Can't You Read the Sign?

Go To
Sign, sign, everywhere a sign
Blockin' out the scenery, breakin' my mind
Do this, don't do that
Can't you read the sign?
Five Man Electrical Band, "Signs"

A humorous trope in which a posted sign or spoken warning against an action is so precise that you just know that the characters will do exactly that, or just have.

Not to be mistaken for Schmuck Bait, where the sign is the source of temptation. Instead, this trope forbids something that the characters were going to do anyway, or didn't realize was forbidden; often they take no notice of the sign.

Compare Not Cheating Unless You Get Caught and Rules of the Road. Overlaps with I Warned You if the person pointing out the sign is the one who posted it in the first place. For the sub-trope related to barring animals from places of interest see No Animals Allowed.

  • The ubiquitous, not-once-respected "No Smoking" signs from Cowboy Bebop. One of them is even written in German.
  • Haruhi Suzumiya never met a sign she didn't promptly ignore, such as the NO DIVING sign during the pool scene in the anime adaptation of "Endless Eight", while Kyon has never missed a sign that he didn't suffer for. At least, not yet. R.I.P., Kyon's Bike.
  • In Inuyasha, during the fox demon exams, Shippo dangles a rope with a sign attached in front of Inuyasha that reads "Do Not Pull". Inuyasha pulls it, and Shippo pulls out a sign that reads "Idiots Will Pull" complete with fireworks. Needless to say, Inuyasha is very pissed and uses the Wind Scar on Shippo. Needless to say, Rumiko Takahashi loves this gag, and it appears several more times in her works.
  • A favorite gag in Ranma ˝:
    • In one instance, there is a sign saying "Do Not Break Wall". Ryōga breaks it.
    • Early in the anime, Ryōga falls down a hill next to a sign reading "Warning: Landslide area".
    • In the manga, Ryōga, thinking of Akane, hugs a pole that has the notice "Do Not Hug Pole." Because he's so strong, he breaks the pole. And right above the former sign there is another, off-panel in the previous panel, which reads "Do Not Break Pole".
    • An exhausted Ryōga is so desperate he asks a horse for directions. Naturally, there's a nearby sign that reads, "Do not talk to horse".

    • One of the more humorous examples has a one-shot character waiting for Kodachi at a garden while doing a Noblewoman's Laugh. Naturally, there is a sign right outside that says "Please do not laugh loudly inside the garden".
    • Ryū Kumon, while training with his Razor Wind technique, cut into pieces a Bhudda statue bearing the sign "Please don't cut the Bhudda statue into pieces." Later, the statue had been pieced together (with adhesive tape) and sports a new sign: "Please don't cut the Bhudda statue into pieces again." Naturally, Ryū does so while fighting Ranma (and the statue's head is crying).
  • A running gag in the early episodes of Steins;Gate is Okabe using his cellphone while sitting in front of a "No Cellphones" sign. Made all the funnier in that he's only pretending to use his phone, but is always chewed out for it nonetheless.
  • At one point in Yotsuba&!, Yotsuba leans over the arm of an escalator... and hits her head on a sign warning not to do just that.

  • Ron White once talked about having to drive his wife to the bank while having his two dogs in the car with him, who both needed to pee. However, the only grass around was a small lawn in front of the bank with a sign posted saying "No Dogs", and he had no choice but to let his dogs use it.
    Bank Manager: [storming out of the bank angrily] The sign says "No Dogs"!
    Ron: ...The sign's wrong. The sign should say "Two Dogs"!

    Comic Books 
  • In one Archie Comics episode, "A Symbol Problem", Veronica goes to Norway. But everywhere she turns (and whatever she does), she always meets up with a guard who points to a sign which prohibits something she has done. Fed up with everything, she finally decides to show everyone what the place is really like, and changes the sign to say, "Welcome to NO WAY".
  • Played for laughs in a Donald Duck story. He and his nephews go to a foreign country and the nephews climb a wall. On the other side of the wall, a furious man calls their attention to a sign at the top of the wall and asks if they can't read it. As the sign is written in the country's language instead of one they knew, the nephew who answers truthfully says "no". (The wall is so high nobody would be able to read the sign without climbing it first.)
  • The Mask Returns once shows Big Head revealing a bomb (that he himself pulled out from Hammerspace, no less) with the text "Warning: Do not strike with hammer" on it. Guess what he does.
  • A one-panel scene in Scott Pilgrim's Precious Little Life shows him sitting on a couch, right next to a sign that says "Do Not Sit". The Movie reproduced the scene as well (Director Edgar Wright states in the commentary that he thought it was one of Brian Lee O'Malley's best jokes).

