Uhmm isn't the computer version Foo bar as in Foo
bar blatz zam zow
 (I'm not sure about the last ones anymore). I once named a 3B2 310
 Foobar and thought nothing of it. Management came to me and requested an
 explaination until they saw the spelling (I was on a support hotline,
 fubar is a fact of life there). 
Were they worried about the language, or the meaning of the acronym?
I once named a Sparcstation "mofo" and it carries that tag to this day.
(128.32.98.214)  Then again this is a university and there is no management.
:)
I've alway wondered if Morrison and Foerster thought about it before they
picked the name of their website (
mofo.com).  I guess it's approprate for
the subject matter.
