A fatal floor
What can "a fatal floor" possibly mean?
I heard it in a comedy sketch from "A Bit of Fry & Laurie" (the one about grotesquely pretentious critics), and there is a following dialogue there (from 1:56; https://www.youtube.com/watch?v=CHtjl8V483A
- Martin, limp thoughts?
- None whatsoever.
- I thought not. Care to make some up for me?
- Well, this chair is soft, certainly.
- Very soft?
- No, no, it falls short of being very soft. But, of course, if you look underneath we find...
- The floor.
- The floor, precisely.
- Does the floor work for you?
- No, it doesn't work, it doesn't work. The floor doesn't work for me, no, no.
- Is it a fatal floor?
- Well, precisely. You see, the reason the floor doesn't work is 'cause it's all on one level. And, of course, it also falls into the trap of being essentially self-referential.I feel there must be a wordplay here, but I could't find the meaning of "a fatal floor" (according to Google, there is a very (!) strange British information film, but that is all). I thought that maybe it's not a "floor", but I checked the script and the subtitles, and it is. Could somebody help me figure it out, please?