    Comic Strips 
  • B.C.:
    • One strip has a character see a sign that says "Do not stand in front of sign". He tries to walk past it, but the other side says "Do not stand behind sign". The last panel shows him standing on top of the sign, a helpless expression on his face.
    • The same character, standing and staring at a sign, implicitly for quite a while. When someone comes along, he asks them, "Hey, what does 'loitering' mean?"
    • Other signs have included "DO NOT EAT THIS SIGN" (Grog ate the pole and spat out the sign) and "DO NOT STAND ON THIS SIGN" (cue rebellious caveman standing on it, despite gravity being 90 degrees from the position he was in).
  • In Bloom County, signs reading "No toad sexing" or other strange restrictions could occasionally be spotted in the background. A visitor to MIT will find the words "No toad sexing" scrawled on the walls in numerous out-of-the-way places. The exact origin of this is disputed.
  • The Far Side did this a few times:
    "Do Not Give the Birds Dutch Rubs"

    "No Projectile Vomiting"
  • Nodwick:
    • Done with a Sword in the Stone.
    • Also:

      Yeagar: I thought it was just a bluff to keep the tourists out.

    Fan Works 
  • In Angry Harry And The Seven, a slowly escalating Running Gag on the Hogwarts Express is Harry Potter placing "Please Knock" signs on the door to whichever carriage compartment he claims, people ignoring the signs, trying to barge in without knocking, getting thwarted by spells, and getting indignant about it instead of learning the manners that Harry Potter is trying to teach.
  • In Chapter 3 of The Great Alicorn Hunt, while panicking over six new alicorns, some dolt activated the klaxon marked "in event of invasion by giant snails", which the situation clearly was not.
  • Guys Being Dudes: Arlo's actions managed to get the Sleepless Bakery to put up a sign reading "No Monologuing". They also have a "No PDAs" sign, which gets used on the main couple.
  • Several instances of these happen in quick succession in Manehattan's Lone Guardian:
    • First, there are several "do not gallop on wet floor" signs in Bronclyn High's pool area. Another sign posted in the same area calls out anypony who thinks that the aforementioned signs are there just for decoration.
    • Second, the same sign posts a warning directed specifically to Gray Ghost that she is not allowed to sleep in the sunshine on the diving board, and that she is not allowed to use "but I didn't see the sign" as an excuse. Of course, she blatantly violates that warning in every respect while waiting for Leviathan to show up for their duel. It is stated that the sign dates back decades to when Gray attended the school as a teenager, implying that she was disregarding the sign even then.
  • Things I Am Not Allowed to Do at the PPC: Rule 339 is a reminder to never ignore signs reading "Spatial Rift: No entry", regardless of where they're posted.

    Films — Animation

There is a sign that says "No Dogs Allowed" at the entrance of the zoo. The Tramp gets around this by inciting a fight between the guard and a visitor, allowing him and Lady to enter the zoo undetected.
  • Luca has a scene where a group of children are shown playing soccer in a plaza where you can clearly see a "No Soccer" sign on a nearby wall.

  • La Cité de la peur:
    • This French movie starts with a very poor slasher film in which a hammer-and-sickle-wielding killer is thrown into a puddle of oil fuel. Next to said puddle is a sign saying "OIL FUEL. DO NOT JUMP IN THERE". When the killer is thrown in the puddle again, the sign now says "OIL FUEL. DO NOT RE-JUMP IN THERE".
    • "Choucroute interdite" ("Sauerkraut forbidden").
  • Clerks: The customers are so stupid, they routinely ask the clerks if they're open. Or how much something is without looking at the 99¢ signs behind them.
  • There is a dramatic, rather than humorous, example in Five Easy Pieces when the coffee-shop waitress points out the "no substitutions" notice on the menu to nihilistic protagonist Robert Dupea as he tries to order plain wheat toast. He politely orders around her rule, but she refuses to accommodate him, saying, "See that sign sir?" (It says "We reserve the right to refuse service to anyone.") "Guess you'll all have to leave. I'm not taking any more of your smartness and sarcasm!" Dupea's reply is the one line everyone remembers from the movie.
  • Subject of a gag in Gremlins 2: The New Batch, in which a beaker in a laboratory is labeled "ACID: DO NOT THROW IN FACE". Rather unsurprisingly, a Gremlin chooses to ignore this dictate.
  • In The Hot Chick there's two instances of this. When Jessica (in Clive's body) starts strangling Clive (in Jessica's body) the owner of the strip club comes to point at a neon sign that reads "No strangling the dancers". Later on, when Clive returns to his body and tries to run out of the club (because he still has the stripper outfit), the same owner points to another sign: "Monday night is Gay night".
  • In the James Bond movie For Your Eyes Only, a mook ignores the "Burglar Protected" sticker on the window of Bond's Lotus Esprit Turbo when trying to break into it. Then again he didn't expect the car to explode when he broke said window with his gun.
  • In Joey (1997), Billy panics upon seeing an oddly-specific "No Kangaroos" sign on the train to Sydney, though he manages to keep Joey hidden until they get there.

