In Shaman King, Tokagero states his mother had given him "her own flesh" so he would survive. A little bit later on the story, we find out he really meant it.
During Sanji's flashback in the One Piece, he and the pirate Zeff are stranded at sea for over two months. Though Sanji rationed his share of the food they'd washed ashore with, it only lasts him 25 days. 45 days later, young Sanji tries to kill Zeff and take his seemingly large remaining share of food, only to find that it was all treasure, and the pirate chef had been forced to eat his own foot at the beginning of their time stranded, secretly giving Sanji all the food to keep the boy alive. It's a horrifying reveal for the boy and pretty clearly illustrates why he stays with the "old crap-geezer". In the anime adaption, the chef cuts off his foot in his attempt to save Sanji because it was trapped, and spends the whole time eating nothing.
In one episode of Kino's Journey, Kino encounters some snowed-in traders. Almost starving to death, they had eaten their cargo. Turns out they were slavers. Connect the dots...
It's heavily implied by a flashback in Mobile Suit Gundam 00 that Allelujah engaged in this as a boy, during an early appearance of his evil split personality, Hallelujah. Allejuah was trapped on a ship with his fellow tykebombs, and they had no food and were starving to death. Cut to a grinning Hallejuah with blood dripping down his shirt.
Asura. The Kanshō famine forced the titular character's own mother attempted to eat Asura, as a baby. Asura himself perform cannibalism as a mean of survival until he met a monk. Eight years have passed. Eight years of pure human flesh and blood.
Priscilla from Claymore. After she killed her yoma infected father, she was trapped in their house for a month and is implied to have eaten part of his corpse.

In Pocket God issue #23, half of the tribe is trekking through the desert with their provisions running low. Kinsee gets so hungry, she considers eating one the other pygmies. While they can resurrect from death, they keep her from doing it because they don't want to be cannibals.
In Invincible, a bunch of evil alternate Invincibles were manipulated by Angstrom Levy, who sent them to a desolate wasteland with nothing in it but sand when he was through. Much later, we see what happened to them: at first, they killed and ate the least popular guy because everyone was starving, but one of them went insane and started killing and eating all the others.
The Decepticons under Starscream's command have degenerated to this in The Transformers IDW, killing each other for parts and energon. Megatron is not amused when sees his troops in this condition.
Ravenous, which was a take on the wendigo where anyone who eats people gains power and life force? Spawning possibly the best closing line of any movie: As the two men are caught in a bear trap, the villain says "If you die first, I am definitely going to eat you. The question is, if I die first... what are YOU going to do?"
In the movie Gulag, when the prisoners are planning their escape, it is suggested that they take a 'sandwich' with them; that is, someone weak who will probably die on the ice so they will be able to eat him.
The Peter Jackson take on The Lord of the Rings: The Two Towers has a horde of Uruk-Hai who, after days of cross-country running, powered by moldy bread, start eyeing their Hobbit cargo. They end up settling for one of their own. This does not suppose that the Uruk-Hai have anything remotely resembling refined tastes in cuisine.
By this point the warband is composed of both Uruk-Hai and regular orcs, the ones that look more scrawny and hunch over. The orcs want to carve up the Hobbits but the scene plays up the discipline of the Uruk-Hai since Saruman ordered them to bring them back "alive and unspoiled". Of course, an orc being an orc, he draws his blade on the much stronger Uruk-Hai and gets gutted. "Looks like meat's back on our menu, boys!"
In the original My Bloody Valentine it's revealed Harry Warden ate his companions while trapped in the collapsed mine. The remake downgrades this into killing them to conserve oxygen.
Subverted heavily in Wagons East! As the ex-pioneers grow increasingly worried when they think their guide led the historical Donner party, a blizzard hits and the guide prepares a mysterious roast. Then, just as the lead ex-pioneer is in the middle of being horrified that they're eating the missing member of their party, the assumed roast walks up and asks if anyone's seen his cow. Resume feasting.
