A bad guy or bully breaks someone's stuff, either trying to upset them, get revenge, get information, or for any other nefarious purpose. There's a beat, as we 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 much scarier than the intended victim. There's also another variant where the guy is a Pyro Maniac, a Mad Bomber, or a destructive guru in general 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.
