"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
