I actually have a variation on the theme. In this case it's a matter of how a computer term that I thought was fairly universally well known can be misconstrued.
This happened about 10 years ago when I was designing Alpha workstations for the now defunct Digital Equipment Corp. Alpha workstations were designed to run Unix, VMS and NT and other than processor and core chipset differences, they pretty much used the same peripheral components as a standard PC of the day.
Anyway, I was having some difficulty bringing up my latest design and over dinner with my wife I realized that the problem I had been having was probably due to CMOS losing power. I mentioned this to my wife, who although is particularly clueless regarding PC's, otherwise has an excellent memory, so I asked her to remind me about the CMOS before I went to work the next day.
So the next day when leaving for work my wife handed me an index card with the following note.
Don't forget the Sea Moss.
It was the funniest thing I've seen in a long time. I have no clue as to what possible connection she thought Sea Moss had to my work but clearly she had no idea of what CMOS is.
Of course nowadays all your boot settings are kept in Flash and there's no need for battery backed CMOS so people under 30 might not even recognize the term but I assume there are a few codgers out there that know what I'm talking about.
