Z:gnu-www-ja-google-engineering-talk--d0e117-So I looked for a recursive ac/en

So I looked for a recursive acronym for "Something is not UNIX," but the usual four-letter method was no good, because none of those was a word. And if it doesn't have some other meaning, it's not funny. So I thought, "what else can I do, hmm?" Nothing came to me, so I thought, "I'll make a contraction, then I could get a three-letter recursive acronym." I started substituting all 26 letters: ANU, BNU, CNU, DNU, ENU, FNU, GNU! Well, "gnu" is the funniest word in the English language, so that had to be the choice. If you can call something "GNU," it makes no sense to pick anything else.
