MONK: ... and the Lord spake, saying, "First shalt thou take out the Holy Pin,
      then shalt thou count to three, no more, no less.  Three shalt be the
      number thou shalt count, and the number of the counting shalt be three.
      Four shalt thou not count, neither count thou two, excepting that thou
      then proceed to three.  Five is right out.  Once the number three, being
      the third number, be reached, then lobbest thou thy Holy Hand Grenade of
      Antioch towards thou foe, who being naughty in my sight, shall snuff it.
