That I knew about, and it's even fairly well documented; I was
attempting humor about the maybe-somewhat-less-known origins.  (Though
now that I check, those are documented too; see sticky(7) on at least
NetBSD, which also discusses the bit's meaning on SunOS 4, which I
hadn't known until now.)

That one actually isn't a true story; it's just my attempt to break the
question by extrapolating from related traps I know of.  I wouldn't be
surprised if it had happened to someone, though.
