For some reason, this scene from Monty Python's, "In Search of the Holy Grail" just cracks me up.

From The Book of Armaments 2:9-21

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 shalt be the number thou shalt
              count, and the number of the counting
              shalt 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 snuf it."

Maynard: Amen.

          All: Amen.

    Arthur: Right! One. . . two. . . five!