  • At the start of Mad Max 2: The Road Warrior, Max finds a truck abandoned near a sign indicating the Mundi Mundi Lookout, except the Look and Out are separated by a space. Clearly the driver didn't look out, as Max finds his corpse.
  • In Mary Poppins Returns, a Running Gag is the park keeper pointing out "keep off the grass" signs. He appears in the underwater bath scene, pointing to a sign saying "keep off the sea grass". In the balloon scene when the park is full of people, he looks grumpy while they all walk over his beautiful grass.
  • In the park in which the Burly Brawl in The Matrix Reloaded takes place, there's a sign on the wall that reads "No Brawling". It's visible here.
  • Max Keeble's Big Move played on this a bit: When Megan meets Jenna for the first time, Jenna tells her that the seat she's sitting in actually belongs to her. Megan asks if it has her name on it or something, to which Jenna reveals that the seat does have her name on it.
  • Not Another Teen Movie:
    • A sign on the ventilation duct work states: "Limit Two Horny Teenage Boys". When three try to use it, it breaks.
    • When we first see Areola, she's standing naked in a school hallway next to a sign that says "Dress Code Strictly Enforced".
  • Scary Movie begins with a woman running away from the killer. She reaches a sign which points in two directions, one "Safety", the other "Death". Guess which one she picks.
  • Scott Pilgrim vs. The World: In addition to the "Do Not Sit" joke under Comics, every time we see Scott's sister on the phone, she's doing so under a sign that declares customers who are on their phones will be ignored.
  • In Sgt. Bilko, we get Bilko sitting behind his desk in the motor pool, in front of a huge no smoking sign. "We have rules!" (lights match on sign) "Rules and regulations!" (lights cigar with match, takes puff).
  • Spaceballs:
    • The auto destruct button has a sign warning not to press it unless you really, really mean it. It is ultimately set off semi-accidentally when Dark Helmet gets body-slammed against it.
    • At the start of Lone Star's rescue of Princess Vespa, a group of Spaceballs object to him parking his ship outside the detention block. "Hey! You can't park here!" "Yeah! Can't you guys read? No parking!" The heroes proceed to ignore the demand.
  • In A Stranger Among Us, Fair Cop Emily Eden is seen having a Cigarette of Anxiety right underneath a huge "No Smoking" sign while she waits for word on her injured partner.
  • The Wages of Fear: The characters keep smoking next to a truck full of nitroglycerin, with a sign that says "No flame within 50 feet." Not used for comedy so much as to display the characters disregard for their own safety.
  • Waterworld: The tower bridge of the oil tanker used as lair by the Smokers has a huge "NO SMOKING" sign over it. As their name can hint, they are chain-smoking thugs.
  • The guitar store in Wayne's World has the sign "NO Stairway to Heaven". This sign is based off the real world: so many people would come into music shops and test the guitars by playing "Stairway to Heaven" that clerks would hang those signsnote . In the original theatrical release, Wayne did play Zeppelin's classic, but on home video releases, due to music licensing issues, it's a Suspiciously Similar Song. If anything, that makes it even funnier. "No Stairway! Denied!"
  • A classic example is the scene in The Wizard of Oz when Dorothy and the others arrive at Emerald City. After ringing the bell, the doorman tells them "Can't you read the sign?" He then realizes he had forgotten to put up the sign which reads "Bell out of order. Please knock." It is also evidently the Trope Namer, however, the scene actually goes like this:
    Doorman: Can't you read?
    Scarecrow: Read what?
    Doorman: The notice.
    All four: What notice?
  • Zack Snyder's Justice League. Our introduction to Barry Allen starts with a truck heading towards Central City past a sign that says "Reduce Speed". When the truck causes a road accident, Barry uses his Super Speed to save the life of Innocent Bystander Iris West.

