence, then returning in middle age after they become comfortable with their bodies again.
As a general rule, any nudists will be new age hippies, or if they're old, actual original hippies. Talk about mantras, releasing the inner calm, etc., is common.
Depending on age, nudist characters are either airheads or old Zen masters — the younger you are, the stupider you get.
Said nudists will either be extremely puritanical, and often militant about their nudity (so called "Right to Nude" activists demanding the right to go naked on a local beach, for example) or extremely perverse (in which case they are really "swingers"). Almost universally, they will refuse to acknowledge (or genuinely not recognize) that they are making other people uncomfortable with their nudity, nor will they ever get uncomfortable themselves. (This one has a surprising amount of truth to it.)
Revelation of said nudism will cause, on average, one character to react angrily and one other to reveal that they have always been interested in nudism, were really raised as a nudist, or experienced something similar in their past. For example, sunbathing on the beaches during a European trip. These will almost invariably be an upset man and an open-minded woman, or an extremely interested man and an extremely offended woman. If there's any sexual tension between the two, it'll almost definitely be that couple.
If there is a third person, it will likely be the perverted friend who completely misses the point and spends the entire episode trying to sneak peeks or take photos. If there is an older cast member, he or she will probably already be naked when everyone else arrives.
If a male or female character decides to go to a nudist beach or resort to look at women or men, said women or men will either not exist or be extremely old.
If a character disrobes at a beach and neither a sign clearly saying "Nude Beach" nor other nude people are visible, it will turn out that it is not, in fact, a nude beach. The character either went to the wrong beach, was misinformed (maybe it used to be a nude beach), or just assumed it was a nude beach (most likely because they're tourists who think all the beaches in whatever country they're in are clothing-optional, or because they're from a country where (in the writers' imaginations) all the beaches are clothing optional). Although, again, some Truth in Television to this, as the United States is almost uniquenote The only other similar country is China. without even a single legally protected clothing optional beach. Every Nude Beach in the U.S. is instead politely ignored by the local authorities, and not actually legally protected.
Put to use as a prank in an ad for Time Foto: "We blow up your favorite holiday picture."
An advert for British opticians Specsavers shows a confused man in the hotel spa with fogged-up glasses trying to navigate through the steam. He passes through a door into a steamy hot fug. Believing he has found the sauna he drops his towel and hops onto a bench. The steam clears. We see he is in the hotel kitchen. Several dismayed chefs look back at him. Worse still, the head chef is Gordon Ramsay, who comes in close and scowls menacingly.
When the Honda Pilot SUV crossover was introduced, Honda ran an ad depicting its driver coming across a hot air balloon that's landed in the middle of the road. The man offers to take the entire crew with him to wherever they're going. "There's one thing. We're nudists." As he's backing up, he checks the mirror, flinches, and looks out the dash-mounted rear window camera instead.
A running gag in Maicchingu Machiko Sensei is that Machiko ends up naked in every episode. No exceptions, and the universe often takes extreme measures to strip her, such as having a box fall in just a way to catch the corner of her dress. Of course, one of her students also loves to intentionally strip her, expose her panties for her by flipping up her dress, and occasionally outright grope her (as a way of saying hello). All of these are played as a Running Gag. The title word, Maicchingu, refers to the pose she makes after losing her clothing, and it's played up for as much Fanservice as possible (for a early 1980s TV series). It's such a part of the series that they included it in the opening title sequence. The big catch? Maicchingu Machiko Sensei is a kids show, she's an elementary school teacher, and so her students are all around 8 years old. Oh, and it played on Japanese TV, rather completely subverts Barbie Doll Anatomy, and was aimed squarely at kids the age of Machiko's class.
The lesser known clean manga, Nippon no Razoku (Literal translation: Japanese Naked Tribe; figurative translation: Japanese Nudists) involves a group of nudists who attempt to take over Japan, or... something. One of the main characters, a young tomboy is relatively normal, except for her relative lack of a nudity taboo, as well as the fact that once she disrobes, she gains superpowers.
This manga takes the trope at face value and subverts it at the same time: The leader of the nudists acts like a pro wrestler instead of being ancient — but is still an idiot, the fat guy joins up with the nudists in the hope of forcing the women in town to strip, and one of the female characters (not the young one) is perfectly aware that she's giving everyone a free peep show, but can't bring herself to disobey her father and get dressed.
One episode had a scene parodying the nudist colony moment in A Shot in the Dark (see film examples below). The Clouseau and Cato characters wore only fig leaves.
And a later episode had the Lupin gang forced to make an emergency helicopter landing at a nudist colony. Goemon protested, needless to say.
Played straight and deconstructed in Invisible Girl Ea, a Japanese video-game storyline turned live-action TV miniseries. Ea's compulsive invisibility prohibit her from wearing clothing, as her skin being touched causes her invisibility to turn into a Predator-style CGI effect. The comedy comes when the main male lead has to make excuses and generally freaks out when Ea's powers turn off, usually at the worst possible times. The deconstruction comes when the main male lead and Ea realize that she's never going to be able to live a normal life, as she can't wear clothing, turns invisible and visible at more or less random, and has to hide from any number of random government and corporate interests who would love to dissect her and figure her powers out. Finding a way to remove her powers is the major plotline of the series.
In Chapter 52 of The Wallflower (which was translated to Perfect Girl Evolution in the United States), Sunako is possessed by a cursed diamond pendant. The diamond is essentially an exhibitionist — it wants to force her to dress up and attract attention (but mostly of the good "Wow, she's beautiful" kind). While under the influence of the diamond, she sleepwalks naked to one of her male roommate's beds, and wakes up on top of him. In Chapter 53, she has a mild breakdown because of it, and forces herself to believe that she was dressed in... something during the event. This starts to affect her in other ways — namely, after taking a shower she blanks out and thinks she's put clothes on when she really hasn't. Her four male roommates rather quickly start begging her to Please Put Some Clothes On, while the guy into whose bed she sleepwalked has to chase her to school and back making sure she doesn't accidentally strip naked.
This starts off with her putting on only an apron to cook breakfast that morning, to attempting to go to school naked (Kyohei forces her to put on her school uniform's optional dress part (designed to be worn with a uniform under it), to casually stripping said flimsy dress off in front of some pornographers who scouted her when she was in a daze. It's only after the pornographers bring in the male model to have sex with her that she snaps out of her delusion.
Yoruichi from Bleach is completely nude when she changes into a human, which she is not bothered by - to the point where she can use this to irritate Ichigo.
Naruto's Sexy No Jutsu is another example, though the main bits are covered in clouds of smoke. Severe nosebleeds abound when Naruto uses this technique, except for Jiraiya, of course.
And in the Noto-sama games, Noto and Yamato do their best to strip whomever they come across...
Need we mention the elephant dance of Shin Chan fame? And sometimes he's still wearing pants doing this...
