The 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."

King Arthur: Right. One... two... five.
Galahad: Three, sir.
King Arthur: Three.

Irish Hand Grenade 

A mixed drink typically drunk on St. Patrick's Day, made and drunk like so.
1. Fill a pint glass halfway with a stout such as Guiness.
2. Fill two shot glasses, one with Irish cream such as Baileys and one with Irish whiskey such as Jameson and set them both inside the top of the glass so that they wedge against each other.
3. Pull out the shot of Irish whiskey like you would the pin of a hand grenade and down the shot. The shot of Irish cream will fall in to the stout. Down that next.

"Sure do love these Irish Hand Grenades. Just wish it wasn't so fucking awkward."

2) Worms: MOST POWERFUL WEAPON EVER. Or at least the coolest. A parody of the Monty Python weapon, the holy hand grenade is an awesome weapon which shouldn't be reckoned with.

1)And Saint Attila raised the hand grenade up on high,
