And Saint Attila raised the hand grenade up on high, saying,
'O Lord, bless this thy hand grenade that with it thou mayest blow thine
enemies to tiny bits, in thy mercy.' And the Lord did grin, and the people

and breakfast cereals and fruit bats and large chu—

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 shall be
three. Four shalt thou not count, nor either 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 thy foe, who, being naughty in my sight, shall
snuff it.'