In One Piece, Franky spends nearly an entire episode without any pants, after his were stolen to bait him.
Mahou Sensei Negima! had a Running Gag during the Tournament Arc involving Takane D. Goodman, who ends up getting stripped naked pretty much every time she appears. It gets to the point that in one of her later appearances, the joke is that she isn't naked. Even the other characters (who, being denizens of the Negiverse are quite used to Clothing Damage happening to just about everyone on a regular basis) start referring to her as a stripper.
Really, a good chunk of the nudity in the series is this. There may be a lot of Fanservice, but it's played for comedy quite often.
Comes to a head in the latest Crowning Moment of Funny when the heroes accidentally find out how Evangeline spends her free time: playing video games in the nude.
Doraemon has Shizuka, the main character's love interest. A Running Gag that's been going on for 25 years now is that any time she takes a bath — anywhere, anywhen — Nobita will walk in on her, run past her being chased by a dinosaur, teleport her into the middle of school, accidentally brainwash her to become a militant nudist, etc etc.
Ranma ½ has several episodes using this with Ranma changing from male to female and back again in places like the public baths.
In Fairy Tail, we have Grey Fullbuster, Reitei Lyon, and their teacher Ur. While technically they don't get completely naked in frame, it's heavily implied that the three spent the majority of their training that way.
When Grey first meets Lucy, he's already in his boxers, which mysteriously disappear... and he asks Lucy for her panties...
Accidentally stripping seems to be limited to Gray though; Ur was horrified when it became habit for him and he started doing it in public.
It looked like Lyon picked it up in the Nirvana arc.
Also from a manga of Hiro Mashima's, Julius of Rave Master. At first he was just a pretty boy. Once he became a good guy he took his narcissism to the next level by insisting that not only should everyone be able to see his beautiful face, but also his beautiful... everything. His explanation for why he'd strip usually didn't include the actual reason for why he stripped.
The one of the many charms of Angel Blade, is how dramatic and serious characters can be, even with all their naughty bits on display. It's even funnier whenever the main character actually becomes aware of it.
Hamaya from the manga Girl Got Game has on three occasions suddenly appeared in front of his friend, stripped down to his birthday suit. Two times were because one thing or another tore all his clothes off; the second time he had just eaten halluciongenic mushrooms when he took his clothes off.
In Hayate the Combat Butler, before the seriousness of the Athens arc takes over it's averted. The group goes to a nudist beach. The girls understandably wear bikinis (and those three girls try to seduce Hayate, while there); A game of beach volleyball is played, with the participating female being told she needs to be wearing a bikini by the rules; and not one character is ever implied to attempt to be nude and there are no background characters ever. You would almost think it was a mistranslation of some sort, except that it's referenced several times as a Nude Beach.
Kore wa Zombie desu ka? (the anime version) first demonstrates Ayumu's zombie durability by getting hit by a truck, which for some reason causes all his clothes to fly off (terrifying the nearby schoolgirls).
After losing most of her powers, Haruna's Masou Shoujo clothes have a tendency to suddenly disappear.
People lose their clothes quite a bit in Kochikame, especially main character Ryotsu.
The (in)famous "toothpick scene"note For the two of you who never seen it, Shinji is in the bathroom, naked, gets startled when seeing Pen-Pen there, and runs off to Misato and ask WTH is going on, meanwhile his "things" are conveniently blocked by a can of beer on the table, Misato picks it up, only for Shinji to continue being censored by a substantially smaller toothpick-holder (it was behind the beer can) instead. in Neon Genesis Evangelion. Repeated with Asuka in Rebuild 2.0.
In Ichiban Ushiro No Daimaou Keena Soga has the ability to disappear not only visually, but from any magical tracking means. However, any clothes she has remains visible so she is always stripping naked (with the hair ornament she never takes off as the floating around as the only clue that she's even in the room). In episode two, she is running away from a dog when she runs straight into Akuto Sai and ends up becoming visible again completely naked and riding on top of him. There is also Junko Hattori who got her clothes blown off from fighting Akuto in a class full of their classmates.
There is Keita from Inukami! who always ends up naked in public whenever he pisses off his familiar, Youko. Youko teleports him out of his clothes in to the most populated place nearby that the cops are already familiar with him and the local perverts who are always in jail think of him as one of their own.
Toori of Kyoukai Senjou no Horizon spends an inordinate amount of screen-time naked except for his portable, always-present magic censor. This is because his matron god is Ame no Uzume, Japanese god of merry-making, whose part in getting Amaterasu to leave her cave...was stripping naked and telling jokes.
Marvel's She-Hulk always seems to end up naked one way or another. Like the time her Skrull girlfriend partner tried teleporting her to their ship, but only teleporting her clothes, leaving She-Hulk naked in the middle of a crowd.
During Peter David's run on Incredible Hulk, the Leader shoots the Hulk with a BFG, seriously injuring him and incinerating his clothes. The Hulk regenerates almost immediately, but his clothes don't. The Leader requests, (more or less) "Dr. Banner, please! There are ladies present... And you're making some of us men feel inadequate."
Marvel's Susan Storm-Richards, AKA: The Invisible Woman of the Fantastic Four, has sometimes been a victim of unwanted public nudity, usually just narrowly avoiding complete and utter humiliation by turning invisible.
In Catwoman When In Rome, DC anti-heroine Selina Kyle is forced to jump out the window completely naked when her hotel room is bombed and survives by landing in the pool in broad daylight, with the Riddler and Italian hitman known as the Blonde landing in the pool with her. The naked and very wet Selina manages to stay in control despite her sexual humiliation being played for laughs.
In the German comic Werner: Meister Röhrich, after the one or other explosion
For an example of a hero taking a Shameful Strip to extremes to save innocent people from a crazy terrorist, DC's Firestorm did this to the villainess Plastique in which he used his power to deatomize her clothes so he could get the bombs that were attached to her and dispose of them safely somewhere else - leaving the beautiful red haired villainess completely naked and sexually humiliated in public, causing men and women alike to laugh at her. While undeniably cruel, it should also be pointed out that otherwise she would have blown up a lot of innocent people. See Shameful Strip and Naked People Trapped Outside.
Avengers Assemble #9-11 involves a bet between Tony Stark and Bruce Banner as to who can be the first to successfully rescue a missing scientist. The loser has to walk naked from Avengers Tower to the Baxter Building and back (in downtown Manhattan). In the end, they BOTH lose and end up taking the walk of shame together, Banner in his Hulk form, no less. Even better, Tony's effort to jam all electronics to prevent anyone taking pictures is defeated when Spider-Man shows up to take a picture with an old-fashioned flash camera that ends up on the front page of the Daily Bugle under the headline "Naked Justice."