Monty Python and the Holy Grail: There is one animated sequence narrating when King Arthur and his knights were forced to eat Sir Robin's minstrels. There is a sort of Bilingual Bonus here - in the UK, 'Minstrels' are chocolate drops.
In Patch Adams the titular character plays with a skeleton, waving its hands around and gives a Shout-Out to this trope along the lines of "Donner! Donner! Party of 15 over here! Donner! Donner!"
Brought up in The Way Back. Seven men have escaped a gulag, and one asks the group's leader who he thinks will die first. The leader is confused and then horrified when the other guy says he assumed they'd brought so many people so they'd have something to eat. Fortunately it never gets that far.
Discussed in The Shining, where Jack (already a bit of a ghoul before going full-on Ax-Crazy), decides to tell his young son the story of the Donner Party while driving the family up to the secluded hotel in the mountains.
The Areas of My Expertise promises a cash reward to anyone who can find the Donner Party. If you can eat them all by yourself, you get double the prize!
Count Ugolino, of Inferno, is trapped inside his own tower, and ends up eating his children. Which is why he shows up in the Inferno. The only consolation in this is that he gets to gnaw for eternity on the head of the bastard who put him there, because even Hell has a sense of honor.
The John Wyndham short story "Survival" is about a group of people marooned for a year on a space station. As their desperation increases, they resort first to drawing lots, then to cannibalizing the losers' frozen bodies. When rescuers finally arrive, the one demented survivor sees them only as food. The last survivor having escaped the lottery for being eaten by claiming 'there are two people in me' - she was a pregnant woman. The last line is when rescue arrives is nicely chilling — "Look baby, food".
In The Road by Cormac McCarthy, an unnamed calamity has pretty much blocked out the sun and killed most of the life on Earth. Human survivors resort to eating each other, keeping captives as food stores and amputating their limbs, presumably to keep the rest of the meat fresh. This also brings new meaning to referring to a pregnant woman as having a "bun in the oven".
The short story "Survivor Type" (in the Skeleton Crew collection) involves a surgeon/drug mule who gets shipwrecked on a small rocky island. After running out of food, he eventually has to resort to cannibalism...on himself. Fortunately, he has plenty of heroin with which to dull the pain when he starts cutting bits off himself to eat...
In The Stand, Lloyd, who's locked up in jail when the superflu hits, winds up dining on the guy in the next cell before he's rescued.
Jessika Hendricks in World War Z relates to the interviewer how, encouraged by the mass media, many people attempted to escape the Zombie Apocalypse by traveling north into Canada, where the cold winter weather would freeze and immobilize the undead. Few if any of these refugees had any notion of how to live off the land or survive in severe winter weather, and when supplies ran low, the only remaining source of food came from their own dead.
In Lord Byron's Narrative PoemDon Juan, the heroes are lost at sea and forced to eat some of their crewmembers, including Juan's beloved teacher and his dog. The grim scene is handled with touches of Black Comedy — one man avoids being eaten because he has a special "present" given to him by some prostitutes.
The fantasy novel The Warrior's Return averts this in a scene where a group of snowed-in and starving soldiers, faced with their first dead comrade, decide (with a little prompting from their protagonist commanding officer) not to do this because they're all too aware of the possible consequences of starting to think of each other as food and instead give the deceased as decent a funeral as they can manage.
And then we murdered the bo'sun tight, And he much resembled pig; Then we wittled free, did the cook and me, On the crew of the captain's gig.
Mark Twain wrote a classic subversion of the trope, "Cannibalism in the Cars" in which a group of congressmen are snowed in, and naturally establish a sub-commitee to select the juiciest candidates.
Richard Olson's historical novel The Ungodly, about (yes) the Donner Party.
In Haunted by Chuck Palahniuk, the writers stuck in Mr. Whittier's retreat have to resort to this...but really, it's their own damn fault. Once they realized they were stuck in a building for three months, each writer began sabotaging all the dried food to make the experience more marketable. Sure enough, eventually they ran out. When people began dying they had to resort to cannibalism , although it's implied that in at least one case the process was "sped up." The worst case is the first case.
