Hmm, that reminds me of an occasion many years ago during a faaaaaar too long
(and late) programming session. Characters being output from a program weren't
being displayed on a terminal. In a semi-delusional state I started
thinking of the characters as physical objects that had gotten lost moving around
the hardware: "OK, if they didn't get to the terminal screen then where
are they now?.. they must be in there somewhere." In a moment of lucidity I
realised it was time to go home and get some sleep.

(Does the edge of sanity count?)

While the datasheet is amusing (I was reminded of seeing it decades ago by the
dripping water tap for the drain connection on the IC block diagram.), one could
argue that WOM is actually no more ludicrous a term than ROM. After all, a ROM
was written to (once). An application of WOM could be said to be cockpit data
recorders, where writing and overwriting is continually being done, but you only
read it once, and under exceptional circumstances.