Areola from Not Another Teen Movie is a foreign exchange student from "Europe" (in a deleted scene, she dodges the question of what country she's really from) who spends the entire film nude, with no one really reacting to her, except the main female character looking uncomfortable the first time she's introduced. Later, during a party, another nude girl sees her and screams out "Oh my god! She totally copied my outfit!". When speaking, her English-but-heavily-accented (with random accents) voice is subtitled, with the subtitles moving out of the way to make sure they do not block her breasts in any way.
Confetti was a movie about three couples preparing for their weddings. One of the couples is a naturist couple, who are preparing a nude wedding. Both the actress and actor complained loudly after the movie hit theatres, claiming they were deceived about the amount of nudity required and how much would be left in the final film.
Carry On Camping, an old Carry On film, had two hornballs trying to trick their wives into going to a nudist campground. They screwed up, however, and drove to the other campground with the same name. Then Barbara Windsor's top flies off.
Euro Trip involved a nude beach scene. In it, the main male characters try to visit a nude beach to check out naked European women, only to discover it's full of naked men who had the same idea. When the main girl character takes her shirt off to tan in her bikini, they're chased down the beach by hordes of naked men desperate to see a nude girl. Later in the film, the girl who is the main character's love interest strips down and has sex with him in a confession booth, and her buttocks are squashed into a vent and seen through glass for comic effect.
A Shot in the Dark, the second Pink Panther movie, involved Inspector Clouseau having to sneak onto a nude resort to find a witness. They end up having to escape for some reason or other, and end up arrested for their trouble.
The audience is "treated" to Jason Segel's full-frontal privates at the outset Forgetting Sarah Marshall ... the shock value of the penis had the audiences howling.
By extension (har har), anything even tangentially related to Judd Apatow is likely going to involve giving the audience a peek at some guy's schlong. Suffice to say that Apatow has a firm grip on this trope.
The titular character in Monty Python's Life of Brian makes an accidental naked appearance in front of a crowd that thinks he's the Messiah.
Something of a subversion: One Monty Python's Flying Circus episode featured a recurring BBC announcement that one channel was showing a debate on censorship between the Bishop of Bristol and a nude man. At one point, the debate is shown, where the nude man argues vehemently that such filth shouldn't be shown on television.
Another sketch had a cricket game being held in a nudist colony; Complete with a fully clothed "Streaker" being marched off the field by a nude police officer holding his helmet over the streaker's trouser fronts.
They continued to do so with their post-Python work as well, including John Cleese's nude scene in A Fish Called Wanda. Terry Jones also (allegedly) wrote the Novelization of Douglas Adams' Starship Titanic in the nude, and only agreed to writing it if he could do so; he also apparently played the organ while nude in Monty Python's Complete Waste Of Time to taunt players for breaking the rules.
In the first one, there is a scene where a maid enters Irene Adler's hotel room, and gasps upon seeing Holmes cuffed to the bed with a pillow covering his groin (this supplies the page image for this trope):
Sherlock Holmes: Madam, I need you to remain calm, and trust me, I'm a professional. But beneath this pillow... lies the key to my release. [The maid screams again and runs out in disgust; cut to Holmes retelling the story to Clarkie in a carriage] Of course, she misinterpreted my meaning entirely.
Constable Clark: Naturally, sir.
Sherlock Holmes: That's why I find this modern religious fervor so troubling. There's no room for misunderstanding.
Constable Clark: Faith runs right over reason, sir.
Sherlock Holmes: Indeed. And chamber maids were once such a liberal breed.
Constable Clark: My wife's a chamber maid, sir. [pause] Anyhow, it's a good thing she was offended, sir. Otherwise we'd never have found you. The Inspector's been over to Baker Street himself twice this morning, sir.
Sherlock Holmes: Ah, yes. [another pause]
Constable Clark: Just joking about the wife, sir.
In the second film, we find that Mycroft apparently has a habit of wandering around his home stark naked. He has a cheerful conversation with a mortified Mary when she runs into him like this, while his servants, who obviously are accustomed to this, don't even bat an eye when they come in to serve breakfast.
The 1980s B-movie The Invisible Kid featured an invisibility potion that didn't affect clothes and only worked for a little while. When the effect wore off, the character(s) usually materialized au naturel in an inconvenient place.
This is extremely common in fiction using Invisibility, especially if it's a teen+ comedy or the subject is female. Indeed, the invisible woman fan subculture on the Internet calls this a "TFI" — True Femmes Invisible. Contrast "FFI" - Fading Femmes Invisible — which is what you call it when clothing goes invisible, too.
Which means we should bring up the Fantastic Four movies. Although in Rise of the Silver Surfer, it's because Sue's powers have switched with her brother Johnny's, and her clothes were instead burned off.
Then there's also a scene in Rush Hour where he and Chris Tucker don't reach the same nakedness level while fighting their rivals in a bath house, but end up thrown out butt naked.
In Ali G In Da House, Ali has cuffed both his hands to the railing of his local city hall to protest the closing of his favorite community center. The rival gang takes the opportunity to come by and pull down his pants, as he can't do a damn thing about it.
Very much subverted thrice in A Clockwork Orange (two of them in the first 20 minutes). And played straight in a sped-up montage of a menage a trois.
This happens in Kindergarten Cop, where the protagonist (Arnold Schwarzenegger's character) walks in on his partner having sex with her fiancé; the whole scene is played for laughs, especially when the guy covers himself using her very feminine bathrobe. (The guy later reappears at the end of the film, where Schwarzenegger jokes that he didn't recognize him with his clothes on.)
In Knightriders Julie (Patricia Tallman) becomes a victim of Naked People Trapped Outside when she is seen naked after having sex with Alan in the forest at night. When she realizes she's being seen by the group's Friar Tuck, she has a very subdued almost too stunned to react Naked Freakout as her shame is played for laughs.
The bath scene in Disney's Mulan. Beginning with Mulan nearly getting caught out by three fellow soldiers, continuing with Mulan being completely freaked out by the three ugly naked men in far too close proximity and then the over-the-top payoff when, upon lamenting she never wants to see another naked man again, the ENTIRE ARMY stampedes nude into the river.
The Rugrats Movie: The scene where Dil pulls down Tommy's diaper showing his behind. His diaper usually slips down while he talks to his friends.
Rugrats in Paris: In the end, where Angelica rips Coco LaBouche's dress to expose her underpants.
In a combination of both this and Fanservice, The Proposal has the scene where Sandra Bullock takes a bath, but the towel is in the adjacent bedroom - with an angry dog! And to make things worse, after removing the dog from her way (with arms strategically positioned), she collides with an equally naked Ryan Reynolds.
Mr Chow in The Hangover, or as he's more commonly known: "the naked Asian dude."
In the Borat movie, Borat gets in a fight with his manager while both are naked in their hotel room. They end up running down the halls, riding the elevator, and running into a business convention, all while naked.