  • In one of John Bellairs's Anthony Monday books, Miss Eells blatantly ignores a "No Trespassing" sign as she and Anthony hop a fence to explore an empty house. The narrator notes that Miss Eells hates such signs anyway, and once stomped on one just to show what she thought of it.
  • Discworld:
    • Soul Music: There's no sign in Blert Wheedon's guitar shop; the "warning" that you shouldn't play "Pathway to Paradise" is when a troll rips your arms off.
    • Used as a weapon in Thief of Time against powerful beings called the Auditors. Since the Auditors follow "laws" and are actually the ones who file the paperwork for them, they obviously must respect what the sign says. When the signs in question are nonsensical, like an arrow pointing left that says "KEEP RIGHT"... And when presented with a sign prohibiting the feeding of the elephant — the Auditors are compelled to seek out an elephant to not feed.
      Ignore this sign. By order.
    • It's also occasionally referenced that an Ankh-Morpork citizen/Wizard, upon encountering a sign not to perform an action, will immediately perform the action just to see what all the fuss is about. Which is why the sign on the stick holding the Portal Window open in The Last Continent says "Do not remove this wood. Not even to see what happens. IMPORTANT."
    • And indeed that if there was a big lever in a hidden cave somewhere with a sign next to it saying "END OF THE WORLD SWITCH. DO NOT TOUCH." the paint wouldn't even have time to dry.
  • Andy Griffiths' Just Series:
    • A hilarious inversion in Just Annoying! Andy takes one of his neighbor's garden gnomes on holiday and sets it up for a photograph (for a postcard) on the diving board at the swimming pool. The lifeguard catches him and tells him that garden gnomes are banned from the pool. When Andy correctly points out that this is not on the sign (which he even checked beforehand), the response is "It shouldn't have to be, it should be obvious".
    • Just Stupid! has a running gag where a park-keeper points out signs ("Keep off the Garden", "No Swimming") shortly after Andy has broken the rule in question, which eventually drives him to try and chase Andy out of the park. Andy's attempts at Loophole Abuse do not help: "I look around to check there's no signs saying 'No Scooping'. No, only one that says 'No Fishing'." Or more brazenly, "As far as I can see there is no sign around here saying 'Do Not Dismantle the "No Fishing" Sign and Turn It Into a Scoop'."
  • In the Kingkiller Chronicle series, taverns near the Arcanum have signs reading "No Sympathy" where "Sympathy" is a form of Functional Magic. Kvothe points out that these signs are likely confusing to persons unfamiliar with magic.
  • Polish book Krzyżacki Poker (in English it would be Teutonic Poker, as in Teutonic Knights Order) utilises this on the cover — we see a character smoking right under the sign "Rauchen Verboten" ("No Smoking" in German).
  • Crops up in the Nomes Trilogy, although in this case the nomes don't understand the signs (or indeed a lot of other parts of our world).
  • "In Ambush" from Stalky & Co. by Rudyard Kipling has Colonel Dabney, who walled his territory with a fence with lots of notice-boards such as "Prosecuted with the utmost rigour of the law. G. M. Dabney, Col., J.P., an' all the rest of it." — and jaws the land and sea out of everyone who fails to keep out.
    Colonel Dabney: You saw my notice-boards? Must have. Don't attempt to deny it. Ye did! Damnable, oh damnable!
  • Thomas the Tank Engine: Several characters face the consequences of ignoring signs.
    • In Down the Mine, Thomas sets out to disobey a sign saying "Danger: Engines must not pass this board". He ends up... down the mine, whose roof is not strong enough to hold the weight of an engine.
    • In Percy takes the Plunge, Percy sees a sign at the quay simply marked "Danger". Thomas tells him that "Danger" means falling down something, telling of how he fell down the mine. When Percy sneaks past it, he finds that the rails slope steeply down to the sea, where he ends up.
    • Bulgy the double-decker bus ends up wedged under a low bridge. Although not referred to in the text, a "low bridge" sign is visible in the original illustration.
  • A Sweet Pickles Book called Xerus Won't Allow It has the title creature (a relative of the squirrel family) posting signs in an attempt to bring order in the town where she lives.
  • Tom Holt's book Who's Afraid of Beowulf? has some Vikings encountering the many signs on the London Underground escalators, and are almost stumped by the one saying "Dogs must be carried". Thankfully, they have a shapeshifter.

    Live-Action TV

    • Also used for ominous foreshadowing — at the end of "The Harvest", Angel appears to be standing next to a sign saying WATCH YOU — appropriate enough for his Mysterious Watcher role. However, when he walks away, we see the sign actually reads WATCH YOUR STEP, foretelling his Face–Heel Turn into Angelus.
    • Similarly, at the end of "After Life" when Buffy confides in Spike, he's standing next to a discarded door with a BEWARE OF DOG sign — a Running Gag with Spike, but this time hinting at the Destructive Romance to follow.
    • And in an episode that addresses the destructive nature of Buffy's Romantic Vampire Boy attraction, there's a road safety poster saying Most Women Aren't Attracted To Dead Guys.
    • In "Faith, Hope, and Trick", shortly after Faith is introduced and doing a tour of the school she stands in front of a poster, Campus Rape Starts Here. It's meant to be a warning on spiking drinks but depending on how you count them Faith would end up a multiple rapist.
  • Community: Jeff takes Beginner Pottery, an "ultimate blow-off class", then sets off Professor Holly's Berserk Button by inadvertently re-enacting the pottery scene in Ghost (1990). Holly growls "One rule I asked you to follow. One. LOOK!" and points to a poster of Patrick Swayze with an "X" over it.
    Holly: I had it made before he died. It's not in bad taste.
  • In an episode of Corner Gas, Lacey tells Karen not to play with her hackey sack in the restaurant.

    • In "Time Heist", all the air vents have the warning "No Entry Under Any Circumstances". Given that Air Vent Escape is a Running Gag in the series, let alone this episode, it's universally ignored.
    • In "The Caretaker", the Doctor complains of the Snooping Little Kid who ignored his Keep Out sign. She points out that it actually reads "GO AWAY HUMANS", which while still pertinent is a bit harder to take seriously.
    • In "The Woman Who Fell to Earth", the Doctor and companions must climb a tall crane to take on the villain of the week. There's a sign on the crane showing a falling man and DANGER OF DEATH — DO NOT CLIMB. It also counts as Foreshadowing, as someone does end up falling.
  • In the first episode of Flight of the Conchords, Sally breaks up with Jermaine in front of a sign that says "No Dumping".

Since he hadn't yet driven out of the building, when the security guards take him to wait for the police, he challenges them to show him the rule that says you can't drive a motorcycle in the casino.

