Now did the Lord say, "First thou pullest the
Holy Pin. Then thou must count to three. Three shall be the number of
the counting and the number of the counting shall be three. Four shalt
thou not count, neither shalt thou count two, excepting that thou then
proceedeth to three. Five is right out. Once the number three, being
the number of the counting, be reached, then lobbest thou the Holy Hand
Grenade in the direction of thine foe, who, being naughty in my sight,
shall snuff it."
