Later, Ieyasu meets her minion Hanzo and thanks her for the great special effects and using the fake samurai ghosts to stoke Nobunaga's ego so she will fall into her plan.

Though a little unnerved, Ieyasu shrugs it off, since the real ghosts helped her manipulate Nobunaga anyway.

The contents were items they all needed yet they hadn't told anyone as much. Further investigation revealed hoof-prints and an inexplicable sled-runner trail in the snow.
- There's a Donald Duck story where Donald and Daisy have to seek shelter at a spooky castle whose owner turns out to be a vampire. This is revealed to be part of an elaborate commercial that was being shot at the castle, but when Donald asks him how he managed all those crazy "tricks" for the camera like floating in mid-air, the count states that they weren't tricks.

- Lake of the Dead: This Norwegian thriller revolves around a group of friends trying to solve an ancient mystery that involves an immortal crow leaving its feathers as calling cards. In the end a natural explanation has been found, but there is some disagreement about its feasibility. The protagonist insists that the solution is acceptable and nothing supernatural is involved, and to punctuate his words he picks up something from the table and waves it around...
Bernhard: Hey, where did this come from? It's a crow's feather...
- Live and Let Die, in what's probably the only appearance of the occult in the James Bond series, ends with Baron Samedi appearing at the front of the train Bond is in, laughing as usual, even though he was subjected to a coffin full of (presumably) venomous snakes earlier in the film.

- The Invisible Dog brings The Three Investigators to an old church rumored to be haunted by a "phantom priest" who carries a candle.

It will turn out to be some old man faking it, right? Nope; come the end of the book, the only part of the mystery left unsolved is...who is the phantom priest?

Lillis: Mama told me.
- In The Vampire Affair, a Man From U.N.C.L.E. novel by David McDaniel, Solo and Kuryakin spend most of the book in an Eastern European country battling what seems to be a vampire.