Immediately afterwards another guard is hanging a sign, "No Motorcycle Riding on Casino Floor".
  • In Malcolm in the Middle, when Dewey is first sent to the troubled kids classes, he sits next to a boy with boxing gloves on who asks him if he can scratch his nose.

    Video Games

  • In one town in Dragon Quest IX, there is a small plot of land being used for crops, in the middle of which is a sign saying "do not step on the crops". Naturally, due to its placement and the way you read signs in Dragon Quest games, the only way to read it is to step on the crops.
  • EarthBound (1994):
    • You are warned of in one cave about "Falling Objects". Then the photographer drops from the ceiling to take a picture of you. Granted, he always drops from the ceiling.
    • In a similar light, after visiting the Giant Step, Captain Strong stops you on the way out because of the DO NOT ENTER sign outside the shack (the letters are big enough for the player to read). You have to then go to the Police Office to wrap that issue up and proceed to Twoson. Yes, this is part of the plot.
  • Thanks to the use of tools (As well as a surprisingly wonky but in the player's favour text recognition), the second round of this Family Feud game has some... very bizarre signs given in its "Name a sign everyone seems to ignore".
    • "No Yodeling allowed" (Accepted as "Yield").
    • "No stealing pornography" (Accepted as "Stop").
    • "Pardon the walrus tusks" (Accepted as "Don't walk").

The forbidden items are the items that will work.
  • The Legend of Zelda: In any Zelda game, ignoring odd signs is considered wise.
    • The Legend of Zelda: A Link to the Past:
      • The game has a signpost warning people not to throw objects into an obvious circle of stones sitting nearby. Not only is doing so the only way to get an item required to beat the game, but in this game, signposts themselves can be lifted, making it far too tempting to obtain the item by throwing the signpost.
      • There's another sign that warns you to pay no attention to the man standing next to it. If you go up and talk to the man, he's silent. But if you steal his sign, he gets a bit annoyed and starts following you around...
    • The treasure chest and fishing minigames in The Legend of Zelda: Ocarina of Time are hinted to have banned items; these items can be acquired and used to your advantage.

  • Parodied in Lunar: Silver Star Story Complete. In Meribia, there's a sign on one house that's blocked by a bunch of flowers, making it impossible for anyone in your team to read. After Kyle joins the team, you can bring him to examine the blocked sign. Kyle resolves to find out what the sign says by walking through the flowers and destroying them. So what does the sign say? "Please don't step on the flowers".
  • In MadWorld, you can impale a mook in the head with a sign. Guess what the sign warns you about? There are other signs posted near a ledge warning about the deep water below, almost daring you to throw enemies in.
  • Magical Quest Starring Mickey Mouse (along with its GBA remake, Magical Quest Starring Mickey and Minnie) has a notable inversion of the trope. In the Fire level, the second level to be specific, Mickey (or Minnie, if the player decided to play as her in the GBA remake) arrives at a glass pane containing a fireman's suit that has a sign above it stating that, if there is a fire, someone has to break the glass. As if on cue with his/her entry, a block falls down and smashes the glass and has the fireman's outfit land near Mickey/Minnie, earning him/her the outfit.
  • In Megaman Sprite Game, early on in the game you see a sign that warns you of the legal repercussions of stepping off the path. In order to get close enough to the sign to read it, you need to step off the path. Rather infamously, stepping off the path at any point in the game triggers the Bad Ending. See here.
  • Metal Gear:
  • Mother 3:
  • In Nancy Drew: Ghost Dogs of Moon Lake, there's a post-it note that reads, "Rotten Floorboards! Watch your step" except Nancy has to step right on the rotten boards to get a clear view of the sign.
  • Parodied ruthlessly in The Neverhood. After draining the lake in the second section of the game, it's possible to go down into the empty canyon and see the drain itself. Huge signs are placed all around it: "WARNING! DO NOT JUMP INTO THE DRAIN! YOU WILL DIE!" Klaymen can choose to ignore the signs and leap right in, and sure enough...
  • In the first Oddworld game, inside Rapture Farms, there are various signs of this kind. For instance, near the beginning, "NO TALKING! To fellow employees", referring to the game mechanics of Gamespeak. Indeed, if the player DOES try to talk to one of his fellow employees who is next to a Slig, and the employee responds, the Slig will shoot and kill him. Obviously, Rupture Farms takes their no-talking policy very seriously.
  • Paganitzu: Inscriptions can be found on the wall, giving clues to the game. However, some of them are spoofs of well-known signs, such as "No shirt, no shoes, no service".
  • Pokémon Red and Blue. "Don't touch the poster in the Game Corner. There's no secret switch behind it!"
  • In Portal 2, a sign in 1950s Aperture warns you not to fall down an elevator shaft. Sure enough, the only way to proceed is to portal-fling yourself by falling down the elevator shaft.

