Once more, from the glories of ThinkGeek, you can own your very own plush version of this:

Holy hand grenade of antioch 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.”