It transpires the department store Santa was the real Santa after all.
- In the Baywatch episode "Strangers Among Us", a group of half-crazy UFO believers cause problems for the lifeguards as they misinterpret water phenomena on the beach as signs of aliens and almost drown and so on. They are led by the more sensible Dr. Faye Taylor, who has a more scientific view on UFOs. All seems to be normal until the very last minutes of the episode, where she disappears without a trace during something resembling a strange weather phenomenon.
- In one episode, a person is found dead in the middle of nowhere by a ufologist. At the end of the episode, Brennan and Booth manage to find the real killer. They are lying on the hood of a car in a field, stargazing and talking about whether or not aliens are real. Just then, all the crickets and other natural sounds disappear, leaving both of them a little freaked out in complete silence.
- In another, a murderer uses a myth about a witch in the woods (an intentional parody of The Blair Witch Project) to cover up the unintentional killing of his filmmaker brother. At the end though, Angela and Hodgins see what appears to be a real ghost on footage of the murder. They promptly decide to never mention it again.
- Castle has quite a number episodes that pit Castle's child-like belief in the supernatural against Beckett's rational skepticism but most of them usually go for the Maybe Magic, Maybe Mundane ending. However, there are two notable exceptions:
- In the 6th season episode "Time Will Tell," an episode about (gasp) time travel, Beckett spills her coffee on a letter that had been a key piece of evidence in the case after the case is over. The murderer had been using a stained copy of that letter to try to track down an intended victim but the cops had used the pristine original to find him first. The stain Beckett made that afternoon matched the one on the murderer's copy even though his copy predated the spill of the coffee. The incident is not really "in your face" proof, but it is chilling because the only possible explanations are "time travel" or "1 in a million coincidence."
- But the 7th season episode "Clear and Present Danger" takes the cake for playing this trope straight as an arrow when it turns out that the victim really was killed by "the invisible man." (Well, an invisible woman). A scientist working for a shadowy government agency made a breakthrough and had created a functional invisibility suit which was then, in an ironic twist, used to murder him. Beckett adjusted reasonably quickly to the reality of invisible people walking about and Castle's paranoia and creation of an "invisible man trap" suddenly seemed unusually reasonable.
- British medical soap/drama Casualty pulls this one once. In one episode Tom Baker plays a patient who claims he's an alien; the nurse treating him believes he's delusional until a power cut knocks out the lights and he's shocked at the sight of the patient's glowing green eyes.
- Doctor Who:
- "The Abominable Snowmen": An explorer looking for yeti in the Himalayas runs afoul of some yeti that are actually robots controlled by an Eldritch Abomination. At the end, as the explorer is saying farewell to the Doctor, a real yeti appears.
- In "Robot of Sherwood", Clara has the Doctor take her to the time where Robin Hood existed, despite the Doctor saying that Robin Hood was merely a legend. Deciding to prove it, the Doctor took her to the era...and came face to face with Robin Hood. Throughout the remainder of the episode, the Doctor tried to find proof that Robin Hood wasn't real. Upon learning of the presence of robots, the Doctor became convinced that they used the legend of Robin Hood to create a Hope Bringer for the peasants as part of their ruse...until the Sheriff pointed out the impracticalness of creating an enemy that could ruin their plans. Upon learning that the future would believe he was only a myth, Robin was okay with that.
- In one episode of Don't Eat the Neighbours, Lucy ends up depressed after she learns that Old Father Bunny has not delivered the bicycle she wanted. So that night, the other adult male characters in the show get up onto the roof, each claiming to Lucy that they are Old Father Bunny and they have brought her the bike she wanted. The next morning Lucy has 7 bikes, but there were only 6 men up on the roof last night. She then finds a note attached to it from Old Father Bunny apologizing that it is a day late, but he and his elves were busy painting it into a multicolour one.
- Eerie Indiana, "Marshall's Theory of Believability": A visiting paranormalist turns out to be running a UFO scam. After this is revealed, the scammer's accomplice shows up and it's revealed that the alien artifact people have been fighting over all episode isn't one the accomplice planted — upon which it starts glowing and flies away.
- Family Matters did the Santa version in "Miracle on Elm Street", with Carl getting a space helmet he had wished for as a kid.
- In an episode of Gilligan's Island, on the first Christmas Eve they're stuck on the island, the Skipper shows up dressed as Santa Claus. He happily tells the castaways that they should be thankful that they are on an island with food and water, that they all get along with each other, etc. "Santa" then leaves into the jungle. An instant later, the Skipper, dressed normally, emerges — from the opposite direction — out the jungle, carrying the firewood that he went to get a moment ago. Even the professor was puzzled by this one.
- The Golden Girls liked this trope.
- In one episode, Rose thinks she sees a UFO overhead, and even Dorothy is convinced when the U.S. Air Force confirms it. At the end of the episode, Sophia reveals that the "spaceship" was just an experimental aircraft that the military didn't want anyone knowing about. When Dorothy goes out to break the news to Rose, the two sit for a while on the lanai, and Dorothy drops off to sleep...just in time to miss the sky suddenly flood with light and sound. Rose sits back in her chair and smiles, convinced that she's seen the real thing.
- In a non-supernatural example, Sophia, who's been struggling with memory issues, clings to the fact that her late husband carved a big heart that read "SAL LOVES SOPHIA" on the pantry door in their apartment in Brooklyn. When Dorothy and Sophia visit, they find the Petrillo family height chart instead, which deeply upsets her. However, at the end of the episode—and after a visit from a ghostly version of Sal himself—Sophia discovers the heart in question on the door of the bedroom closet.
- Both Blanche and Sophia have ghostly visitations in a Season 7 episode. Blanche insists that she hears the voice of her dead grandmother in her old room at the family plantation, which is set to be torn down; at the end of the episode, a set of wind chimes Blanche took from the room swings in the breeze, suggesting that Blanche is right. Meanwhile, Sophia has a near-death experience and talks with Sal in Heaven, only to be revived. When Dorothy tries to explain this away as a hallucination brought on by lack of oxygen, Sophia teasingly calls her "Spumoni Face," a nickname which Sal told her about while she was temporarily deceased. Dorothy's shocked—she's never told her mother about that nickname...
- The Greatest American Hero, "The Devil and the Deep Blue Sea": The missing boats aren't due to the legendary sea monster "Carrie", but to pirates. The real sea monster appears at the end of the episode.
- The Hardy Boys/Nancy Drew Mysteries:
- "Hardy Boys and Nancy Drew Meet Dracula": In the episode, the Hardy Boys suspect a man of being Dracula, but this is apparently dis-proven. At the end, the villain is in handcuffs and standing in front of a mirror, and Joe Hardy notices that the villain has no reflection, while the other characters conveniently not look at the mirror. The villain is taken away by the cops before Joe can get anyone else to notice.
- "House on Possessed Hill": The Hardy Boys have supposedly dis-proven a haunted house. Final scene is the brothers driving by the house in their van; Frank is giving logical common-sense explanations for all the haunted phenomena. Cue Joe looking towards the house just as they drive away, in time to see a ghostly figure walk out of the house...which disappears when Frank stops the van to look.
- Home Improvement:
- Played for laughs in an episode, complete with The X-Files-parodying dream sequence. The episode starts out with Tim mocking Wilson for believing he'd been visited by aliens. The end implies that Michael Jordan, Dennis Rodman, and several other NBA players are, in fact, aliens—with "bluish-gray" immigrant cards.
- Wilson visited Mark as Santa Claus when he was told that Santa does not exist—or at least this was what Tim and Jill thought, as the REAL Wilson was revealed to be in his garden the whole time Santa was visiting.
- An episode of Hustle has the con artists tricking a corrupt tabloid publisher into believing that the Queen Mother was killed in World War II and an actress was hired to keep up public morale. It works and the team laughs at how the publisher could believe such a crazy story. However, the final shot of the episode shows what is quite clearly Queen Elizabeth II placing flowers on the grave of that "actress."
- JAG: In an episode, a father kidnaps his son while he has him for weekend visitation because he is convinced the boy is the reincarnation of his old war buddy and has to take him to their cabin one last time. The episode consists of Harm trying to find him and convince him to turn himself in while authorities are also chasing them. The episode ends with Harm sitting on the porch step with the father and son, and the boy turns to them with a smile and thumbs up while flashing briefly into the form of the father's friend. Both of them see it, though the kid doesn't seem to be aware.
- An episode of Jonas revolved around the ghost of a volunteer fire fighter who swore he would return from the grave so that he could once again "volunteerily [sic] fight fires." He also loved chili and plaid socks. After the episode, we see Joe sitting in a chair narrating, like Kevin had been doing for most of the episode. The two start arguing about which has a better evil laugh, when they suddenly hear another evil laugh, and run. Turns out it was Nick, who was using a voice changer. He tells us there's no such thing as ghost, winks at us then leaves....and we hear the laugh again, and see a nearby bowl of chili get emptied after a voice says "oh, chili".
- C.J. Lamb on L.A. Law was representing a home owner who claimed his house was haunted. She got her assistant to make the lights in the house go out and on, freaking out the jury when they visited the house. When C.J. and her assistant are outside, the lights in the house start going on and off on their own, causing the two to run away themselves.
- Lois & Clark: A Christmas episode sees Superman pull a Santa-suited Perry White around in a sleigh to distribute presents to children on Christmas Eve. Later, as Lois and Clark leave the Daily Planet, they hear sleigh bells and a jolly "Ho Ho Ho!" from high above, and Lois exasperatedly comments that Superman must still be dragging Perry around in the sleigh—unaware, of course, that Superman is actually standing right beside her...
- I Love Lucy: The four adults each separately decide to dress up as Santa to amuse Little Ricky. But when they gather together in the kitchen afterward, who is the FIFTH Santa? The one who vanishes into thin air?
- The Lucky Luke Live-Action Adaptation had an episode about a fake ghost train that used the "helpful person was dead all along" variant.
- In the episode "Ghost Ship", MacGyver reveals that the monster is just a man in a suit and a prerecorded monstrous roar. At the end, MacGyver and Pete hear the exact same roar from somewhere out in the wilderness while they're looking at the stereo that isn't currently playing the tape.
- "The Visitor": after Mac exposes a couple of con artists claiming to be aliens to exploit a cancer patient and her husband, the oddball vacuum cleaner salesman that helped him suddenly disappears. He and the sheriff then see a UFO taking off...
- In the Martin Halloween episode "The Night He Came Home," Martin's friends set up an elaborate haunting hoax based around a ghost story involving the former tenant of his apartment. Naturally, after the joke is played and he kicks them out, he begins to relax with Gina. The two become so wrapped up in each other, they just miss the real ghost lumbering across the room and shutting off the lights on his way out.
- Matt Houston had the titular detective abducted by real aliens in an episode where he's investigating a (fake) claim of abduction covering up a murder. Of course, he doesn't remember, no one else sees it, and the abduction has no relevance to the rest of the plot at all.
- Midsomer Murders:
- In one episode, the villains organize a series of 'ghostly' appearances in order to try and drive their victim insane. Right at the end, after the hoax is revealed and all the characters have left the room, we see an empty rocking chair creaking back and forth...
- Another starts off when Barnaby's wife thinks she ran over someone crossing a road next to an old asylum, but can't find the body. At the end of the episode, Barnaby himself does the same, but where the previous one was explained by the presence of a door near the road, the door here had been walled off...
- The Munsters, "If a Martian Answers, Hang Up": Herman thinks he's contacted aliens on his radio, but actually it's just a couple of kids playing a game. The alien costume they used at the end was originally seen in The Outer Limits.
- Murdoch Mysteries:
- In "The Curse Of Beaton Manor" Murdoch scolds George that voodoo is not real. It is revealed that Timothy Beaton used pufferfish poison (from Haitian voodoo) to induce a near-death state and thus 'come back' from the dead. At the end of the episode the final Beaton suffers a fatal heart-attack from being pierced by a Voodoo Doll.
- The Holy Grail in "Murdoch and the Temple of Death" is strongly implied to be the real thing. The killer jumps off a 60-foot cliff thinking it will save him, despite Murdoch telling the man to stop, and as Murdoch looks down on the man's corpse, a thunderclap sounds (seemingly in daylight) and Murdoch reacts to it. Later, Dr. Iris Bajali steals it from the station house and flees with Murdoch in pursuit; he tells her it belongs to God, and when she shouts back, "There is no God," she is struck by lightning and dies. Later still, a museum staffer accidentally knocks it over and disposes of the clay outer layer, leaving a metal chalice standing on the shelf that appears bathed in a (heavenly?) shaft of light.
- My Hero: George is dismayed by the increasing discontent at Janet's Christmas Day party, so he asks all the guests what they'd like. Dr. Crispin is dismissive, but the others answer honestly. He flies out, bringing in a man in a Santa costume (who complains about being very tired)... but just as the guests mock his charade, the man gives them all exactly what they asked for. At the end, Janet wonders how the man got the requested items, and George answers, "I'm glad he decided to help. Normally he sleeps all day today."
- Night Court:
- In the first season Christmas Episode "Santa Goes Downtown", a man that Harry Stone takes for a street corner Santa turns to be the real thing.
- Another Christmas Episode has Buddy handing out presents that were picked out by "his friend Nick". At the end he gives a present to the episode's antagonist, a man he'd never met before, and it turns out to be a specific yo-yo he had asked for as a child but never gotten. The cast is quick to be freaked out by it and wonder if "Nick" is Saint Nicolas a.k.a. Santa.
- Quantum Leap:
- "A Portrait for Troian". Sam finds himself helping a young woman who seems to be haunted by the ghost of her late husband. The haunting turns out to be a hoax staged by her brother to drive her to suicide, but at least one member of the episode's supporting cast turns out to be an actual ghost.
- Another was about a mummy's curse being faked. It ended with the mummy strangling the hoaxer.
- Yet another episode involved a creepy castle with several characters, including the one Sam leaps into, believing themselves to be vampires. One of them gets zapped by lightning, after which Sam triumphantly takes off the dead guy's fake vampire teeth. Just before leaping, he looks into a metallic tray and doesn't see his own reflection. The previous episode ended with Dr. Ruth being replaced in the waiting room by a man with vampire fangs. It doesn't seem likely that fake teeth would be transported there.
- Don't forget the episode where a Yeti helped rescue someone, and they only see it at the very end, IIRC.
- This was always the ultimate joke in the "Penelope" sketches on Saturday Night Live. Kristen Wiig plays the titular character, a passive-aggressive young woman who constantly one-ups everyone around her: if someone is going through a divorce, then she just divorced her husband in the hallway; if someone claims to be the inspiration for The Curious Case of Benjamin Button, then she's actually aging in reverse right now. The sketches would end with Penelope making a truly outlandish claim, such as an ability to shrink or being best friends with Liza Minnelli and a tomato, and everyone getting so angry that they storm away. After they left, that final claim would come true (Penelope shrinking down as she took a phone call, or Liza herself—carrying the tomato—bursting through the door and declaring that she wanted to have a girls' night out). It's unclear if all of Penelope's crazy stories were real, though.
- In the Smallville episode "Lexmas", Clark uses his Super Speed to deliver presents to the children of Metropolis. Along the way, he meets a drunk man in a Santa suit and saves him when he falls off a roof. After a talk where Clark reveals he sacrificed his original plans for the day to deliver the presents, the man decides that the Christmas spirit isn't dead after all and departs. Later, the man comes to Chloe, who's looking after the last of the gifts until Clark gets to them, and says he will deliver them to pay Clark back for saving him. After Chloe gives him the last children's addresses, the man pulls a Stealth Hi/Bye, taking the huge pile of gifts (big enough to fill the room and reach the ceiling) with him.
- At the end of the fifth season of Stargate SG-1, a "malfunction in the ventilation systems" is implied to be Daniel Jackson looking after his old team.
- An episode of The Suite Life of Zack and Cody revolved around a haunted hotel room. They decide to spend the night in it, and weird stuff, including everyone but Zack disappearing, starts happening. Turns out it was all a prank to get back at Zack for the pranks he pulls. Later Zack and Cody go back to get Cody's blanket, and a woman (whose portrait is in the room) walks up to them and hands them the blanket. After they thank her, she walks into the portrait. The episode ends with Zack and Cody running and screaming. Interestingly, the portrait did come to life and speak to Zack while the prank was going on (she even said "they're out to get you", in retrospect a warning that it was a prank by his friends), but Zack never brings this up while they're explaining the hoax to him.
- In an episode of Taggart the team are investigating a series of murders centering round an alleged medium. The medium claims to DCI Jardine that he is receiving messages for him from the late Jim Taggart and backs this claim up with a number of facts only someone who knew Taggart could know. Later on Jardine discovers that Taggart actually investigated a crime involving the medium. When confronted with this, the medium agrees but says that in fact he never met Taggart himself.
- A non-supernatural example from That's So Raven. Raven has a vision that the high school's new janitor is "undercover," and guesses that he's actually a scout from "Undercover Superstar," a Show Within a Show that uses spies to discover talented teens. This leads to all of the main characters performing elaborate production numbers for the janitor...who turns out to be "undercover" in the sense that he's secretly searching the school for insects. After the truth comes out, another janitor approaches Raven and asks if anyone in the school is interested in music. Raven, who's sick of the whole idea by now, leaves...and misses the janitor removing "his" disguise and revealing herself to be Paula Abdul, who's working for "Undercover Superstar."
- The Twilight Zone:
- In "The Monsters are Due on Maple Street", a town goes into a panic when they come to believe that aliens have landed nearby and that someone on their street might be helping them. It turns out to be mass hysteria— induced by the actual aliens, who want to turn the humans against each other by having them chase imaginary aliens. Tricky.
- In "Nightmare At 20,000 Feet", a man who spent six months in an asylum is on a flight back home when he sees a strange creature on the wing of the plane. He becomes especially distressed when it begins tearing at the plane's engines, but every time he tries to tell someone, the creature disappears. After he steals a police officer's gun and opens the emergency exit to kill it, it gets him sent back to the asylum. However, as he's being carted off, the camera pans to reveal the damage the creature did to the wing.
- One episode of Two and a Half Men has Charlie experimenting with marijuana. He ends up having hallucinations of his ex-girlfriends (and ZZ Top). After he makes a date with Rose, it's revealed she's the only one who's real.