      Maximus: It's a tern, and a leaf.
      Nefertiti: Exactly. Turn, and leave!
  • In The Sims 3, one of the towns features a river that happens to pass by the local cemetery, where there is a "No Fishing" sign posted on the river bank. If a highly skilled angler goes to that specific place between the hours of midnight and 4:00 am, s/he can, with the correct bait, catch the elusive Deathfish. Not only does the Deathfish have a high simoleon value if sold, it's one of the two ingredients used by a highly skilled chef to make Ambrosia, which makes its eater grow somewhat younger.
  • In the cutscene that plays when you first enter the beach room of Stay Tooned!, Frank says this to Schmooze, Scoops, Fiddle, Pixel, and Chisel when they relax on the beach, ignoring a nearby sign that says, "PRIVATE BEACH NO TRESPASSING". When the toons refuse to move, Frank beats them up and buries them up to their heads in the sand.
  • The Are You Afraid of the Dark? adventure game The Tale of Orpheo's Curse has a few instances.

      • Do not open EVER! If you try and open it, you will be dragged inside by a bunch of clothes.
    • There's also another door that says you'll be sorry if you open it. You'll get caught by the Neanderthal Man if you do so.
  • In Undertale, the Ruins have signs warning you to stick to the path and not step on the leaves, each of which can only be read by not doing as the sign says.
  • Wild ARMs uses this gag in Berry Cave. You come across a notice that says 'Do not destroy this sign'. Guess what you have to do in order to continue.

    Visual Novels

  • During the "Pirates of the Oceans Unmoving" arc of Sluggy Freelance, a flashback shows the time when Torg bought Bun-Bun from The Little Shop That Wasn't There Yesterday. Finding exactly what he's looking for, for just under what he could afford to pay, he's smart enough to realize where he is, so he then asks the proprietor for a gorgeous, bikini-clad girlfriend for the single dime he had left. The proprietor then silently points to a sign that reads "Attempting to abuse Magical Shop's magicalness will incur a 10 cent penalty".
  • When the cast of Yosh! visits Japan, the lead female is assaulted by flash perverts in a park, using a classic Japanese tag-team trick, where one sneaks up behind a woman and lifts her shirt, while the other is hidden in front with a camera. After she's "dealt" with the two, Yosh comments that there should be signs warning against such assaults. Cue a frame showing several signs hanging and standing all over the park, reading "Warning: Beware of Perverts". In Japanese.

    Western Animation

Ben ignores the warning signs, and Gwen doesn't stop him because she also found it disappointing. It turns out there actually was a good reason for the signs. The giant ball of rubber bands is also a prison for an electrical monster which is unleashed by Ben playing with it.
  • In the MGM Captain and the Kids cartoon "Petunia Natural Park", the Captain contemplates on feeding a sad-looking bear despite a "Don't Feed the Animals Sign". He decides to give him a sandwich, only for bear to turn out to be a cop in disguise who proceeds to beat the Captain with his billy club.
  • Chowder and Mung once hid behind a sign that forbade hiding behind it. Not that the sign would be a good hiding spot regardless of what it read.

    • Similarly, the door to Dexter's room has several signs that say or otherwise mean "No Dee-Dees". They're only there to let the audience know she doesn't read them.
  • The Ed, Edd n Eddy episode "Stop, Look, and Ed" used these as part of the plot. Eddy doesn't want to follow the rules and convinces the other kids to ignore signs as well. Also, Ed goes under some grass instead of on it due to a "Keep off the Grass" sign, and Edd is forced to concede "Well, I suppose technically that's not on the grass...".
  • Family Guy:
    • When Peter and Lois are buying fake documents on the black market in Cuba, they realize they have no money and Peter asks the cashier if they would accept bits of string instead. The cashier replies, "Sorry, store policy" and points to a sign noting... that they don't accept bits of string.
    • In "E. Peterbus Unum," after creating a micronation out of his house and lawn, Peter flaunts his newfound diplomatic immunity by ignoring a "Keep Off the Grass" sign (and singing a blatant parody of "U Can't Touch This").
  • Fillmore!: In "A Forgotten Yesterday", Fillmore is on a jetski in X's lake, and almost crashes into a buoy mounted with a sign that reads "Watch Out For Floating Signs".
  • Futurama:
    • In the episode "The Farnsworth Parabox", Fry and Bender need to move through the Planet Express office undetected. Bender rips the hatch off a superheated steam pipe, above which is a sign that reads, "No Crawling Around". They climb in and, well...
    • In "My Three Suns", while delivering a package to the emperor of Planet Trisol, Fry drinks from a random bottle.

