Heh heh ...

It reminds me of the time, at the first computer company I worked for, when we were expecting a visit from some people at DEC (Digital Equipment Corporation), which acronym I thought was pretty universal.

Checking with the young secretary, I asked "Are the people from DEC here yet?", to which she replied "No, but there are some people from Digital waiting in the lobby".

So I have to agree -- one person's ATESK* is another person's puzzled stare.

(*) ATESK = "Acronym that everyone should know"