Subverted in Silverado: characters react with horror to the sight of Paden (Kevin Kline), who has been robbed of everything except his long johns. Although his body is completely covered from neck to ankles, parents still pull their children away and one character tells him to "put some clothes on".
In 1984's Electric Dreams, downstairs hottie Madeline walks in on Adorkable Miles just as he has left the shower; Miles desperately tries to cover both himself and his sentient computer Edgar, who has a crush on Madeline and wants to meet her.
I Love Trouble features Julia Roberts skinny dipping and then getting her humorous punishment for it by getting photographed by a bunch of boyscouts.
X-Men Origins: Wolverine uses the trope. After Wolverine's initial rampage in the buff, which is naturally done seriously, he ends up running to the nearest barn, to the surprise of the old couple who own it.
In The Maiden Heist, George is obsessed with a nude male statue called "The Bronze Warrior", and strips completely naked in order to fully appreciate the piece-and compare the statue's physique to his own. Hilarity Ensues when George is in the middle of admiring the statue naked, when a guard comes 12 minutes ahead of schedule. George ends up hiding in a crate, still naked. Major Fan Disservice, unless you have always wanted to see William H Macy's bare backside.
The Bowler: Maybe you should put some shorts on or something, if you want to keep fighting evil today.
We Were Soldiers, suprisingly enough. There is a deleted scene where a soldier tells a story about a previous unit he was in, where their platoon commander, fresh out of ROTC, ordered all of his soldiers to put on all of their decorations so he could see what kind of men he was leading. He particularly gets in the face of the big ugly scarred platoon Sergeant. The sergeant returns to the barracks, and comes back wearing only his combat boots, with his decorations pinned directly to his chest, and wearing a Medal of Honor. The lieutenant, seeing the medal, is forced to salute the platoon sergeant.
The fantasy rom com Splash introduced Madison in human form walking near the Statue of Liberty area naked.
Plenty O'Toole's Naked Freak-Out while being forced out of James Bond's apartment wearing nothing but her panties and high heels in Diamonds Are Forever was clearly played for laughs.
Though he's not really a nudist, per se, when Zedd shows up in Wizard's First Rule, he's on his Wizard's Rock stark naked; Kahlan reacts with shock, and Richard makes it clear this is a normal thing for him. He later suggests to a sorceress that she try it some time, though this is less about comedy and more about Zedd being a horny old man.
Werewolf Sergeant Angua of the Watch often goes "plainclothes" in the course of the investigation, and when she needs the use of hands or a non-wolf mind, she usually doesn't have her clothes on hand. While usually alone or with a fellow officer who's polite enough to close his eyes while she's naked, twice in Jingo she's forced into a situation where she appears naked in front of strangers. Both times, she tells off the gawker while turning nearby curtains or a tent into makeshift clothing.
Similarly, female vampires are unable to do that whole "turn into a swarm of bats then re-form in full clothing" thing that male vampires are able to do, for some reason. Sally, the Watch's first vampire, and Angua end up having to steal clothes from a strip club in Thud!! when they both end up naked during an investigation. As both have issues with each other, Terry Pratchett uses the scene to subvert various tropes - they are the classic ill-matched pair of patrol partners, as werewolves and vampires normally do not get on. Sally has been flirting with Angua's man, and wolves are territorial. finally Sally defuses the fight by noting that they are both naked and about to do something extreme while knee-deep in mud; people would pay good money to see that. This perhaps Pratchett's Shout-Out and author comment on all those slash Fan Fictions in which his characters get it on together, in unlikely homo pairings, in contrived situations.
While not actual nudity, but in one illustration in The Last Hero Rincewind is strapped into a three-axis rotation device, stripped down to a loincloth for no clear reason other than this.
The clear reason other than this is that it's a parody of Da Vinci's Vitruvian Man (oh, come on, you've seen it, it's the "guy with multiple arms and legs in a circle" picture). The loincloth is a sop to modesty, VM is fully nude.
In Codex Alera, when Invidia Aquitaine is supremely Out-Gambitted by Amara, the latter leaves the former tied up naked in a forest, because: "The poisonous bitch deserved it." And she really does.
In Martin the Warrior, the Big Bad Badrang cuts a random minion's belt when he finds himself needing a rope. The belt was holding up the kilt which was the only thing said minion was wearing, and he ends up with his fellow soldiers and the whole slave line laughing at him. Since they have fur, this may not be as big a deal as usual.
In The Trouble With Moonlight by Donna MacMeans, the heroine, Lusinda Havershaw, is a beautiful virgin who can turn invisible when she absorbs enough moonlight, but her clothes do not turn invisible with her, so in order to work as a spy and retriever of lost trinkets she must be completely naked. If she is away from the moonlight for too long, she will gradually become visible again. Three times in the book she becomes trapped in a house on a mission and away from moonlight and she is forced to make a hasty escape before she materializes, so as to avoid capture and humiliation. In both instances, she is witnessed in her half-visible state and assumed to be a ghost, at one point described as "a ghost with a shapely backside".
Wedge Antilles' "greatest revenge" on Wes, who'd been pranking him for months, involved tricking Wes into a situation where he was naked, smeared in fruit-and-leaf-compost, forced to grab the Ewok doll he'd been pranking Wedge with to hide behind, and seen by the entire squadron. And it was awesome.
Wes: I have so been set up.
Another character tells the story of the time they wound up locked out of their quarters and were discovered in this state by their (previous) commanding officer, widely believed to have No Sense of Humor. Seeking Refuge in Audacity, the character saluted the CO and reported an unsuccessful test of the Personal Cloaking Device.
Face: He turned out to be all right. He made me hold salute for a while, looked me over, returned my salute, and said, "It's obvious this project was a failure. I suggest you go and cover up its shortcomings." So I did.
Live Action TV
There is actually a show from the Ukraine called "Naked and Funny", which is a hidden camera show in the style of Candid Camera, but often featuring public nudity played for laughs. It's also one of the many reasons to love Europe.
Baywatch did this once, with the requisite random Baywatch girl who suddenly remembered she was really interested in this kind of stuff, even defending their rights against another, suitably offended Baywatch girl. Also had the crazy old naked man subtype, as well.
Caroline In The City had a scene when Caroline decided to allow her nude body to be seen by her fiancé for the first time. Unable to bear the embarrassment, she covered her eyes, disrobed and walked out to her fiancé and two friends, who had just arrived.
At the end of the episode, the two friends try to return the favour.
The Kids in the Hall: The heart of a few skits, like one where an employee at a meeting won't stop giggling while going over his report, leading to the revelation that he wrote the whole thing while naked, much to the disgust of everyone else there.
Monk had a nudist episode, aptly named "Mr. Monk and the Naked Man," wherein Monk had a meltdown about there being naked people on the beach, trying to accuse the nudist he met of being the villain, despite his airtight alibi. Said nudist was a new-age hippie, of course. Monk's fear of nudists turns out to come from a memory he had when he was young in which he was seen naked and then being hit by someone and being held upside down. He gets over it when he realizes he was just remembering his birth. On the subject of a Noodle Incident, Natalie mentions having been on nude beaches in Europe when she was in college.