"This got here just in time!"
    • In "Three Hundred Big Boys", Leela goes swimming with a whale with a swimsuit filled with rotten fish as a part of a Zany Scheme. After she dives in, a banner reading, "PLEASE DO NOT FEED THE WHALE" is seen. Leela's suit is eaten. "The suit was ugly! Whale biologist".
  • The Hair Bear Bunch: In "Raffle Ruckus", Hair Bear, having won the zoo in a raffle and now taking on a zookeeper's responsibilities, admonishes some visitors about not reading a "Do Not Feed The Animals" sign after Fumbo the elephant gets his trunk tied up in a fence post reaching for a visitor's peanut.
  • Justice League:
    • In "The Brave and the Bold", while in a lab, Flash tries offering a banana to a gorilla in a cage (unaware that it's Gorilla Grodd, the main villain of the episode), only for the angry scientist to snatch it away and point out the "Don't feed the animals" sign.
    • In "A Better World", Flash ignores a "Please Don't Pick the Flowers" sign and picks one. Poison Ivy calls him out on it.
  • Kim Possible uses this when Ron offers Kim and Monique a pickle in the Club Banana store. Monique points out the sign "No Food, Pickled or Otherwise".
  • Hilariously done in the Looney Tunes short "Cat-Tails for Two". When the cat George is knocked overboard after being fooled by Speedy Gonzales, his friend Benny scolds him by pointing to the sign, saying, "George, can't you read? It says No Fishing!" (It actually says "No Swimming"; Benny clearly can't read.)
  • The Merrie Melodies cartoon "A Day at the Zoo" had an old lady at a zoo trying to sneak some peanuts to a monkey. He throws them back at her and shouts "Hey, sister! Can't you read?!", holding up the "do not feed the animals" sign for emphasis.
  • Mixels: In "Every Knight Has Its Day", there are two signs for this purpose: "Gassy Mud For Mixamals Only" (Found right after Mixadel is thrown into the mud pit by angered Mixamals) and "You Can't Come In Here", when Paladum is not allowed in the zoo by the gatekeeper.
  • My Little Pony: Friendship Is Magic: In "The Lost Treasure of Griffonstone", when Pinkie Pie is about to burst into song, Gilda shows her there is an actual "no singing" sign in Griffonstone (a barred picture of a singing griffon). This puzzles Pinkie to no end, as ponies in Equestria are free to start singing at the drop of a hat wherever they go, and often do so.
  • In the Peanuts special Snoopy, Come Home, Snoopy is continually frustrated by signs that prevent him from going where he wants and doing what he wants, either in general or because he is a dog. Snoopy is actually happy with the last one he sees because it is at the building his previous owner lived and he can use it as an excuse (to break it to her gently) why he cannot to return to her. Snoopy loves both his previous owner and Charlie Brown, but he just isn't particularly thrilled at the thought of living with her other pet, a cat.

  • Rocko's Modern Life: Rocko, looking for a parking space, finds an open one with a "Don't even THINK about parking here" sign next to it. He contemplates for a moment, and a nearby traffic cop immediately issues him a citation.
  • The Simpsons has used this gag several times:
    • In "Homer the Vigilante", Herman shows Homer a "miniature version of the A-bomb" which "the government built in the fifties to drop on beatniks". Homer then goes into a day dream sequence where he rides the bomb a la Dr. Strangelove onto a group of beatniks only for it to cut back to reality where he's actually riding the displayed bomb. Herman then points out the adjacent sign reading "DO NOT RIDE THE BOMB".
    • There's also an instance early on in the episode with Homer's heart attack, when he begins a quiet prayer to God and is shushed immediately by the nurse, who points to a sign reading "NO PRAYING".
    • When Homer is injured in a prison rodeo in "Pokey Mom", he is treated in the prison's medical facility. When Marge remarks that he's being very stoic about the situation, he says he can't complain, then points out a sign saying "No Complaining". The doctor says that the sign's only for the prisoners, so Homer starts letting it all out: "Oh, I hurt so much! And my job is so unfulfilling..."
    • Lisa is trying to ride the bus to see a museum exhibit:
      Lisa: Excuse me, when does the bus get to the museum?

    • Bart is wearing a fancy Batman-style utility belt and the bullies are chasing him. He presses the belt's "Emergency" button, which gives off a siren (telling the bullies his location) and shoots off a flare which parachutes to the ground with the words "Need Help Call Police" on the 'chute. When the bullies run up to him Bart says "Can't you read? Call the police!"

    • And that one time when the two are in a runaway jeep headed toward a cliff (It Makes Sense in Context).

