A situation where a character doing something minor seemingly causes some major effect, although it's obvious that's actually not the case. If the character is an animal, young, or just plain stupid, they might think that they actually (say) caused a explosion by pointing their finger. Otherwise, they'll simply be shocked and confused. Take, for example:
Alice and Bob are playing around in the woods, Flynning with some sticks. But when their sticks clash, they hear a massive explosion! Did the clashing of two seemingly normal sticks sound off such a massive bang?
Of course it didn't, but the gag is that it seemed like it did. What actually happened was dynamite detonating about half a mile away to open a mine, or a warship firing its guns in the distance, or something similar; they just heard the explosion at the same time their sticks hit.
The name comes from the logical fallacy of Correlation vs. Causation (two things happening in succession or together does not imply that one caused the other). This is where the humor or irony in this trope comes from.
Often Played for Laughs (or at least irony). Framed for Heroism is a specific subtrope. It can, however, be Played for Drama, as it can be used to reveal something ominous (like an invasion or gunfire). If a minor act truly does have a catastrophic effect, that is Unwitting Instigator of Doom.
Compare Retroactive Wish, where it's assumed something happened because a character wished for it, but it's just a coincidence. Compare and contrast False Cause, where the lack of causation isn't immediately obvious.

- Naruto: A trio from the Cloud Village are headed to Konoha. On the way, Karui throws a rock at Omoi, which misses and falls into a valley. Omoi immediately freaks out, imagining the rock somehow causing a massive rock slide which would level Konoha.

(The third member of the team is the Only Sane Man who quickly dispels the notion.)
- In episode 12 of Carnival Phantasm, Emiya Shirou and Tohno Shiki are caught by the lead girls of their Unwanted Harems trying to pull a Two-Timer Date.

- Invoked darkly again in the stampede scene; Simba is practicing his roar (nudged on by Scar), and when he manages a particularly loud one, the wildebeest begin the stampede...which the hyenas had started on a cliff above by attacking them. Scar uses this to his advantage in making Simba think he killed his father.

Mouth assumes the sounds of sirens and gunfire are still coming from the television, and tries Percussive Maintenance to get the noise to stop.
- In Indiana Jones and the Last Crusade, there's a scene where Indy is trying to break into a secret passage in a library, causing loud thumps to echo through the library — coincidentally in time with the librarian stamping a pile of books.

- In the film adaptation of The Stupids, Stanley takes off his shoe and uses the heel to smash a wasp on the hood of his car, just as a bomb inside the vehicle goes off and blows the body of the car to scrap (oddly leaving both the entire front of the car and Stanley completely untouched). Unsurprisingly (considering who Stanley and his family are, see the title of the film) he thinks he did it.
Stanley: That's a well-made shoe!
- Subverted in a Russian Humour story about a warship. A torpedo is fired in the ship's direction, and the captain wants the bosun to prevent crew panic. The bosun comes to the deck and yells: "Let's bet that I can sink our ship with a fart!" and promptly farts. An explosion, fire, everybody jumps into the water. The captain angrily yells: "You're an idiot, bosun, and your jokes are stupid! The torpedo missed!"
- Invoked in another joke. A very old man goes to the doctor for a check-up and proudly mentions that his attractive young wife is pregnant. The doctor tells him a story about a hunter who picks up an umbrella instead of his gun when he goes out one day. A bear attacks the hunter, who raises his umbrella. There's a loud bang and the bear drops dead. "What do you think of that?" asks the doctor. "Impossible!" says the old man. "Someone else must have been doing the shooting." "Exactly," says the doctor.

Will: Come on, man! If I told you to jump off a bridge, would you do it?
- In the episode of Jeeves and Wooster where Bertie goes to stay in Devon, there's a scene where somebody blows a car horn several times to attract his attention, each time just as he's blowing a note in the trombone he's learning to play, with the result that the trombone apparently makes a noise even Bertie can tell trombones shouldn't make.
- In Alice, Charlie gets in one last shot from his crossbow, and then the Hearts Casino explodes. He triumphantly whispers, "Bullseye!" before passing out. Cut to the arrow landing uselessly in the middle of a field.