A great case when Monk uses this without problems is in "Mr. Monk and the Red-Headed Stranger": he proves Ms. Mass is lying about being blind by bailing out a known streaker who has interrupted TWO police press conferences and sets up a meeting with her in the park where he would usually run and watching her reaction. Her own laughter and notice of the streaker gave her away.
Likewise, the Baywatch parody Son Of The Beach had a nudist episode. Slightly memorable because the European male-bimbo character's censor-bar for his... bits... was hilariously large, and that of the main character was nearly nonexistent.
Mentioned in several episodes of Star Trek: The Next Generation. In an episode where Counselor Troi was (briefly) engaged to be married, we learn that Betazoid weddings are traditionally held in the nude. Their culture believes that it symbolizes love. Betazoids, being telepaths, are a very open people.
In another episode, Lwaxana Troi shows up to her own wedding naked, after getting tired of her fiancé and his advisors' cultural insensitivity towards her.
Data's "mother" (Soong's wife) mentions that Data originally had no concept of modesty, and thus wouldn't wear clothing because he didn't see the need to. Naturally, an anatomically correct android in the buff was a problem. His shipmates thought it was pretty funny.
When Q was stripped of his powers and kicked out of the Q Continuum in the third season, he makes his first appearance in the episode naked.
The start of Star Trek: Nemesis features the Enterprise crew going to Riker and Troi's wedding, which leads Worf to get embarrassed and Picard to hit the gym.
On Star Trek: Enterprise, when Hoshi tries to sneak into Reed's quarters via the ventilation shafts (for entirely legitimate reasons), her shirt snags on something as she falls. We get a shot of her topless and covering her breasts with her arms. Her line when Reed sees her:
Hoshi: Whatever you were going to say, I don't want to hear it. Just get me a shirt.
In an episode of Seinfeld, Jerry has a girlfriend who was not that concerned with wearing clothes when there was no one around to see her except her boyfriend, with whom he discovers that there is "good naked" (walking, for example) and "bad naked" (coughing). She didn't react especially well to Jerry deciding to take the same approach - she apparently felt that all male nudity was "bad naked."
In another episode, Jerry was on a subway car across the aisle from a fat man and he fell asleep. When he woke up, everyone else on the train had gotten as far away from the fat man as possible, because he was now naked.
MAN: I'm not ashamed of my body.
JERRY: See, that's your problem. You should be.
In the first episode of Malcolm in the Middle, Malcolm's parents, Hal and Lois, wander around the house naked for various reasons, oblivious to the discomfort this causes their sons and anyone who drops in.
The League of Gentlemen: Nude Day. The fact that what you're seeing is a man in a naked woman costume is one of the more alarming things on the entire show, and that's saying something.
Wings had an episode where the main character and his wife, upon having finally gotten their last roommate to move out, decided to get naked inside the house. They like it to the point that they're naked most of the episode, and talking about visiting a nude beach. The rest of the episode was one Scenery Censor gag after another, until their neighbors' perverted kid managed to get blackmail photos of them... cleaning the rain gutters in the nude. Huh.
In Friends there's the 'Ugly Naked Guy'. This is an interesting example as he is almost never actually seen* In the season 5 episode "The One Where Everybody Finds Out" we finally get to see him in the flesh, although only from behind but only described by whichever friend is spying on him at that moment.
Poked fun at in a flashback episode, where the girls mourn the fact that "Cute Naked Guy is really putting on a lot of weight".

In the "Spin Cycle" episode, Lacey learns that the women of Dog River have a nude calendar every few years or so and she is tasked to find people to sign up. Karen and Wanda are about to strip wherever they were and Lacey stops them each time. Turns out Emma thought Lacey wouldn't bother with being in the calendar so Lacey goes to her and the photographer and strips naked. Then it turns out that the photographer was just a customer of the diner.
The first episode of Rome had Atia nonchalantly walking around completely nude in front of her son, to help establish the different social attitudes of ancient Rome. Cough.
The Jonathan Creek episode "Mother Redcap" has Maddie dropping around to the home of a nudist real estate agent who was helping her with a mystery and ending up having tea with him and his nudist friends to her obvious discomfort. (He had actually told her he was a nudist before this occurred, but she hadn't been listening.)
Firefly: The episode "Trash" is a How We Got Here bookended with naked Mal, stranded in a desert. "Yep...that went well..."
This shows the personality differences between the female characters very well. Inara (who has seen plenty of naked men) simply tells him he is naked; Zoe pretends it isn't happening and calls him Sir with usual military demeanour; Kaylee grins from ear to ear; River (too young) is conveniently absent (she probably would have made an inappropriate and frank comment on his anatomy).
Used on M*A*S*H, almost always involving the showers, often entailing stealing someone's clothing, usually including Radar, and occasionally presenting actual danger in the form of snipers or homicidal patients.
Not to mention the episode where Hawkeye goes to dinner in the mess hall wearing nothing but his boots, just to see if he could get a rise from the other war-weary members of the camp.
In one memorable episode, after Hawkeye has fallen victim to one too many of BJ's pranks, he convinces Winchester, also a victim of BJ's joking, to aid him in stripping BJ of his clothes while sleeping, nailing his blanket and pillows to his cot so that he can't use them as cover, and then relocating him to the nurse's tent. Then they make the P.A. announcer call for all surgeons to report to the E.R., forcing a naked BJ to run out naked in front of the whole camp.
As above, the first the audience sees of Zedd in Legend of the Seeker is the old wizard naked talking to the clouds. Well, talking to a rooster about the clouds, anyway. Which is to say that Kahlan catches him naked, and holding his c--
In an "On the next episode" gag of Arrested Development, Tobias, a former Never-nude, overcompensates when briefly cured. He walks down to the family breakfast naked.
In the How I Met Your Mother episode "The Naked Man" the gang learns of and uses the titular seduction technique:
Step 1: Wait until your date leaves the room.
Step 2: Strip naked.
Step 3: When your date comes back in, they're so impressed by your bravado that they have sex with you.
* Works two out of three times*
The "inventor" says that it's a "Hail Mary" play. As in, the date's not going so good, you know there won't be a second one, so you may as well give it a try since you've got nothing to lose.
In one episode of Buffy the Vampire Slayer, the Slayer gets turned into a rat. When she's turned back to human, she is (obviously) naked but retains her modesty with some conveniently placed furniture.
Luckily for her, this happens in the presence of Oz, who is cool about it, because Oz ends up naked all the time anyway. Commented upon in various DVD commentaries

In an episode of the 80s detective show Simon And Simon, Rick and A.J. go undercover at a nudist resort. Standard hijinks for this trope ensue, with A.J. considerably more at ease than his brother. At one point they end up at a dinner party only to find everyone dressed but themselves. Apparently it was resort practice to always dress for dinner. Even A.J. is cowed, and after donning their Hand or Object Underwear, they beat a hasty retreat.