In the Gaunt's Ghosts novel His Last Command, Gaunt discovers that the cooks of Fortis Binary's units have been taking meat from corpses to be used in the cooking.
The protagonist of Robert A. Heinlein's The Cat Who Walks Through Walls is a veteran of a squad that ate their commanding officer during the war (He was already dead, and they were dying of starvation). This dark bit of his history jump-starts the plot, then is removed by Time Travel (someone went back in time and hid emergency rations under the body).
Edgar Allan Poe: In The Narrative of Arthur Gordon Pym of Nantucket, the heroes are lost at sea, and after first refusing human meat when they happen upon another ship that has suffered the same fate, they eventually resort to drawing lots and killing and eating one of their own. Fittingly, the victim is the same man who suggested cannibalism in the first place.
A similar event is subverted in the opening chapter of The Island of Doctor Moreau, in which Prendick and two others are adrift in a dingy. They draw lots to determine who'll be eaten, but the loser fights back and both of the other men fall overboard and sink like stones, leaving Prendick alone.
In one of the Aubrey-Maturin novels by Patrick O'Brian, the heroes and some crewmembers are stranded in a lifeboat for an extended period of time. One man dies, and the next morning there has been an obvious bite taken out of his leg, but everyone politely refrains from mentioning it. (They are rescued before things get much worse.)
The Sten series has the crew of the ill-fated starship Discovery I, which suffered severe damage in an accident. First the survivors ate the dead. When they realized that wouldn't be enough to last them to the nearest inhabited planet, everyone very quickly came up with a reason they were vital to the ship's continued operation. Those who didn't come up with a reason quickly enough ended up in the soup.
In Dreams Of Joy, Joy goes to visit her friends on the commune she lives on in 1950s China. She returns to see her husband and his family staring at something on the table. It's another woman's baby, which is close to death. She takes the baby back to the other woman's house and finds them at the table staring at her baby. The practice was called Swap Child, Make Food, when families would trade babies (presumably no one wants to eat their own baby) that are close to death and eat them.
A recurring element in A Song of Ice and Fire when food runs out. When Stannis' army is snowed in, several soldiers kill and eat another and are executed for it, while in Astapor even its rulers were accused of it as the city starved. There's also suspicion about exactly what kinds of meat go into the bowls of "brown" (cheap stew) they sell in King's Landing, short on food due to the war. And winter has only just started.
Euron Crow's Eye: They refused to eat of their friendís flesh at first, but when they grew hungry enough they had a change of heart. Men are meat.
Ser Alliser Thorne of the Night's Watch claimed to have been forced to resort to cannibalism when his patrol got stuck beyond the Wall for months. Given that he's master-at-arms, it's likely that the Night's Watch considers this something of an occupational hazard.
This was just barely averted during the Siege of Storm's End during Robert's Rebellion. As the siege went on and on, a group of soldiers attempted to desert and surrender to their enemies. Stannis was going to execute them, but his maester advised him to hold onto the men, in case the food shortage became bad enough that they would need to eat them. Only the fact that the smuggler Davos managed to slip through the blockade and bring in a shipment of food not long before the end of the war kept it from happening.
The Star Wars Expanded UniverseGalaxy of Fear book "The Hunger." The main characters hide out on Dagobah where they encounter a small tribe that calls themselves The Children. The Children take in one of the main party's wounded red shirts for healing and claim they were forced to amputate one of his limbs. Later on, the wounded man is found to have two limbs missing and another red shirt dies mysteriously. One character almost has a bowl of the tasty-smelling stew they're cooking but stops when he notices the ring in it. It turns out that the Children are the last remains of a stranded survey team - when the team members were hit with starvation, the desperate parents fed the toddler kids the flesh of the dead until no adults were left. The children managed to survive by eating fungus and any of their own dead, and still remember the yummy taste their parents used to give them, interpreting it as an act of love. The tribe's later My God, What Have I Done? moment only serves to increase the horror.