- In Veronica Mars it is clear that our titular heroine's dreams and conversations with her dead friend Lilly are happening in her head, and after Lilly's murder is solved they stop. However the second season episode 'Normal is the Watchword' has Lilly briefly appear and save Veronica's live by distracting her at a key moment—the implication being that her (Lilly's) ghost intervened directly.
- Walker, Texas Ranger season 3 episode "Case Closed" was about an alleged government cover-up of an UFO several decades ago. A few unreliable accounts and an unfruitful search lead to nothing more than an empty chamber where it seemed the government had created a living environment for this so-called alien, which is empty. The episode then rolls into the average fight scene at the climax of the story like all others, and has a fairly mellow ending... until an old tape is found that was supposed to be destroyed by the government, and it shows evidence of a real alien being discovered, though only a hand to maintain some realism and avoid dipping into science fiction.
- There's a non-supernatural variation in Weeds. Shane claims he saw a mountain lion and shot it with a BB gun, but when Nancy finds out the neighbor's cat has disappeared, she finds the timing suspicious and thinks Shane's imagination has got the better of him. Shane insists he knows the difference between a mountain lion and a cat, but Nancy is unconvinced. Then at the end of the episode, she steps outside and finds herself face to face with a very real mountain lion.
- A Halloween Episode of Wishbone had an appropriately mild example. Joe is scared of a haunted house because when he was a kid, he saw a pair of glowing eyes that left him scared since. Those same eyes are glimpsed stalking the main characters throughout the episode. At the end, they turned out to belong to a stray cat, leading Joe to believe that it was just a cat he saw all those years ago, ending his fear. However, after the kids leave, another pair of eyes appeared, just for us. Still cat-sized, though. (Oh my God, another cat).
- The X-Files, "Quagmire". Mulder and Scully investigate a lake where a Nessie-like monster is rumored to exist.

