       After some investigation, it turns out these are called
       'harvard sentences' and are designed to be phonetically
       balanced and used in testing of telcom systems.
       Ah that makes complete sense now. - Alas, not 007.
       
       When talking about this on sdf's #gopher channel, 
   DIR  cat from baud.baby
       shared a phone number that gives an endless stream
       of these: (858) 651-5050
       
       Next time you find yourself in need for some 
       phonetically balanced goodness, you can give that one
       a ring!