In Lucifer's Hammer, the remnants of a National Guard unit start off only killing and eating people because they have a hard time finding anything to eat. Later, they descend into I'm a Humanitarian territory, and use forced-cannibalism ("You can eat it, or you can be eaten. Your choice.") as a sadistic recruiting tool, since cannibalism "indelibly marks a person, on their soul", making said persons permanently pariah with any "decent" folk.
Pretty much the exact same thing happens in the first Emberverse novel, Dies the Fire, where the sudden collapse of infrastructure (including the end of guns) leaves most people with no stockpiles of food and no ability to hunt food. Well, most food except for a certain large animal that has two legs and is easily caught... After the "Eaters" descend into active hunting, they are pretty much killed on sight and shown no quarter, even by the titular good factions.
In Piers Anthony's Bio of a Space Tyrant series, the titular space tyrant's journey to Jupiter as a refugee from Callisto is chronicled in Refugee, in which the space bubble he and his family are on is attacked multiple times by roving gangs of Space Pirates who seldom leave without murdering or raping anyone (and sometimes they commit rape and murder). It eventually gets to the point where every adult male has been murdered, the only ones left to pilot the bubble are inept women, and their food supplies are running low. Eventually, they decide upon eating the corpses of the men "buried" on the hull for food.
In Gene Wolfe's Book of the Short Sun, it is heavily implied that the Vironese ate each other on the landers leaving the Whorl since they on weren't equipped with proper supplies.
In Life of Pi, this is the nature of the alternate story Pi tells after being found. It also comes up in the narrative proper when he crosses paths with another stranded shipwreck victim, who pretends to be friendly just to get him to come close and then tries to kill and eat him. The tiger's name, Richard Parker, is a reference to the coincidence that multiple people with that name have happened to be involved in real cases of mutiny, shipwrecking and/or cannibalism.
Part of the backstory of Courtship Rite. The inhabitants of the hostile Lost Colony of Geta have been a Donner Party so many times over the centuries that cannibalism has actually become an accepted and normal part of their society.
Discussed in The Thin Man, when Nick tells Gilbert a long and rambling story about frontier cannibalism. Reportedly, Nick's story was the inspiration for the movie Ravenous (listed above), which it very closely resembles.
In Brian Evenson's post-apocalyptic short story "An Accounting", a diplomat goes on a trade mission to the Midwest, meets a group of tribesmen, and convinces them that he's Jesus. He does this partly by sharing his dog, which he's already killed to ward off starvation. Since they worship him, they're more than willing to sacrifice one or two of their own for the same purpose.
Happens to the crew members stranded at sea in Carol Birch's Jamrach's Menagerie. Initially, they only eat the men who have died of illness or starvation, but then...
Live Action TV
Naturally, Monty Python's Flying Circus approached the topic with its usual levels of taste and restraint — twice in one episode (#26, "The Queen Will Be Watching"): first in the Lifeboat Sketch, followed by the infamous Undertaker's Sketch, which was so outrageous that the execs at the BBC actually demanded a rewrite showing the studio audience storming the stage in disgust, which is honestly a very funny way of ending the scene. On one of the albums, the Lifeboat Sketch is followed by an irate phone call from a Royal Navy officer who objects to the suggestion of cannibalism in the Navy, on the grounds that "the Navy now has the problem relatively under control," and it's now apparently the R.A.F which has a cannibalism-related problem. See also: the Real Life section of this page concerning cannibalism and British sailors.
One episode of Medium opens with two men, one clean and in a suit, the other disheveled, eating in a fancy dining room. The disheveled man keeps asking what the great tasting meat dish is and the other finally says "It's you. More specifically, it's your right leg. Go on, take a look." At this point, the man looks down to see his right leg amputated and Allison wakes up. Later on, it's revealed that both men were part of a group of Vietnam POWs who ate another soldier who was dying so they could survive.
Played for laughs on The Colbert Report during a story about a food shortage - Colbert predicts that his 2012 presidential campaign will be sponsored by 'Sour Cream And Man' flavored Doritos, sees his stage manager in Meat-O-Vision, and ends the show by apparently eating him (the manager having 'tendered' his resignation).