- Spoofed in I'm Sorry I'll Read That Again, when Tim has been telling the others a ghost story, and towards the end exaggerates it severely to give them a fright. After they've all left, fed up, Tim finishes the story, chuckling slightly...only for the lights to turn off as he's confronted with an ethereal voice. After he's run off, this exchange occurs:
Bill: Hah-hah! Ah, you certainly frightened him off with that spooky voice, David.
David: It wasn't me, it was Graeme.
Graeme: I thought it was Bill.
Bill: ...No, it wasn't me.
Jo: Or me.
David: ...Well, if it wasn't any of us...it must have been... [dramatic music] ...somebody else!
- This happens in some versions of Ruby Moon. Two actors play all the characters throughout, then it's gradually revealed they are doing this in-universe, and are (at least partially) aware of it; the script implies their missing daughter never existed in the first place, and the dolls of her simply made them convince themelves she was real. Lights down, curtain... and then she is heard singing her ditty one last time.
- The play The Woman in Black plays with this. The premise of the play is that two men are acting out the events, aware that they are doing so (but unaware of the audience). In fact, there are three actors, one of whom plays the Woman in Black herself. Both 'actors' believe the other to have hired her as a surprise for the other, until the end. The pretense extends as far as not crediting the Woman in Black in the programme.
- In Arcanum: Of Steamworks & Magick Obscura, there's the Stillwater Giant. One main quest involving you tracking this thing down to get it to a person who can mark your next destination. It's normally hide in form of a blue rabbit, but when you captured one that's marked and sent for examination, it turns out to be a fake, but the guy still gives you the location to Qintarra. After finishing the quest and leaving the town, you will be pulled into an encounter with...a blue rabbit. Attacking it and it turns into the Stillwater Giant. It looks very much like the fake Stillwater Giant skin that the player can steal or purchase from a museum display.
- In Captain Morgane and the Golden Turtle, Morgane, on learning that Dinsdale thinks he's seen a ghost, successfully tricks him and his brother with a fake Bedsheet Ghost. However, she then finds out that Dinsdale's original ghost wasn't his imagination.

