Bigfoot, Sasquatch, and Yeti

"Professor Farnsworth: Bunk! Bunk, I say! Bring me a bag full of Bigfoot's droppings or shut up!

Ranger Park: I have the droppings of someone who saw Bigfoot.

Professor Farnsworth: Shut up!"

- Futurama

The other UFO: Unidentifiable Furry Organisms.

Tall hairy humanoids who maintain a furtive existence in various remote corners of the world. "Bigfoot" and "Sasquatch" are different names for essentially the same entity, whose (ahem) stomping grounds are mostly in the northwestern corner of the United States and the southwestern corner of Canada. The "Yeti" or "Abominable Snowman" is a variety found high in the Himalayan Mountains, commonly depicted (whether due to associations with familiar Arctic animals like the polar bear, or just the "snowman" association) with white fur in fiction, although the local legends described it with red to brown hair. Other lesser known varieties turn up in world-wide folklore and history under an assortment of names, such as the "Skunk Ape" of the swamps of the southeastern United States.

Common characteristics are said to include an extreme shyness towards humans, emitting horrible odors and unearthly noises, and of course scattering large footprints about as they frolic in out-of-focus areas. Most scientific authorities regard these creatures as either entirely imaginary or the fabrications of human pranksters, but like lake monsters and the Chupacabra and unlike "out-and-out" fictional species such as the Wendigo or The Jersey Devil, BS&Y have devout believers in their existence. Often speculated to be akin to large, herbivorous hominids such as Gigantopithecus. More information on Bigfoot can be found at the Other Wiki.

Advertising
""Listen to the Yeti! Kellog's Pop-Tarts! You can freeze 'em, then eat 'em!""
 * "Jack Links" beef jerky has an ongoing commercial campaign centered around various humans deliberately annoying a Sasquatch and invariably getting attacked as a result.
 * A previous series of commercials for Pop-Tarts featured a yeti explaining how placing Pop-Tarts in the freezer made for a good summertime snack. Then the humans he was talking to would scream in fright, and then he would do the same. Example here.


 * Also the Tab Clear ad, in which the Sasquatch is revealed to be Kaiser Wilhelm II, fallen from his zeppelin into the mud of Oregon. Suddenly everything is clear...
 * A brand of iced coffee used Bigfoot for advertisements on TV and radio. One such ad mentioned that most witnesses saw Bigfoot between the hours of midnight to 3 am -- either because Bigfoot was raiding store fridges at night looking for iced coffee, or because most of the witnesses were drunk.
 * Kokanee beer commercials used to feature the sasquatch as a mascot.

Anime and Manga

 * In Ranma One Half the character of Pantyhose Tarou fell into the magic Spring of the "Drowned Yeti, Riding a Bull and Carrying a Crane and an Eel" (don't ask us how that happened). It resulted in his transformation essentially being a shaggy Minotaur with an eel for a tail and crane wings. Later, he splashed water from the Spring of Drowned Octopus (again, don't ask us!) across his back and gained Combat Tentacles.

Comedy
""I think Bigfoot is blurry, that's the problem. It's not the photographer's fault. Bigfoot is blurry... and that's extra scary to me. Because there's a large, out-of-focus monster... roaming the countryside.""
 * Comedian Mitch Hedberg lampshaded the fact that photographers always seem to end up having blurry photographs of Bigfoot.

 * Marvel Comics Alpha Flight features a team member called Sasquatch, who is more-or-less the legendary beast.
 * Originally, he was a scientist who got hit by gamma radiation, just like the Incredible Hulk, but got orange fur instead of green skin. A later retcon said he had inadvertently opened a gateway to the Realm of Great Beasts, giving him the power of a (fictional) First Nations demon.
 * And even more recently a small tribe of "actual" Sasquatches (Sasquatchii?) have been discovered, with the largest male being mistaken for a mindwiped Sasquatch (the superhero) and actually joining the team for a short time (until his ).

They come across a massive metal structure that had been there for hundreds of years, and Indy goes inside and sees the remains of a human: Han Solo. Han and Chewie had flown the Falcon into a wormhole and crash landed on Earth. Han was killed by Native Americans while Chewie survived and raged at them, creating legends of a massive furry ape-man. Indy notes an eerie feeling of deja vu when encountering Han's final resting place and he decides to stop the hunt for Sasquatch.

 * Also from the 70's is the classically bad film Snowbeast, about a Bigfoot/Yeti/whatever eating pretty young women at a Colorado ski resort until he gets stabbed to death with a ski pole by Bo Svenson. Read more here: http://en.wikipedia.org/wiki/Snowbeast
 * Harry and The Hendersons is about an American family who hits a Sasquatch with their car and brings him home. It was later a short-lived TV series.

 * Of note is Abominable, a.k.a. Rear Window with ABOMINABLE SNOWMEN!
 * They often feature Lance Henriksen in them
 * The Mummy Trilogy: Tomb of the Dragon Emperor includes a sequence with heroic Yetis. They look more like humanoid cats. Word of God is that their design was based on snow leopards and polar bears, in order to give something more exotic than more typical depictions.
 * A really strange movie called They Call Him Sasquatch features a group of unlikely people going to hunt for the aforementioned lifeform. No, they do not parody the theme from Flipper.