There was one episode of Stargate SG-1 where Daniel Jackson came back from the dead naked. (It's implied that it's some sort of Ancient practical joke that Oma was playing on him.) He wound up landing in Jack's office while the General was trying to have a briefing with the rest of SG-1 (Sam and Teal'c, at the time). It was awkward.
The other time he came back from the dead naked (yes, this happens to him more than once) was played less humorously... except when we find out that his nickname translates to "The Naked One."
In "Gridlock", as the Doctor tries to track down the carjackers who took Martha, one of the couples occupying the cars he climbs through is a pair of nudists. He doesn't hang around long enough to bother giving them an alibi.
How about Donna Noble and the Meta-Crisis Doctor's first conversation, after he's just grown out of the spare hand on the TARDIS:
Donna: It's YOU!
Doctor Double (emphatically): Oh yes!
Donna (glancing down, then pointedly to the left) ....You're NAKED!
Doctor Double (just as emphatically): Oh yes!
Also done in the series six premiere, when an Elizabethan-era nobleman barges into his wife's bedroom demanding she tell him where "that doctor" is. She insists that she's alone, but when an inconveniently-timed sneeze gives the game away the Doctor reluctantly crawls, stark naked, out from under the noblewoman's voluminous skirts.
"The Time Monster" does this when Benton is reverted from a baby back to an adult, naked and clueless. Cue an Everybody Laughs Ending.
Hal Sparks once did an entire episode of Talk Soup in the buff.
In an episode of Roseanne the main characters discover that they can look from their window into their neighbours' home and see the elderly neighbours walking around in the nude. Naturally they spend their every waking moment obsessed with this view.
Supernatural has Cupid, who caused some very awkward moments when he hugs people...
In a rare case of this trope being invoked entirely though dialogue, this classic scene from Extras in which Patrick Stewart recounts a plot which involves women's clothes falling off. This led to the memetic line "I've seen everything. I've seen it all."
In the Bitter Suite episode of Xena: Warrior Princess, Xena and Gabrielle wake up in Illusia completely naked. Gabrielle notices her own nudity when she is musing over whether or not she is in the Eluysian Fields before running away, hands over her chest protectively, to avoid being seen nude by Joxer, who later provides her with clothes. Xena is initially dressed in blue and beige robes by her nemesis Calisto, but when she confronts Ares, the God of War strips her completely naked with two quick sword slashes, exposing her firm, shapely body before his minions, much to her quiet yet humorous anger.
In Charmed, Piper and Phoebe arrive to rescue Prue from a kidnapper who had dealings with demons, only to find that Prue and the kidnapper (who only wanted Prue's help against the demons) have just had sex;
Prue: Uh... What are you guys doing here? Phoebe: We're rescuing you from the tall, dark, and naked man. Prue: I told you to stay away. Phoebe: Yeah, now I know why. He is yummy.
Bones; in the Season 7 premiere, Angela becomes very interested when she learns that Brennan took a photo of Booth making an omelet while naked.
Family Feud: "Name something that a burglar would not want to see when he breaks into a house." Contestant's answer? NEKKID GRANDMA!
Richard Hatch from the first season of Survivor infamously went around naked when he celebrated his birthday on the island. Fridge Brilliance sets in when Sean notes that he is celebrating in his "birthday suit".
In the Babylon 5 episode "Sic Transit Vir", Ivanova has a "Not Wearing Pants" Dream in which she's wearing, in fact, nothing at all. Claudia Christian was given the option of doing the scene in her nightclothes or completely starkers; citing this trope, she went for starkers. Now that's dedication.
Rizzoli & Isles: In "This Is How A Heart Breaks", Maura dates a sculptor who sculpts in the nude.
Saturday Night Live had Rob Schneider as "The Sensitive Naked Guy" - his son complains about teasing from his classmates, and he concludes it's because his son's classmates have a problem, not that his dad is always inappropriately naked.
Da Yoopers' first full Christmas album was titled Naked Elves in Cowboy Boots. Yes, it had a song about the titular elves.
"I Wanna Be Naked" by Screeching Weasel, in which Ben Weasel sings about the benefits of being a nudist (not getting made fun of for how you dress, not wasting time deciding what to wear, etc.)
In a 2002 episode of Raw, Chris Jericho and Christian got their clothes stolen by the Dudley Boyz and spent much of the show backstage wearing only towels trying to find them. Later, when they're on the stage, Spike Dudley rips their towels off.
Saints Row 2 gives the player the option of removing all of the player character's clothing, complete with Pixellation. You can then play a streaking minigame with the goal of disgusting as many people as possible. The fact that it keeps score for this adds to the game's Refuge in Audacity tendencies.
Katamari Damacy: Lalala is simply 'the nudist cousin'. While other cousins are distinguished by their colorful clothes, unique shapes and/or quirky personalities, she's just naked. And sunburnt from running around naked all the time.
Dragon Age allows you to unequip character armor and robes at any time (even in the middle of battle). Players who pay attention to character approval bars will see a Face-Heel Turn coming along and wisely remove their armor if they're planning on leaving with it (thus making angry, drama-charged moments gagfests while you stare at your party members' adult diapers). See this video for the dangers of leaving party members in the flesh.
Neverwinter Nights: Hordes of the Underdark contained a dungeon where your character's clothes are stolen by a Mimic, which might leave you with no replacement gear if you only carry one suit of armor. Aribeth finds the whole thing quite amusing.
Ran Yakumo of Touhou, according to Fanon, likes to randomly shed her clothes and become the "Suppa Tenko" (Naked Heaven Fox). In one particular fan comic, exposure to Chen's cuteness causes her to go Suppa Tenko via Clothing Damage.
"...one particular fan comic"? There's an entire pool of Suppa Tenko jokes on Danbooru, many of them Chen-induced. Since Tenshi's name can be written as "Tenko", sometimes she joins the fun just for the hell of it.
Yusuf Amir: ...things went a bit crazy and, uh, I somehow lost my pants! Hahaha!
Abdul Amir: Things do not look good, son.
Yusuf Amir: Don't judge a book by its cover, father. That's what you taught me.
Abdul Amir: When a book is called guns... drugs... hookers... and no pants... I think I don't need to read it.
In the VCPR Radio Station of Grand Theft Auto: Vice City, one of the segments, about Morality, features among the panelists a rather amoral nudist who always interrupted the arguments to say nudism is always the best solution for eveything. He was demanded to stay behind a divider so he wouldn't squick the other ones (a soccer mom and a fundamentalist corrupt televangelist), but he disobeys anyway, trying to hug people on more than one occasion ("Don't be shy, Please! We all got one! That means I'm happy!"). By the end of the segment, the televangelist (after delivering a Hannibal Lecture about his own amoral ventures) gets fed up with the guy and shoots him the crotch.