One episode had him coming back as a ghost, a la A Christmas Carol. At the end of the show, Stephen Colbert eats his ghost.
Invoked in this little exchange from Simon and River's playtime flashback during the Firefly episode "Safe." To put things in perspective, they're playing a wargame involving dinosaurs.

Invoked in season 2 of LOST when Sawyer, Jin, and Michael are captured by the survivors from the tail of the plane, who are discussing what to do with them:
Sawyer: I think they're talking about whether or not they should eat us.
In The Goodies episode "The End", after the Goodies are sealed inside their office building, Tim and Graeme plan to kill and eat Bill. The plan is abandoned after Bill suggests eating the furniture.
Graeme: There isn't enough food here for three of us to survive for long. But there might be enough...for two.
Tim: Graeme! You don't mean —
Tim: To eat...you?
Graeme: What? No! ...I'm doing the sauce. (points to Bill, making beheading motion)
Ruth-Anne on Northern Exposure shuns Holling for a while when she finds out his grandfather ate hers.
This trope is the catalyst of the storyline on the Hong Kong drama When Heaven Burns, when four young men are lost on a mountaineering trip and forced to murder one of their own to survive. The drama then explores the implications and trauma that the incident had on them.
Parodied in a That Mitchell and Webb Look sketch about Antarctic explorers, where they're on the brink of starvation, but the idea of starting on the hamper of Christmas food before it's actually Christmas is treated like this trope. "We are Englishmen, not animals!" Eventually the captain gives in to despair after it transpires that his men have already eaten the advent calendar and the carrot he was saving for the nose of his snowman.
A two-part "The Slobs" sketch from Henry Enfield And Chums features the titular characters winning the lottery, getting on a plane, and bringing it down after eating way too much food. A short while later, the two of them have eaten the entirety of the passengers and crew, then start eating each other (At the same time).
Not the Nine O'Clock News had a sketch where two shamefaced survivors of a plane crash similar to the famous Andes case (see below) are interviewed about it, gradually being led to describe how they decided to go into the plane... and retrieve the airline food, because they'd already eaten all the corpses.
Parodied in Wings, Fay's bus crashes during a Murder Mystery tour. "And I don't even want to talk about what happened when we ran out of food, it was like a soccer game in the Andes."
Saturday Night Live: One of the "Delicious Dish" sketches about a fictional NPR cooking show featured host Kelsey Grammer playing nature expert Graham Stanslerthere to share tips on finding food in the wilderness. He first recommends "GORP" (granola, oatmeal, raisins and peanuts) and bark, moss and grubs when that runs out.
Graham Stansler: Now, if you work your way a little higher on the mountain, pickings get a little slimmer. Maybe some lichens, some wet soil. But soon, that's gone, too, and to make matters worse, you realize you're lost, and you're starting to suffer from severe hypothermia... And then night sets in, and you're huddling in a snow cave drinking your own urine!... After a couple of days, you're dehydrated! You've eaten your boot leather, and you're going blind from hunger! That's when you get desperate! You have to find something to eat! So, you and your buddies draw straws to see which one of you guys isn't coming down the mountain!... Then, in perhaps your lowest moment, you cheat to make sure it's not going to be you. And it turns out to be... Carl! The godfather of your children!... You know, it's really amazing how... how easy it is... how easy it is to turn your back on God! How easy it is to steal a little extra Carl while the others aren't looking! And then a chopper comes and rescues everyone! But for the rest of your life, everything you eat... tastes a little like Carl. Gamey, a little stringy.
Teri Rialto: Okay... well, thank you very much for coming, Graham.
Graham Stansler: Oh, sure. And thanks for having me, ladies. Remember: GORP stands for granola, oatmeal... shoe leather, urine... and Carl!
Frank: The time may come when one of us has to make a difficult decision, and when that happens... I'd rather be the one with the knife.
