A reading from the Book of Armaments, Chapter 4, Verses 16 to 20:
Then did he raise on high the Holy Hand Grenade of Antioch, saying,
"Bless this, O Lord, that with it thou mayst blow thine enemies to tiny
bits, in thy mercy." And the people did rejoice and did feast upon the
lambs and toads and tree-sloths and fruit-bats and orangutans and
breakfast cereals ... 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."