At the end, though, it all seems to be a hoax, but then again, who, or what was talking to one of the soldiers in on it at the end?
- The puppet in Five Nights at Freddy's 3 has both a Phantom state and a real form◊
- The whole plot of Odin Sphere: essentially, all events in the game are a collection of overarching storybooks read by a girl named Alice in the attic of her house. If players manage to unlock the path leading to the best ending of the game, Alice states how tragic the story ended until she notices one of the book's cover ornament resembling a Valentine coin. She takes it off and prays that the Pooka will find the coin, but reminds herself that it's just a story. Upon leaving the attic, a portal opens up and two Pooka come out to retrieve the coin, implied to be the last Valentine coin they are looking for that will undo the curse of the Pooka transformation, and leave a final book in its place. This indicates the current world is actually The Future set sometime after the events of Armageddon, which the last book details.
- In Professor Layton and the Unwound Future, time travel turns out to be real. "Celeste" is actually a time-displaced Claire, who was sent forward in time moments before the accident that claimed her life. The nature of the time travel means she gets forced back to the time and place she was sent from at some point.
- In the horror adventure game Scratches: Was everything that happened to James Blackwood the product of a curse? Or was it simply a misfortune that Blackwood in madness blamed to a cursed mask? If the curse was not real, then how to explain the first dream? The coda on the alternate ending describes a rational explanation for everything, however it mentions at the end that there is still something that doesn't fit while panning to the cursed mask.
- Irregular Webcomic!: A storyline in the "Steve and Terry" theme had Steve discovering that the monster in Loch Ness was actually Lovecraft's Cthulhu; after they leave, the story ends with a shot of a reptilian head emerging from the loch (and a Lampshade Hanging narration). A parody example, since the "it's not really a plesiosaur" explanation is actually considerably weirder than the standard Nessie.
- At the end of the "Big Haunted Battleship" storyline of Schlock Mercenary, it's pointed out by several characters that the "rational" explanation of the ghostly voices on the PDCL is so contrived that it's more rational just to accept it was haunted. This isn't a throwaway gag, either; Petey's inability either to accept or to deny the existence of ghosts is responsible for both his introduction and the PDCL's eventual destruction.
- This happens every now and then in stories from the Slender Man Mythos. Usually in the middle of it, as demonstrated in Seeking Truth/The Mystic.
- A video by Smosh titled "Bigfoot Is Gay" has the two main characters looking for Bigfoot after they are shown a video on the news showing footage of him.

