"It's amazing such shaky buildings can stand up well enough for the characters to walk upstairs in the first place."When the floor suddenly gives way underneath someone, usually due to the boards having been weakened by rot or something heavy falling on them. Often leads to the floor below that collapsing, and then the floor below that in a cascade of disintegrating floors. See also Bullethole Door, where a floorboard (or wall) failure is invoked via More Dakka to create a passageway that wasn't there before.

- The first Teenage Mutant Ninja Turtles movie has this occur in the middle of a fight between the Turtles and the Foot clan on the second floor of April's apartment.

Donatello: Uh, guys, I'm not so sure if this is, structurally speaking... such a good time for your buddies to drop in.

- 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. Add the weight of an incautious mine explorer for an instant revelation of just how large the great big hole underneath them is. This is why one should never enter such workings without the knowledge to identify such hazards in a non-destructive manner.
- This happened to Spike Milligan during his wartime service in North Africa. His artillery section moved into a partially destroyed colonial house formerly occupied by an Italian farmer. They discovered an abandoned but playable piano in an upstairs room. Despite shell and bomb damage to the house, Milligan and his mates (the battery's musicians and dance band) used it for an impromptu band practice session. They then bedded down for the night in the safer and dryer downstairs rooms. During the night there was an almighty crash that led them to believe they were under attack. They discovered the upstairs floor supporting the piano had given way and the instrument had fallen through the ceiling, narrowly missing the guy who'd been playing it earlier.