The time bomb goes off the exact moment Hochstetter fires, making him think he hit the gas tank instead.
- Played for Drama as one of the main Red Herrings in the the Agatha Christie play Spider's Web: teenaged Pippa finds a book about "black magic" and casts a spell to kill her mother's hated boyfriend. When she finds his body, she's convinced she's responsible, but is too hysterical to explain why she thinks that, leading her stepmother to believe she actually killed him.
- In the World of Warcraft expansion Cataclysm, there's a game going on Goblin starting zone, of a sport similar to soccer but played by woodcutting robots of death with a bomb for a ball. In an early beta, the player character takes part in such a game, but kicks the bombball through the goalposts so hard it flies into a nearby volcano, which is destabilized by the explosion. In the released version, the bombball flies in the general direction of the volcano (possibly entering it), but it's actually Deathwing that causes the volcano to erupt.
- Surprisingly Played for Drama in Red vs. Blue Season 11. Almost each of the Reds and Blues individually thinks they're responsible for their ship crashing on Chorus, revealed in snippets throughout most of the season. In actuality, the villains had hit the ship with a powerful tractor beam at the same moment as all of those incidents.
- Shamus Young links the failure of MMORPG game Tabula Rasa and its eccentric creator's space tourism in this Stolen Pixels strip:
The publishers are apparently so enraged at designer Richard Garriott that they've decided to launch his ass into space, which seems excessive to me. But this MMO stuff is apparently a cutthroat business.
- Inverted in 8-Bit Theater, where Fighter wonders why every city they arrive at seems to get destroyed, which Red Mage chalks up to coincidence.
Fighter: Y'know, I assumed this hero of destiny thing would involve a lot less devastation in our wake.
Red Mage: In our defense, those cities might have burned down on their own. That we were there every time it happened is possibly a coincidence.
- The Order of the Stick:
- Invoked when Belkar gets an injunction to prevent Miko from using her "Detect Evil" ability on him, reinforced with a class-action suit alleging that the ability is harmful to the targets:
Miko: This is preposterous! My Detect Evil power is granted by the gods, it is not harmful.
Mr. Jones: Oh really? Are you aware that an alarmingly high percentage of the creatures you have exposed to this radiation are now deceased?
Miko: Yes! Because they were Evil, so I killed them!
Mr. Jones: The plaintiff rests.
- Played straight with a dragon who decided that, since dragons become both larger and Stronger with Age, growing larger should make her stronger, and force-fed herself until she became as wide as she is long.

- In Avatar: The Last Airbender, Momo is playing with some pebbles. He drops one on a rock, but at the exact moment the pebble hits the rock, a nearby Earthbender chucks a rock at a wall, making it seem as if Momo's pebble caused the bang. Made hilarious when it happens twice.
- Bugs Bunny:
- In the cartoon "Oily Hare", a Texas oilman lowers dynamite down Bugs' burrow to blast for oil. Bugs sees the "present" and throws a party. The oilman is then confounded when he detonates the dynamite and hears noisemakers instead of explosions.
- Another cartoon, "Long-Haired Hare", opens with three instances of Bugs playing a musical instrument and interrupting an opera singer, who is practicing in his nearby home. The third instance has Bugs playing a tuba exactly as the singer starts to practice, causing him to clap his hand over his mouth and look briefly shocked.
- In the Count Duckula episode "The Vampire Strikes Back", the title character and his retainers, Igor and Nanny, are at the top of a tower in Castle Duckula, at the bottom of which vampire hunter Dr. Von Goosewing has placed a large quantity of explosives. Nanny finds a case of her homemade sarsaparilla, which Duckula begs her not to open, as "It's lethal!" Just as Nanny uncorks the bottle, Von Goosewing detonates the explosives, and the tower takes off like a rocket. Unaware of the vampire hunter's presence, Duckula assumes the sarsaparilla launched them into orbit, and tries using the bottles of soft drink later in the episode to make a return journey to Earth.
- In Hey Arnold!, "On the Lam": Harold, Sid and Stinky wanted to replicate Mr. Simmons' Soda and Vinegar Experiment. They tied up 7 rockets together and added a whole jug of vinegar and a whole box of Baking Soda (and Tabasco Sauce). The rockets went out of control and landed on the old dilapidated Police Dept. At the same time, Ernie dynamites the old police station, causing the boys to believe they blew up the Police Dept and attempt to escape and become hobos.
- Rugrats: At the end of "Angelica the Magnificent", Tommy points a toy magic wand at a shed that his father Stu was building throughout the episode.

Ponyhead: Harder! HARDER! (forest catches fire) Dang, not that hard.