Maurice Chavez: Dios mío, you shot him! There's blood and pubic hair all over the studio!!
Three Nords encountered during the game have run afoul of witches, who leave them naked in the wilderness. This is referenced by a naked Nord in the Tribunal expansion who insists he's never met any witches; it's just really hot out.
Pokemon Heart Gold and Soul Silver have a notorious cutscene where Silver becomes incensed at the sight of the player character in a Team Rocket uniform and rips it off of them then and there. In the game, the player character is wearing their own clothes under the Rocket uniform. In the fan art of that scene... not so much.
Reality On The Norm: Guido, a nudist who is an eternal embarrassment to his brother, but thankfully usually stays at home (though apparently he helps his brother in his restaurant. While wearing no clothes, yes.)
In the original Japanese version of EarthBound, in Magicant, Ness is naked.
In The Sims, a Sim who happens to catch sight of (or even just be in the same room as) a nude Sim will react with a startled scream, even if those two Sims just Woohooed.
Silent Hill 3: Konami Code + This Trope = Douglas wearing only boxers 'neath his trenchcoat.
The Bare Pit (NSFW if your workplace objects to naked people, otherwise pretty wholesome), originally titled Loxie and Zoot, is an Australian webcomic that takes place at a nudist resort, now celebrating 10 years of online publication. Completely subverts the majority of the trope, although some of the more obvious storylines (a pervert with a camera, a prude trying to harass the resort, etc) are still used.
The comic's creator even added his own Naked People Are Funny plot in its longest storyline — or rather, about six of them: A bump to the head causes Loxie's mother (a rather prudish, intolerant woman) to decide to join in. Because her daughter and son-in-law both know full well that once she comes to her senses she will regret it, they do their best to keep her dressed and hidden (and are failing miserably). Right afterwards, Loxie's prudish sister gets stuck at the resort, and upon falling asleep, goes sleepwalking (naked, of course). Loxie's nephews are using their mother's nap to sneak around trying to peep (and are failing miserably). Loxie's niece was suckered by another girl into going naked by wearing a wig to hide her identity (and is failing miserably). Loxie's father and brother in law are sneaking off to fish during all this (and are failing miserably). They most recently lost a "you gotta stay naked" vs "you gotta stay clothed" bet with some regulars, and are currently trying to evade a pissed off emu who isn't happy that they bailed out after losing (and are failing miserably). * phew* . At last count that makes 5 or 6 storylines going on all at once, all destined to fail at the exact same time, Benny Hill style.
A minor lawyer character in Unshelved is a nudist. His idea of a Halloween costume is to put on clothing. He is a good example of the "Right-To-Nuder" subtype, as he spends all day at the library arguing about his First Amendment rights.
Or maybe not - he shows up in one storyline wearing a full suit and tie: that is, the storyline in the nudist colony.
Quentyn, hero of Tales of the Questor has some problems keeping his pants on, either having pursuers grab at his clothing or needing to change clothing in a hurry. The humor comes less from the nudity itself, as it is to various reactions to the matter by the Kid Hero, who's a bit modest around women. The concept is essentially distilled by the time he goes to human territories, where Samantha warns Quentyn against peeking while she showers in a near-by bush, even though she's about as interesting as a naked rat to Quentyn. Likewise, Quentyn starts to panic when his bath is interrupted by a female maidservant, yet she doesn't think anything of looking at him.
Played straight in I Was Kidnapped by Lesbian Pirates from Outer Space when the captain identifies a birthmark on their new guest. Responses included asking a naked lesbian how she managed to check another woman for birthmarks. She insists it's not important.
While Dominic Deegan has an oft-times nude country of werewolves, they are not this trope. No, that would be Brian, the fat guy who likes to do his stretches at the cruise ship's pool. Naked.
When loveable megalomaniac and Friendly Hostility star Collin needs to take a break from his stressful life, he takes boyfriend, slave, and fridge-dwelling demon to the beach. Still unable to relax, Collin strips nude...on a non-nude beach. Those poor nuns....
Sluggy Freelance has played with this. An early gag pointed out the problem with nudist camps is lack of quality control. Elsewhere a chapter (and later a book) is titled "Game Called on Account of Naked Chick."
Demon Eater plays with it. Demons don't reproduce with sexual organs, but there is a group that want to be like humans. They don't quite get the appearance right, with one of them being an anatomically correct male but without skin, while another is an anatomically correct albino female... without a head.
Wil of Questionable Content goes on a vision quest and runs into a guy from a nearby senior nudist colony, at first mistaking him for his "spirit animal". When he relays this story to the members of the reservation, they dub him "Wil Talks-to-Dongs".
Inverted in the Insecticomics: Because Transformers are ordinarily nude, there is humor value in putting them in clothing.
Used in Survival of the Fittest with Sam Sorenson, who spent a good portion of his time on the island running around naked.
Sam: Umm...hi! You see, I was abducted from my nudist cruise and sent here for some comedic purposes with no clothes, I really do need help and no do not worry about my modesty for being a nudist I have gone all my life with people staring at my dingaling! Really, just all bow down before the wrath of Kahn! Kahn!
Gaia Online's Gino Gambino gets possessed by a god with no nudity taboo during the Demonbusters event. Said god promptly hams it up with lines like "FEELS GOOD, MAN!" and goofy poses. Since Gino straddles the line between Bishounen and malnourished, this may double as Fanservice or Fan Disservice.
Oddly enough, the Overseer in his own shape wears clothes.
Garnet And Gure: This cartoon short showcases the production of a charity nudie-calendar, which is disrupted by a fairly repulsive character who insists that he is to pose alongside one of the ladies.
Cartman on South Park walks across the mainstage at a fair naked, because he's convinced himself that he has magic ninja powers and can become invisible.
Happens to Homer quite frequently on The Simpsons. In one instance, Homer and Marge try to have sex at a mini-golf course, and end up having to make it home naked after losing their clothes.
This also comes to mind:
Ned Flanders: Homer, you've met my parents.
Homer: Not naked I haven't.
Every character on Family Guy has been naked for a laugh at least once. Usually it's Peter Griffin, whose gut hangs down low enough to cover his genitals. In one episode, they find out their neighbors are nudists, and most of the family ends up naked in an attempt to show acceptance. In a later episode, they run into the nudists at a KISS concert - wearing nothing but face paint and guitars, of course.
From the episode "Deep Throats:"
Stewie:(to Lois and Peter) "Well, you two are busy bein' nude, so, um, we'll just head out and um...let you be nude.
In the episode where Peter becomes a cigarette company executive, he has the kitchen coated in Teflon for easy cleaning. Everyone falls over, as Peter remarks that he didn't think they'd do the floor too. Then Stewie slides by on his butt, bare naked, and happily announces "I'm Nudes on Ice!"