Shortly after that, a real Bigfoot comes by.
- Aaahh!!! Real Monsters: One episode had the Power Trio trapped in a severely haunted house, the rub being that while monsters exist, ghosts do not (this is repeatedly stated by
HermioneOblina). It turned out that the house was the bunker/battle ground for a soldier monster who caused all of the strange happenings—except one. All four monsters quickly leave, and the house resumes all of its disturbing behavior.
- The Ace Ventura: Pet Detective Animated Adaptation, episode about "G.C." used the "helpful person was dead all along" variant.
- The 1992 The Addams Family cartoon had an episode called "Puttergeist", which revolved around the legend of a golfer ghost with a giant golf ball for a head appearing every Halloween. It initially turns out that the Puttergeist is nothing more than a publicity stunt performed by the Normanmeyer family for generations, but the very end of the episode shows that the Puttergeist actually exists.
- The Adventures of Jimmy Neutron:
- Subverted multiple times before being played straight in "Phantom of Retroville": The tale of a ghost at an amusement park is told, and Jimmy, being Jimmy, decided to disprove it. The first phantom encountered throughout the episode turns out to be Nick in a costume. Then another phantom shows up, but is quickly revealed to be Cindy and Libby, also in costume. Then another phantom shows up, this one having a sinister glow, and succeeds in scaring the kids into running away, but turns out to be Judy Neutron in a more elaborate costume, with the goal of scaring the kids for sneaking out at night in mind. Then, while she and Hugh have an argument about pie, a fourth phantom rises out of the ground, this one translucent and glowing purple, scaring the two away.
- Being a person of logic and science, Jimmy Neutron didn't believe in Santa Claus (it didn't help that he didn't get the present he wanted two years prior), but soon learns that there are some things that can't be proven with facts.
- In the Adventure Time episode "The Creeps", all the characters are seemingly killed one by one by an evil ghost.