    Real Life 
  • Some shops also have a similar sign to the one in Wayne's World, reading "Customers playing 'Smoke on the Water' may seriously wish to reconsider their motives in buying musical instruments." "Sweet Child of Mine," "Freebird," and "Stairway to Heaven" have also been given this treatment. Working in a music shop must be hell.
  • Sign sometimes seen in science labs: "Caution: Do Not Look into Laser with Remaining Eye".
  • Another favorite "Caution: Only bring cheap watches/credit cards you weren't planning on using anymore near magnet".
  • At least one lab has a sign in the hallway reading: "CAUTION: Active Robot". Do not stand in its way, or else.
  • A collection of bizarre signs, some of which fit the trope, including this "no kissing" sign.
  • Back in the day in St. Louis, there was a wonderful greasy spoon that looked like it was a Hollywood set dresser's idea of a Midwestern diner. It was called "Irv's Home Cooking." When (inevitably) a drunk college kid would ask "Where's Irv?", the stock character waitress would snap her gum, point at the sign out front and say, "Cantcha read the sign? He's home, cooking".
  • And finally, who HASN'T seen a "no standing" sign, only to stand next to it? ("Standing", in the first case, meaning the act of leaving your car running in the parking space). Or, for that matter, a "No Loitering" sign.
  • Four words: "Slow Children at Play". Ambiguous Syntax results because of the lack of a comma between "Slow" and "Children".
  • Thanks to Values Dissonance, this "No Durians" sign falls under this trope just because people might see it and want to try it out to see what's so bad. The main reason behind these signs are that Durians smell indescribably foul. However; you're very unlikely to find the fruit itself outside of South-eastern Asia.
  • Related, but with a different intent are signs that read "No Peanuts" or "No Raw Onions". Given how sensitive peanut allergies can be...not really a laughing matter. The "Raw Onions" case is incredibly specific, too — it's actually on a building at Colorado State University because a professor has a severe onion allergy, just as bad as peanut allergies.
  • "No Turn On Red." The freedom to make a right turn on a red light was introduced in most of the US and Canada as a response to the gas crisis — the idea being that if it's safe to turn, you might as well do it rather than waste gas idling at the light — and it's now a standard part of drivers' education. These signs appear at busy or obstructed intersections and are among the easiest to miss because they tend to be small black-and-white signs. (Plus, shrubberies can block signs off.) It's a fair bet that if you've driven a car in a medium- or large-sized city in North America, you've blown one of these signs without noticing it.
    • Subverted when the "No turn on red" only applies to certain times of the day or certain days. However, the conditions are printed in a smaller size. This ends up with people not turning, but not realize they can turn on red since the condition isn't met.
  • An anecdote about the Battle of Gettysburg: On the first day of the battle, part of the Union army's XI corps had taken up a position in the town's cemetery as a reserve position. During the events of the first day's battle, the rest of the Union troops were driven back into the cemetery by the Confederates. On the second day of the battle, a junior officer to Gen. O.O. Howard (the XI corps commander) jokingly pointed out a sign in the cemetery saying "Shooting and Use of Firearms is Prohibited". The officer asked if they would get in trouble for violating the sign. Shortly after, a cannonball struck the sign and destroyed it. Gen. Howard reportedly quipped, "It appears the ordinance has been rescinded, and the shooting may go on".
  • There was a sign in a mall escalator in the Philippines warning about hitting a sign on the way up the escalator. In other words, it's a sign warning people about hitting their head on it. The real reason it was put up was to get people who aren't paying attention to hit their head on it and duck, rather than to accidentally get them stuck in the wedge where the two escalators meet.
  • One of the last photo sessions The Beatles had was that of the group reclining on a lawn with a "Keep Off the Grass" sign clearly in view.
  • In the early 1980s, a 12-year-old boy visiting Six Flags Over Georgia boarded a car on the rollercoaster The Great American Scream Machine and flagrantly disobeyed a sign and verbal instructions telling riders to keep their arms in the car, holding the bar in front. As a result, the boy's arms were mangled. The boy's parents attempted to sue the park for his medical bills, claiming extra effort should have been used to enforce the rule.
  • One man used a sign that accidentally said something wrong to wriggle out of a parking violation. Specifically, he argued that because the sign actually read "No Stoping" instead of "No Stopping", he was allowed to stop there as he hadn't engaged in any "stoping," that is, mining ore from underground, in the area.
  • Anyone who has ever worked in a customer service job can probably tell you that you could have a huge sign on the front door that says "Closed" with the hours of operation listed below, and someone will still try to pull the door open and bang on it furiously wondering why nobody is letting them in.
  • Gary Oldman recalled during filming of Air Force One, the sound stage had a large sign that said "NO DRINKING, NO SMOKING AND NO EATING ON SET". One day, he saw Harrison Ford standing beneath the sign with a burrito, a cigar and a cup of coffee.
  • Anyone who works in a place with animals as a heavy focus (pet store, zoo, animal shelter, etc.) can tell you that a sign saying "Do Not Tap On Glass" or "Do Not Put Fingers In Cage" is bound to be ignored by children and adults alike, much to the annoyance of employees, the stress of the animals in question, and possibly the pain of the offending fingers. Also, visitors will often ask questions about the animals featured that can be easily answered by reading the signs identifying the animals and listing facts about them.
  • A common sight in Vietnam is walls painted with "Do not dump trash here" or "Do not urinate here", and bags of trash or, um, "water" stains right beneath the lettering.
  • A common complaint is that some door-to-door salesmen (particularly from MLM companies) have ignored “no-soliciting” signs on neighbors’ houses while knocking on doors. Many homeowners, staunchly uninterested in their questionable offers, are generally not happy about engaging with these strangers.
  • The COVID-19 Pandemic had many public buildings and places of business enforce a masking rule with accompanying signage indicating that all people entering must wear a mask upon entry. Many people ignored the signs and went in maskless, which helped spread COVID-19.
  • You can easily buy a sign reading "No Junk Mail" and display it next to, or even on, your letterbox, but you shouldn't expect it to actually reduce the quantity of junk mail you will receive.note
