Lancealot: Guaine, Ector, and Bolwes.
Arthur: That's five!
Random knight 1: Three!
Arthur: Three, three... well we can't risk another frontal asualt, that rabbit's dynamite!
Robin: Would it help to confuse it by running away more?
Lancealot: Oh shut up and go and change your armour!
Arthur: Have we got bows? [Random knight shakes his head "no"]
Lancealot: We have the Holy Hand Grenade!
Arthur: Yes of coruse! The Holy Hand Grenade of Antioch! Tis one of the Sacred Relics Brother Manarch carries with him! Brother Manarch! Bring out thy Holy Hand Grenade!
[Chant of "Dieasu Dominae, Toras aes Requiem" As the hand grenade is taken to Arthur]
Arthur: How does... um... How does it work?
Lancelot: I know not my leige.
Arthur: Consult the Book of Armnements!
Manarch: Armnements, Chapter 2, Verses 9 through 21...
Squire: And St. Attala raised the Hand Grenade on high saying "Oh Lord! Blessith now this Holy Hand Grenade so it may blow my eneimies to tiny bits! With thine mercy." And the Lord did Grin. And he feasted upon the lambs, and sloths, and carp, and oragutans, and breakfast cereals, and fruit bats, and...
Manarch: Skip a bit Brother...
Squire: And the Lord spake saying: "First thou shall take out thy holy pin. Then thou shalt count to three -- no more, no less. Three shall be the number of the count, and the number of the counting shall be three. Four thou shal not count, nor thou count out tow excepting when thou shal proceed to three. Five is right out! Once the number three, being the third number be reached, then lobbeth the Holy Hand Grenade of Antioch, towards thine foe, who being not in thine sight shall snuff it!
All: Amen.
Arthur: Right [pulls pin] One, Two, Five!
Random Knight: Three, sir!
Arthur: Three! [throws hand grenade]