 * Clawed the Legend of Sasquatch features a Noble Demon sasquatch.

Literature

 * Lamb features a Yeti who is the Last of His Kind.
 * In the Discworld novel Thief of Time, our heroes encounter a yeti. It's a kind of troll, with thick fur. Since trolls are made of rock, this is hinted to be the insulating material stone-wool. Yetis are hunted for their huge feet and hands, and as a result, they evolved the ability to save their progress to load it should they die, which the met yeti demonstrates by being beheaded. To date, they went extinct thrice.
 * Yetis also appear in Moving Pictures, where they lie down in the snow (camouflaged by their fur) and jump out at travellers. If the ones that encounter the thousand elephants making their way across the mountains have the Reset Button ability, it doesn't get mentioned. Maybe they were overwhelmed by the awesomeness of the scene.
 * Harry Dresden encounters Yeti-like creatures in Proven Guilty after storming Arctis Tor.
 * A ski-simulation attraction at Dream Park included a cute fluffy baby yeti as an obstacle to be avoided.
 * One of the engineered future hominid species in Dougal Dixon's Man After Man resembles a yeti, and some of its descendants evolve into bigfoot-like variations.
 * The Long Walk (Where Slavomir Ravisz escapes from a Gulag), contains an encounter with a Yeti. In fact, that's why he got in contact with a publisher in the first place.
 * The Aquiliad by S.P. Somtow is a wacky Alternate History in which The Roman Empire has developed steamships and is now exploring and settling Terra Nova (i.e., North America). Where the narrator finds the Sasquatii, or, as the scholars put it in proper Greek, the Megapodes -- who greet the Romans with, "Shalom." Yes, the Sasquatii are descendants of the Lost Tribes of Israel, kidnapped and mutated by a Time Traveling Mad Scientist ... and it goes on to get even weirder.
 * The Yetis of the Harry Potter universe are given an entry in Fantastic Beasts and Where To Find Them. They're said to grow close to fifteen feet tall, have snow white fur, eat anything it comes across, live in Tibet, fear fire, and possibly are related to Trolls (Though no one has gotten close enough to one to actually study it).
 * In the Geronimo Stilton book I'm Too Fond of My Fur!, the title character goes off to find his friend Professor Von Volt in the Himalayas, and encounters a family of yetis.
 * In American Psycho, Unreliable Narrator Patrick Bateman claims that he saw Bigfoot on his favorite talk show and found him "surprisingly articulate and charming".
 * In the Robert E Howard story "Three Bladed Doom", the hero, El Borak, encounters and kills a yeti. Weirdly it's both a kill-crazy monster and a vegetarian. Also Conan the Barbarian has a couple of encounters with "grey apes" that are identical to the yeti in "Three Bladed Doom".
 * In Paul J. McAuley's Red Dust yetis are a genetically engineered combination of human and animal DNA created by the early Tibetan colonists when they came to Mars. The only one actually encountered, named Monkey is intelligent but mute.
 * The sasquatch is mentioned in Trixie Belden and the Mystery of the Sasquatch, when the gang are camping in Idaho. There have been several reported sightings, but all of Trixie's encounters turn out to be a man in a snowsuit.
 * There's a gag in one of the Nightside novels, in which a yeti-foot umbrella stand is one of the items on offer at a supernatural auction. Before the selling gets started, a pissed-off yeti stomps into the hall, marches up to the displays, scoops up the umbrella stand, shoots a really nasty look at the auctioneers, and stomps out.
 * The Goosebumps series had "The Abominable Snowman of Pasadena".
 * The Icemen of the Codex Alera are not Yetis, but are largely analogous to them, being furry, bulky, apelike humanoids who live in the far north and all. They're not normally aggressive, but they are powerfully empathic- picking up on humans' initial wariness of them and transmitting it back magnified ended up resulting in centuries of literally meaningless war between the two races.
 * One of the stories in Haunted 2005, by Chuck Palahniuk, is titled "Missing Link" and postulates that these creatures are actually humans with an odd genetic quirk causing were-creature-style transformation. The teller of this story belongs to a fictitious Native American tribe in which this trait is allegedly quite common, including a supposed case in the teller's own family.

Live Action TV

 * Bigfoot "guest starred" in more than one episode of The Six Million Dollar Man.
 * This Bigfoot was actually a robot built by aliens hiding in the woods to scare people away.
 * Bigfoot and Wildboy was a recurring segment in the 1970s children's program The Krofft Supershow, and a Spin-Off from the season it made friends with Steve Austin.

