Also:

  "There are three things a man must do
   before his life is done;
   Write two lines in APL,
   And make the buggers run."
   -- Stan Kelly-Bootle, 'The Devil's DP Dictionary'

And:

  "APL is a mistake, carried through to perfection.
   It is the language of the future, for the programming
   techniques of the past: it creates a new generation
   of coding bums."
   -- Edsger Dijkstra
