- In one episode a chainsaw that Gaston had meddled with goes haywire, cutting a hole in the floor around his desk and dropping it and Gaston into the office below, where the process repeats itself. After going through three floors, it is still going, several characters have gathered on top of Gaston's desk (Lebrac appreciating the Security Cling courtesy of a female coworker), and one asks how many more floors there are.note
- In another, Lebrac drops termites overnight into Gaston's Gaffophone as a desperate measure to get rid of the damn thing. The next morning, everything made of cellulose is collapsing or disintegrating at the lightest touch. Gaston hurriedly runs to the attic... to find his instrument still there (the termites apparently left it alone due to the varnish on it). An incensed Prunelle asks Lebrac to follow him to his office... just as the two of them are going through the floor.
- And yet another example, Gaston is painting the floor of his office while holding an internal monologue about how he won't be falling for the old 'painted into a corner' gag. Unfortunately for him, his home-made paint eats through the floor and completely disintegrates it, leaving him stranded on the tiny corner he left unpainted.
- Zigzagged in Mortadelo y Filemón: The main characters are exploring a crumbling old mansion when the wooden floor suddenly gives way below Filemon. Mortadelo immediately starts to lament his partner, only to find that there is a stone floor just a few centimeters below the wooden one and Filemon is fine. Relieved, Mortadelo jumps onto the stone floor - which promply collapses, sending the two falling into a hole so ridiculously deep it takes all night before they crash into the bottom.
- Happens somewhat frequently to the Blob, given how heavy he is and his status as something of a Butt-Monkey. Since he weighs several tons he has trouble even with reinforced floors.
- During The Dark Phoenix Saga, this happened to Wolverine as a result of a Gravity Master hitting him with his powers. As Wolverine was busy leaping on him at the time, this resulted in Wolverine and his opponent both plunging through the floor, with a suddenly-much-heavier Wolverine on top. The villain was crushed by his own power.

- The Tom Hanks movie The Money Pit has this. In this case, the hole was already there with a large rug thrown over it, and poor Walter gets stuck in it for several hours.
- A justified variant in National Lampoon's Christmas Vacation, when Clark is trapped in the attic. He deliberately steps between the rafters rather than on them, so his weight is supported only by sheetrock, which, unsurprisingly, eventually gives in.
- The climax of The Ninth Gate (1999) where the floorboards in a ruined castle partially collapse, trapping Dean Corso (Johnny Depp). He is forced to watch Boris Balkan (Frank Langella) triumph.

Donatello: Uh, guys, I'm not so sure if this is, structurally speaking... such a good time for your buddies to drop in.
(Foot soldiers drop in through the skylight; seconds later epic floorboard failure occurs)

- Old mine workings. What looks like a solid rock floor may be only a layer of stone debris covering a structure of ancient timbers which have spent the last two hundred years or so gradually rotting away to the point where the only reason they are still up is that they haven't fallen down yet.

This is why one should never enter such workings without the knowledge to identify such hazards in a non-destructive manner.
