->'''Bart:''' Hello, Lisa. Certain differences -- rivalries, if you will -- have come up between us. At first, I thought we could talk it over like civilized people. But instead, ''I've just ripped the head off Mr. Honeybunny!''\\
'''Lisa:''' Bart, that was ''your'' cherished childhood toy.\\
''[Stunned pause]''\\
'''Bart:''' AHHH! Mr. Honeybunny!

A bad guy or [[TheBully bully]] breaks someone's stuff, either trying to upset them, get revenge, [[InterrogationByVandalism get information]], or for any other nefarious purpose. There's a {{beat}}, as we [[ReactionShot see the victim's reaction]]. They're usually looking either utterly deadpan, slightly confused, or oddly, a little smug. Then comes the punchline;

''"That's not actually mine."''

For added {{facepalm}} value, the broken thing actually belongs to the guy who broke it. An alternative is for it to belong to someone [[BullyingADragon much scarier]] [[AlwaysABiggerFish than the]] [[LaserGuidedKarma intended victim]]. There's also another variant where the guy is a PyroManiac, a MadBomber, or [[StuffBlowingUp a destructive guru in general]] like the Smash Doctor and it turns out he was about to destroy the stuff anyway. Added insult to injury if the intended victims criticizes their method of destruction and demonstrates a more effective way.

Believing that he's being cuckolded, the construction worker proceeds to pour wet cement all over the car's interior, not realizing that A) the younger man is actually a car salesman closing a deal, and B) he's just ruined the new car his wife bought him as an anniversary gift.
* A similar one exists where a guy sees police officers writing a ticket for an expensive-looking car that's parked in front of a big office building. He goes up and tells the cops he's not paying the ticket and keeps antagonizing them, with the cops finding ever more reasons for giving the car a ticket (tires too smooth, lights not working, etc.). When they leave it turns out the guy was perfectly honest: it wasn't his car, it was his company's CEO's.

* Creator/DouglasAdams once related a story in which he had bought a package of biscuits on a train and was about to eat them when the guy sitting across from him reached over, opened the packet and started eating his biscuits. Incensed at the guy shamelessly stealing from him (but [[StiffUpperLip too British]] to, you know, ''say'' anything about it) he grabbed the biscuits back and defiantly ate a few himself. Not to be outdone, the other man began eating them just as defiantly. After this carried on for a while, the biscuits were gone and the other man stormed off. Adams, more than a little perplexed, looks down to see his own package sitting there untouched and realized that the ones they'd been eating had belonged to the other guy. He wrote this scene into [[Literature/SoLongAndThanksForAllTheFish the fourth book]] of the ''Franchise/TheHitchhikersGuideToTheGalaxy'' series, in which Arthur Dent relates this experience to an amused Fenchurch.

At one point, Frank finds Jackson's folded coat and thinks he sees something moving under it, so he puts a lit pipe under it to smoke out the "animal", setting fire to it, and then further ruining it by soaking it in water. When Jackson sees the damage done to his coat, he empties tea into the bag Frank is carrying... which turns out to be the head of the firm's bag.
** In "Australia House", an argument between Frank and his next-door neighbour, Mr Lewis, results in the two of them demanding the return of borrowed gardening implements, including a hoe Frank borrowed from Mr Lewis. After the argument escalates to the point that Frank accidentally knocks down the fence Mr Lewis put up between their gardens to keep the Spencers' dog from defecating in his garden, Mr Lewis grabs the hoe and saws it in half, not realising it is his own until Frank points it out.