A Cold Open sketch from The Kids in the Hall shows a man on trial for eating (well, sampling) each of the other 112 passengers on his plane, even though they never left the runway. "You are the sole survivor of a thirty-five-minute delay!"
'Timothy' by The Buoys is a song about three miners trapped in a cave-in, and only two of them are eventually rescued. The third miner, the eponymous 'Timothy' is missing. In the second verse, the narrator says that he's 'hungry as hell, no food to eat' and that his colleague Joe said he'd 'sell his soul for just a piece of meat'. The third verse describes how the narrator blacks out, and awakens when he's rescued, saying that his 'stomach was full as it could be and nobody ever got around to finding Timothy'. It's implied that the narrator and Joe ate Timothy before they were rescued. note One explanation has been offered that Timothy was a mule, not a person. That would explain why nobody seemed to care about finding him.
Little Boy Billee, by Ralph Steadman, deals with this: Guzzling Jack, Gorging Jimmy, and the title character all go sailing, but Jack and Jimmy eat all the food, and then decide to eat Billee. He just barely manages to dodge this fate because Big Damn Lord Nelson shows up at the last minute, hangs Jack and Jimmy, and makes Billee an admiral.
The somewhat obscure band Giant Squid have a song called Throwing a Donner Party.
'A Tale They Won't Believe' by Weddings Parties Anything is based on Alexander Pearce (in the Real Life section.) Every second verse or so sees another member in the group dispatched.
Parodied in Dilbert. The incompetent pilot of Dilbert's flight crashes into a mountain — the same one that he previously crashed into three times. In order to avoid frostbite, the pilot tells the passengers to beat themselves with meat tenderizers and to apply liberal amounts of Worcestershire sauce. The one person who realizes what's going on (Dogbert of course) saves them all by sending the pilot to get help from the village at the base of the mountain, via a snowball to the face. It's strongly implied since the first time, the Pilot got addicted to human flesh.
Parodied in Pearls Before Swine, when Pig thinks the Donner Party was an actual party. Goat tries to explain it to him:
Goat: Pig...they ate each other.
Pig: I would not re-hire that caterer.
Parodied in The Far Side. A group of men stranded at sea on a small boat have drawn straws to see who gets eaten. One of them is telling the man who drew the short straw that fair is fair and he must submit to his fate. This is despite the fact that one of their party is a dog.
Religion and Mythology
During one of the Biblical sieges of Israel, King Ahaziah was asked for help by a distressed woman who had made a pact with their neighbor to boil and eat their sons. Her problem? The neighbor had hidden her son away.
In the Book Of Deuteronomy, the Israelites are warned that if they turn away from their God and don't adhere to the laws and rules that were given to them, that this (among other chaos and tragedy) will happen. (On the flip side, they are also told that if they keep the faith and play by the rules, they will have prosperity and stability.)
Another really old example on tabooification of cannibalism, the Algonquian myth of the Wendigo, says that a human being that commits cannibalism can become a human-eating monster.
In his Twisted Metal: Black backstory, Mr. Grimm was forced to eat a fellow soldier while in Vietnam. He then kept the man's skull and wore it as a mask. If he wins the tournament however, Calypso offers him a mano-a-mano with the officer who put him in the situation to begin with... and Grimm realizes he acquired a taste for long pork. No explanation needed for what comes next.
An early level in The Suffering: Ties That Bind features a small Great Depression-era soup kitchen. According to the backstory and various hallucinations, the priest that ran the kitchen was so desperate to feed his starving congregation that he resorted to cooking up human corpses. Even worse, the always-hungry monsters inspired by the event now roam the area in the present.
In The Oregon Trail II, if you take the California Trail (and more specifically the Hastings Cut-Off if you're playing on higher difficulties) in 1846, you encounter the same snowstorm that the Donner Party got stuck in. The game also allows you to butcher a draft animal if you run out of food, although you don't get to cannibalize your wagonmates. The Dev Team Thinks of Everything!