Bill Clinton's "This is one Fine Day to Be Nude" gag comes to mind.
Pretty much every main character on Spongebob Squarepants has been naked quite frequently at one point too. Mostly it's the titular character, who, ironically has concealed genitals even though he was ashamed in earlier episodes that involved him being nude. In the episode All That Glitters, he had to sell everything to buy a new spatula, INCLUDING his clothes. He arrives to work the next day completely naked, much to Krabs' dismay and Squidward's delight.
In the episode "Pranks a Lot," a bus stops beside a naked Spongebob and Patrick.
Tom: "And on your right, if you look, you'll see two naked guys fighting over a can of paint!"
Everyone on the bus:(laugh hysterically)
Later in the episode when Mr. Krabs notices that Spongebob and Patrick are nude:
Mr. Krabs: "Uh...any particular reason you boys are naked?"
The Fairly Oddparents has at least two examples of this. The first one is Timmy wishing that instead of having to take a bath he could be at his favorite comic book store. They do indeed poof him out of the bathtub and into the comic book store; but forgot to dress him. As a result, he has to make his way home through the town completely naked. Another example is when Timmy jumped off of a high dive board into a pool. He lost his swimming trunks and comes out of the pool where everyone there sees Timmy in the buff.
American Dad! has had many examples. One of the best was during an episode where Hayley and Klaus were having a dare challenge and one of Klaus's dares had Hayley run about the front yard completely naked (With the exception of her headband, peace sign necklace and wristband). Roger's head took up most of the center but when you can see Hayley the only thing covering her body is a censor blur. See for yourself.
The Mask did this in an episode called Flight as a Feather which detailed the Mask trying to find the feather that goes in his hat; while searching for it he foils an angry stripper named Cookie BaBoom trying to blow up Mayor Tilton along with herself for ending their affair with dynamite strapped over her private parts. When the Mask pulls them off he sends her into a whirlwind like the Taz-Manian devil, and when Kellaway and Doyle show up to arrest the Mask, the Mask stops Cookie's spinning, exposing her naked body to the cops, causing both men to faint. The Mask then says to her "Don't I know you from traffic school?"
Ren and Stimpy: This sometimes happen to the the title characters themselves. Old Man Hunger is portrayed as naked.
In Rugrats episode 54: Naked Tommy, Tommy wants to shed his clothes to be like his dog, Spike, so he tries out naturism. He also wants Phil & Lil to do it too, so they do so. Chuckie doesn't want to.
Later she shows up at the non-nudist beach with some surfers - and without her clothes - with a surfboard obscuring her nudity. Grandpa Phil is not amused:
Gertie: Up the establishment! Phil: Aw, Pookie, nobody wants to see that! Gertie:(laughs)
In The Angry Beavers episode "Sans-A-Pelt", Norb and Dag lose their fur after a failed magic trick exposing their naked bodies.
Loriot's animated sketch "Die Herren im Bad" ("The Gentlemen in the Bathtub").
The episode "Over Exposed" in 6teen, where Jonesy ends up seeing Jen naked. They both freak out over it, swearing never to mention it again, but word gets out and awkwardness ensues. Eventually another girl shows Jen a picture of Jonesy naked in order to make her feel comfortable again.
Dexter's Laboratory: Dexter's nakedness including him in his underwear, is kind of funny in some episodes.
I Am Weasel: I.R. Baboon possesses a bright red butt that he never wears pants to cover, and therefore is ridiculed for it
Theres also I.B. Red Guy who is a regular on the show, while still keeping his role on Cow and Chicken. The Red Guy is truly butt naked, for a demon no doubt?
His first introduction in the pilot/short: "HELLOOOOO!!! It's ME, the devil!" He only assumes the title "Red Guy" when the show went into full production.
Codename: Kids Next Door: Tommy Gilligan was a victim of this trope. In one episode he makes the wrong interpretation of what a birthday suit is, and in another episode, somewhat more deliberately, he's trying to avoid getting a bath.
It happened to the whole team (except Numbuh Four) in "Operation: A.R.C.T.I.C." when they were hit by their own ship's missile. (Made even worse by the fact that they were at, well, the Actic.) Numbuh Two tried to make light of the situation by saying that at least now they knew it worked.
And then there was "Operation: B.U.T.T." It wasn't all too funny for Numbuh One, of course. (The Delightful Children had a robot swipe his shorts while he was at the beach, and then take his picture. Before he even found out they had the picture, everyone laughed at him. Then he finally made it home, and it got worse. After he got their blackmail note and left to deal with them, his teamates found it, and even ''they'' couldn't help but laugh before they decided to go help him.)
King of the Hill: Hank gets caught in a passing tornado holding his dear life to a telephone pole. His clothes slowly tears off leaving him nude. As the eye passes, he chooses a potted cactus over a Texas flag to cover himself to make his way to the shelter.
Avatar: The Last Airbender: Iroh is seen in a hotspring relaxing. Zuko becomes impatient and tells him to get out and, as Iroh begins to come out, Zuko is disgusted by the sight and tells him to get back in for a few more minutes before leaving. Zuko's hand censors him.
Although he himself never cracks a smile about it, Kick Buttowski ends up naked on the show...so much it's hard to count. This is met with fear, indifference or laughter.
In the Tiny Toon Adventures short "A Bacon Strip", from the episode "The Acme Acres Zone", Plucky tricks Hamton into skinny-dipping in Montana Max's pool. When Hamton reluctantly does so, Max steals his clothes, and Plucky runs off, lest Max get him in trouble too. Hamton is then forced to make his way home while trying to conceal his nudity. Once he gets there, he finds a surprise birthday party waiting for him. (By now, Hampton has been embarassed too much to be humiliated any further, and takes it in stride, saying, "At least I came in my birthday suit.")
In the Teen Titans Go! episode "Laundry Day", Raven snatches the other Titans clothes to wash them; leaving them in the buff. Robin gets locked out of the tower and gets swarmed by bees and fangirls with cameraphones.
There exists a police video wherein two drunk women pulled over by the police proceed to strip naked and play in some nearby sprinklers. Jay Leno later ran it on The Tonight Show, where it was played for laughs.

One of Spike Milligan's favourite pranks was to turn up at the door of a friend's flat or house nude and say: "Do you know the address of a good tailor?" He claimed in Adolf Hilter My Part In His Downfall that this originated with one of his comrades in the artillery (the man's alternative punchline was "Gentlemen, I believe there is a thief in the battery!")
One word: streakers. They run around naked in public places to magnetize people's attention. Most of the times they get stopped in their tracks by the policemen, but once you see one of them, get ready to laugh really hard.
Waldorf: Well, how do you feel about nudity? Statler: Well, personally, it always left me cold. Both: Do-ho-ho-ho-hoh!