A later episode returns to this and explains the nature and origins of the real ghost in detail.

He even becomes a background character from then on and even dons the "Bob" t-shirt from the flash card!
- In The Angry Beavers episode "Omega Beaver", Daggett becomes convinced of the existence of the Howler Leeches from a conspiracy comic book, eventually being attacked by a group. After it's revealed that the leeches were actually Norbert and their friends playing a trick on Daggett (following him siccing a vicious leech-killing dog on them), it's revealed to the viewers that the leeches are real.
- In the Season 3 episode of Avatar: The Last Airbender titled 'The Painted Lady', the heroes encounter a small fishing village that is dying out because of pollution caused by the Fire Nation. Shenanigans occur while Katara masquerades as the Painted Lady, the patron spirit of the river and the village, and saves the day despite her ploy coming to light. Valuable lessons are learned regarding honesty and hard work, and it appears that the Painted Lady exists only in the hearts and imaginations of the village. The end! Oh, except for the part where after all this, right before they leave, the REAL Painted Lady appears to Katara to thank her for all that she's done. This sort of makes sense since spirits are real, though mostly intangible, beings in the Avatar universe.
- In the episode "Grundy's Night" of The Batman, after Solomon Grundy is revealed to be Clayface in disguise, a real zombie hand reaches out of the swamp. Ooooh...
- Captain Pugwash once came up with the brilliant idea of using a fake sea serpent to scare the crews of other ships into running for the lifeboats so that he and his crew could rob them blind. (The Pirates Who Don't Do Anything, the crew of the Black Pig most assuredly were not!) Just after the grand scheme had gone hilariously pear-shaped in a way that Tom the cabin-boy couldn't get his boss out of, a real sea monster showed up and succeeded where the fake had failed.
- Code Lyoko has "Is Anybody Out There?" After the "ghost" is revealed to be a monster created by XANA, the episode ends with Sissi trying to summon the ghost after a Return to the Past. Sissi and her friends are scared off by a spooky voice, but it turns out to be Odd and Ulric playing a joke. But then they leave and we see the boiler door shut and hear a ghostly moan...
- Celebrity Deathmatch has "The Prophecy". Stacy finds what she believes is a prophecy foretelling that one of the Deathmatch staff dies tonight. Throughout the episode it looks at several points like one of them will bite it (Nick gets shocked by a faulty microphone, Stone Cold gets run over by a moose, Mills Lane almost spontaneously combusts, and finally a plane crashes into Johnny), but they all survive. At the end, Stacy admits that she made a mistake. Then she explodes, killing her.
- The Emperor's New School: Yzma used fake aliens in a failed attempt to become Empress and she constantly told Kronk aliens didn't exist. In the end, Kronk met real aliens but didn't believe it.

At that moment, the Great Potato shows up to save them, much to Wanda and Timmy's shock.
- When Barney Rubble sees a sea serpent in the The Flintstones, his response is to tell Fred "I was reading this article where this scientist says there's absolutely no proof for the existence of sea monsters". Fred says so what and Barney delivers a punch line of "So I wonder if that sea monster believes in scientists".
- At the end of Fun and Fancy Free, Mortimer Snerd is crying over Willie the Giant's Disney Villain Death. Edgar Bergen assures him that Willie didn't die because Willie wasn't real to begin with, that he was just a figment of Snerd's imagination. Then Willie lifts the roof of the house to peek in! Bergen faints dead away.
Willie: What got into him?
Mortimer: Oh, uh, just a fig-a-ma-tation of his imagination.

- In "Heatwave Holiday," Garfield, Jon, and Odie deal with the titular heatwave by setting up a Christmas display in the middle of July. Soon, everyone in town follows suit, and the group even exchanges presents—right before a news announcement reminds everyone that it's still, you know, July. That night, as Garfield sleeps, we hear sleigh bells; the fat cat wakes up and goes into the next room, where he speaks to someone just offscreen: "Oh, it's you...no, it's not Christmas. Sorry." Garfield goes back to bed and comments that of all people, "he should know better"—and a loud "HO HO HO!" is heard.
- Goober and the Ghost Chasers often featured the real ghost helping the gang against the fake ghost (sometimes the fake ghost is also pretending to be the real ghost).
- In the show Gravity Falls, this trope would appear a lot since it's a show about kids who look for supernatural weird stuff in a creepy town, but they usual find out it's real in the middle of the episode. The only exception is in the episode "The Legend of the Gobblewonker", where the titular sea serpent was revealed to be an automaton made by Old Man McGucket. But at the end, the camera shows the bottom of the lake, revealing a large sea serpent swimming around, making whale noises...
- Growing Up Creepie:

- "Haunted Train" was an episode where Arnold, Helga, and Gerald heard the story of a train that takes you straight to a "fiery underworld" with the ghost of the conductor who'd supposedly driven the original off the tracks and down into the underworld. The kids go check it out and sure enough a train shows up and takes them through a hellish scene, just like in the story. It turns out it was just an average train that passed through a steelworks. At the end the train races past with the ghost conductor sitting on the front, playing accordion and singing the urban legend.