The Donner Party is actually discussed in the 5th version. Talking about everything that happened to them except what they're most infamous for. When it gets to that part the narrator simply says "They did things to survive that I don't want to talk about." One of the kids says "I heard that they —" before being told to be quiet. They are mentioned briefly in the second version also.
In the iPod version of the game the leader of the Donner Party shows up in a town and gives your party food, insisting that they've got more than enough to spare. ...Yeah
Originally, if a member of a player's wagon train died while the train had reached starvation, the player's food supply was to increase slightly. One can guess where said food would have come from.
One that did make it to the final cut of a game was the "save person from drowning" event. You don't get a new party member, but you get food instead. It also has the same icon as hunting and fishing events...

In Drowtales, this happens all the time in the commoner classes. When food gets scarce, as it so often does in the drow's underground home and food costs raise, eventually slaves start costing less than food, causing many drow to resort rather quickly to eating their slaves. These slaves can be a wide range of species, from human, to elves and other drow.
In Off-White, The sledders had to resort to eating the dogs. Considering in this world the dogs are intelligent...

Jimbo: There's only one answer: eat Eric Roberts.
Mayor: [thoughtfully] Yes, uh-of course. Nobody gives a shit about Eric Roberts.
One seafaring episode features Peter, Cleveland, Quagmire, and Joe clinging to a makeshift life raft made from inflatable sex dolls. (No prize for guessing the identity of their owner.) While one of the others complains of hunger, Peter covertly munches on something with his back turned. The paraplegic Joe notices this and wrests the food away, only to discover that Peter has devoured his (Joe's) useless and unfelt legs, leaving bloody stumps. Joe freaks out, of course.
And in the Y2K-bug apocalypse episode, Tom Tucker and Diane Simmons eat their news-crew colleague, Tricia Takanawa.
On an episode of American Dad!, the family and a tour guide are shipwrecked on an island inhabited by a bunch of guys who want to hunt them for sport. While fleeing from the hunters, the tour guide is crushed in a cave in, trapping the family within. Francine, Steve, and Haley all decide that they should eat her since she has died, but Stan holds out on moral grounds until he finds out she is an organ donor on her drivers license. After they get through eating her, the hunters dig them out, and it is revealed that it was just a "Most Dangerous Game Theme Park", and they weren't in any danger. The Smiths agree to never speak of this again.
Played with on Kick Buttowski where all the school children on the bus got caught in a snow storm, they all had food with them... but when Jackie eats it all in one sitting, they start going for the seats - of course class President Kendall will not have them ruin school property, so they go for her instead... even Jackie, who seemed more adamant about eating Kendall than anyone else, despite not starving.
Played with in the Futurama episode "The Deep South", where after the ship is stuck at the bottom of the sea, Hermes holds up a brochure titled Code of Conduct for Cannibalism and attempts to suggest they eat Zoidberg.
In the Adventure Time episode "Mystery Dungeon", a motley band of Ooo citizens (Ice King, the Earl of Lemongrab, NEPTR, Tree Trunks, and Shelby the worm) are trapped in a dungeon. When it looks like the group is stuck in a dead end, Lemongrab is quick to ask the Ice King how he tastes, and tries to order him to "make yourself into food, immediately!" Fortunately, NEPTR points out an oven and some baking supplies in a corner of the room.
The Trope Namer is the Donner Party, a group of 1840s pioneers who took a shortcut that turned out to be a longcut, which left them in the position of trying to cross the Sierra Nevada mountain range during a very harsh winter: they got snowed in by October. While most everybody chose to wait it out, a party of messengers set out to seek help; they reached civilization in January. It took four rescue parties to evacuate the remaining survivors, the last of whom did not reach shelter until nearly May.
The case of R v. Dudley and Stephens, where three shipwrecked sailors in a lifeboat murdered a fourth, started eating him and were rescued less than a week later. It's often taught in law-related classes, both because it established the important historical precedent that necessity is not grounds for justifiable homicide and because the teachers probably figure that at least it's one case the students are sure to remember.
