A Reading from the Book of Armaments:

…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 did feast upon the lambs and sloths and carp and anchovies and orangutans and breakfast cereals, and fruit bats and large chu…

“Skip a bit, brother”

… And the LORD spake, saying, “First shalt thou take out the Holy Pin, then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall 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 thy foe, who being naughty in My sight, shall snuff it.”
—  Monty Python and the Holy Grail

Perhaps the Holy Hand Grenade of Antioch wasn’t so far-fetched after all:

A centuries-old hand grenade that may date back to the time of the crusaders is among a host of treasures retrieved from the sea in Israel.

The metal artifacts, some of which are more than 3,500 years old, were found over a period of years by the late Marcel Mazliah, a worker at the Hadera power plant in northern Israel.

Mazliah’s family recently presented the treasures to the Israel Antiquities Authority. Experts, who were surprised by the haul, think that the objects probably fell overboard from a medieval metal merchant’s ship.

The hand grenade was a common weapon in Israel during the Crusader era, which began in the 11^th century and lasted until the 13^th century, according to the Israel Antiquities Authority. Grenades were also used 12^th and 13^th century Ayyubid period and the Mamluk era, which ran from the 13^thto the 16^th century, experts say.