Intrigued by the promise of treasure, Arnold, Gerald, and several of the supporting characters head out to the caves where instead of a ghost they come across two counterfeiters. They end up saved and the counterfeiters arrested while the scene ends with the sound of Wheezin' Ed's laughter echoing through the cave.
- "Ghost Bride" finds Gerald telling the story of a woman who, left on her wedding day by a groom in love with her sister, puts on her wedding dress, grabs an ax and kills both her ex-fiancee and sister before jumping out the window to her own death. Every year on the same day, the ghost of the bride returns to the cemetery looking for fresh victims, humming the wedding march the whole time.

When she hears barking she becomes mad, encouraging him to go dangerously fast, until a man with a golden hook for an arm causes him to swerve off the road, the scarf getting caught in the tree and taking his head off. When the boys go through the same park for ice cream later...they believe they're being chased by the cabbie who is eventually revealed to be Ernie, driving a carriage to earn more money. It ends with him being approached by the same woman, mourning the loss of her dog and offering him her scarf.
- In "Four-Eyed Jack" from season 2, Grandpa tells Arnold and Gerald a story about a mad scientist who lived in the boarding house and was killed by an experiment involving beans. Afterwards weird things start to happen that fit the tale. After the events are revealed to be coincidental to Grandpa and his secret bathroom, the boy's go to bed and Gerald wakes up to Four-Eyed Jack who halfheartedly scares him.
- Used as a Double Subversion in Jackie Chan Adventures, "The Chan Who Knew Too Much": Jackie tries to stop a villainous group of modern-day druids who believe Stonehenge is an ancient magical Weapon of Mass Destruction and intend to activate it; he dismisses their claim as a crackpot theory, along the same lines as people who think it's a landing beacon for UFOs. At the climax, they succeed... but nothing happens. Later, after the disappointed druids are arrested by Interpol, a UFO appears, drawn by the signal of the activation.
- Jem, "Mardi Gras": Jem and the group are invited to stay at a haunted hotel where there are strange things happening. People assume it's the ghost of a pirate that loved Lily Rose.

- Phineas and Ferb:
- "That's the Spirit" Lampshades and then subverts it. After discovering the haunted house was just a Halloween hoax, Phineas says "Isn't this the moment in one of these things when someone really turns into a ghost?". Spooky music plays, the camera focuses on the family behind the hoax for a moment before Russell just says "Dude that's it", and they wander off.
- In the original airing, this episode was followed by "The Curse of Candace", where Candace spends most of the episode thinking she's a vampire due to some of Phineas's and Ferb's preset experiments. At the very end, they clear up the misunderstanding, she takes off her cloak... and then she crumples into ashen dust. So in a way, this is a double subverted Brick Joke.

After the villain (unaffiliated to the hoaxers) is arrested, the gang sees pictures taken by a previously lost underwater camera taken at a much greater depth than the submarines could have operated at, which show flippers and other body parts of a completely different entity. As the gang drives off in the Mystery Machine, the real Loch Ness Monster briefly comes to the surface in the foreground before diving underwater again, unnoticed.
- The Simpsons:
- The eleventh "Treehouse of Horror" episode combines this with a parody of The Brady Bunch. Lisa and Bart, playing Hansel and Gretel, are captured by a witch, who claims she needs to get ready before her boyfriend comes over. She says that his name is "George Cauldron," a deliberate reference to Jan Brady saying she had a boyfriend named "George Glass" after seeing a drinking glass on her nightstand.

This confuses the Tick, who refuses to fight even when his fellow superheroes are viciously attacked by a dozen guys in Santa costumes: "Odds are it wasn't the real Santa, but how can you ever be sure?" Santa later appears, with a Elf Secret Service team, compulsively hands out gifts such as pencil sets, and tells the Tick to get a grip.
- The Wild Thornberrys:
- An episode that took place in the Himalayas had Eliza searching for the Yeti who supposedly lived there. She eventually discovers that the "Yeti" is actually a doctor who dresses up like a monster to protect the local wildlife. At the end of the episode, a Yeti approaches and helps Eliza fight off some villains; later, Eliza thanks the doctor, but he explains that he wasn't wearing his suit at the time. Eliza ponders what this means, and a loud roar sounds from the mountains...
- Another episode that takes place in Mexico had Eliza running into a friendly old woman who helps her solve her problem of the week. The episode's ending reveals that the woman has been dead for years. Fitting, as the episode was centered on the Day of the Dead.