The other well-known case of cannibalism at sea occurred in one of the boats from the whale-hunter Essex (which was rammed and sunk by a whale; Melville didn't make that up!). After the survivors were rescued, the officers in charge of the boat went back to sea and had little difficulty filling their crews, which is usually taken as a sign that their actions were accepted as necessary.
Survivors of the Dutch ship Rooseboom, which was sunk by a Japanese submarine while carrying troops and civilians being evacuated from Singapore in February, 1942, may have resorted to cannibalism as they drifted for nearly 1,000 miles in an overcrowded lifeboat.
In fact resorting to cannibalism was prevalent enough that in England it was given the Unusual Euphemism of "The Custom of the Sea."
In Russia after Red October. It happened during the Siege of Leningrad, when Leningrad was cut off by the Germans in the fall of 1941 and the city was completely unprepared to spend a winter under siege. During the Russian Civil War, there were many reports of starving villages (their crops having been taken by the Red and White armies) eating their dead or even selling salted body parts.
It happened in the Ukraine during the horrific famine caused by Stalin's forced collectivization policy. By some accounts it was so common that signs were posted reading, "Eating Dead Children Is Barbaric".
Under Tsarist Russia, the Famine of 1601-1603 (partially caused by a volcanic eruption in Peru), and the Famine of 1891-1892 (caused by weather and Alexander III's incompentant and oppressive government), had this effect in some areas.
Allegedly happens during prison breaks. Hardened criminals, who intent to escape, would entice a green one to join them. There's a reason such tagalongs are called "porker".
Alferd (or Alfred) Packer was an incompetent mountain guide who ate the rest of his party when they became snowbound in the Rockies due to his bad organization. At his trial, the Judge lamented: "There were only seven Democrats in Hinsdale County and you ate five of them!"
The student canteen at the University of Colorado (Boulder) is the Alfred Packer Grill; motto: "Have a friend for lunch."
Believed to have been done by the doomed members of the Franklin Expedition, who got lost in the North. Borne out by the saw marks on the recovered bones.
Alexander Pearce, an Irish convict, was hanged in 1824 for cannibalism and murder, having eaten his comrades after they escaped from a Penal Colony in Van Diemen's Land (now Tasmania). Twice.
When the French frigate Medusa ran aground in 1816, the upperclass passengers were loaded into the lifeboats, while the remaining 150 sailors, traders and labourers were forced onto a makeshift raft. Fearful that the desperate survivors would slow them down, the lifeboat passengers soon cut the tow ropes and set the raft adrift in the open ocean. Violence, mayhem and cannibalism soon overran the helpless raft, and only 15 people survived to be rescued.
Defectors from North Korea have said that cannibalism was practiced during a 1996 famine. It's also been alleged to have happened during other periods of famine in the last several decades.
Believed to have happened to the native inhabitants of Rapa Nui (Easter Island).
In one famous shipwreck (name forgotten) several boats of survivors got away. The boat crew in best condition when they landed after several weeks without food didn't eat their dead comrade but cut him up and used him as bait to catch fresh fish. Those who ate them arrived much nearer death than the fish-eaters (who also gained by the fresh water contained in the fish flesh.)
Related in contemporary documents from the late phase of the Thirty Years' War, when famine affected wide regions of Germany. As described in C. V. Wedgwood's The Thirty Years' War:
"In Alsace the bodies of criminals were torn from the gallows and devoured; in the whole Rhineland they watched the graveyards against marauders who sold the flesh of the newly buried for food; at Zweibrucken a woman confessed to having eater her child. In Fulda and Coburg and near Frankfurt and the great refugee camp, men went in terror of being killed and eaten by those maddened by hunger."
There are many accounts of cannibalism in the Jamestown colony in Virginia during the "starving time" of 1609-10. Recently unearthed remains from the colony site of a 14-year-old girl whose body was butchered with knives and cleavers after her death reveal that the Jamestown colonists did indeed resort to cannibalism.
Canadian Thanksgiving is in celebration of the Frobisher Expedition coming back without having to resort to cannibalism.