 * In perhaps the ultimate aversion of this trope, The X-Files -- a show which incorporated everything from human-alien hybrids to demonic possession to half-human half-tapeworms, and was filmed for half its run in Vancouver -- never once did an episode on Bigfoot.
 * In the official licensed comic book, there was one Bigfoot story. I recall the infamous "Jose Chung's From Outer Space" episode did feature Mulder watching the Patterson footage of an alleged female sasquatch.
 * He also watches it at the end of "The Jersey Devil", an early episode where, after a long pursuit of what the main characters fantasize to be a cannibalistic primitive hominoid that lives in the woods of New Jersey the creature turns out to be a perfect normal (and quite sexy) nude woman. Since she is killed also, there is no final answer to why she did behave that way, however.
 * In The Invisible Man, the invisibility gland was taken from the Sasquatch who had developed it in order to hide in the forest of America. To be fair, the main character was pretty shocked at this revelation as well. He was even more shocked when they informed him that the gland was from a female, which is why the MALE Sasquatch in the episode was so...affectionate.
 * In The Mighty Boosh, there is a tribe of female yeti that live in the woods in England. The episode's plotline is just a Distaff Counterpart version of the original yeti myth.
 * Here Come The Brides featured a Bigfoot hoaxer.
 * Bigfoot and other North American fuzzy walkers appear in several episodes of Lost Tapes.
 * "Big Guy" of Sanctuary is of the Bigfoot abnormal classification.
 * The Goodies did an episode spoofing Arthur C. Clarke (Creator)'s Mysterious World. Tim Brooke-Taylor & Co go into the Canadian Rockies in search of mysterious creatures, only to find that Graham Garden is faking their existence (including the inevitable spoof on the Patterson-Gimlin Film, which is given away by the zipper that Graham has to undo to take a piss). Eventually one of Tim's feet swells up to enormous size due to him constantly walking around steep slopes, and he has to flee into the wild (wearing a furry coat to keep himself warm) to prevent everyone who sees him laughing themselves to death over the sight of his Big Foot.
 * Humourously averted in Supernatural. While the existence of many supernatural and paranormal creatures is never questioned, Bigfoot is stated outright to be a legend. In the one episode where they start to suspect they've found Bigfoot it actually turns out to be a giant Teddy Bear created by a cursed wishing well.
 * Norg, The Scrappy of Power Rangers Operation Overdrive is a hilariously inept Yeti, whose one shining moment was being unwittingly spotted by the heroes while walking in a manner very similar to the Patterson film (se Real Life below).
 * The 1970's paranormal series In Search Of had an episode dedicated to the real life legend of Bigfoot.
 * An episode of the HBO Tenacious D show has the guys meet and sing a song about Sasquatch, which references the episode of In Search Of featuring him. They try to bring him on as their drummer, but he's terrible, so they let him down gently, telling him that they're not ready to be a "power trio." John C. Reilly plays the Sasquatch.
 * One episode of MacGyver featured a Sasquatch that turned out to be a guy in a rubber suit... or did it?
 * Animal Planet's Finding Bigfoot series.

 * Bigfoot appears in an episode of Futurama; the episode ends with a parody/homage to the Patterson film mentioned above.

 * When Peter drives into the TV satellite dish on Family Guy, he tells the angry mob Look Behind You because he saw Bigfoot. Bigfoot then explains this is about Peter, not himself.

Real Life

 * Tracks of supposed sasquatches are often found, which are sometimes revealed to be the work of pranksters when proper investigation is done, although some of them have been found to be possibly real.
 * The most famous Sasquatch video evidence is the "Patterson-Gimlin Film", which indisputably depicts either a Sasquatch or a man in a hairy suit. The footage as of 2010 still hasn't been proven or disproved.
 * Starting in the early 2000's a man named Phillip Morris came out as saying he was involved in the creation of a gorilla suit and communicating with Patterson as to how to broaden the shoulders and extend the length of the arms. Bob Heironimus who can be seen in the second part of the reel accompanying the documentarians would later claim that he was paid $1000 to wear such a suit and that he was the creature in the film. The involvement of Ray Wallace, the well known Bigfoot hoaxist has also been corroborated by his family after his death. The Other Wiki has more http://en.wikipedia.org/wiki/Patterson-Gimlin_film
 * However, Morris and Heironimus' stories do not match up, suggesting that at least one of them is lying or misremembering.
 * The Weekly World News was a supermarket tabloid which often ran Bigfoot stories.
 * However, in their case, it was pretty obviously satire. The Weekly World News was like that.
 * Some apes, such as gorillas, were known only as legends of "hairy wild men" until properly discovered.
 * Interestingly, the word "gorilla" first time appears in the writings of Carthaginian explorer Hanno, in an area that doesn't seem to have ever had any great apes. Some historians believe that Hanno and his men mistakenly killed and skinned some pygmies they thought to match the description.
 * Paleontologists have discovered species of extinct giant, herbivorous apes that bear a striking resemblance to Yeti. This may be the source of the legend.
 * It is speculated that ancient humans may have discovered or encountered such remains, just like the ancient Greeks misinterpreted elephant skulls for Cyclops. (Northern European Troll legends may be based on similar prehistoric encounters, which didn't end well for the Neanderthals).
 * Sometimes people record alleged vocalizations of Bigfoot like these.
 * I believe hearing that though it has not been proven to exist, Sasquatch is actually a protected species in Washington state. In other words; we don't know if it exists but if you see one don't shoot!
