FRENCH KNIGHT:
"You don't frighten us, English pig-dogs! Go and boil your bottoms, sons of a silly person. I blow my nose at you, so-called Arthur King, you and all your silly English ker-nnnnniggitts. *Razz-razz-razz* I don't want to talk to you no more, you empty headed animal food trough wiper! I fart in your general direction! Your mother was a hamster and your father smelt of elderberries!"
And again:
BEDEVERE: "What makes you think she is a witch?"
VILLAGER #3: "Well, she turned me into a newt."
BEDEVERE: "A newt?"
VILLAGER #3: "I got better."
And again:

ARTHUR: "The swallow may fly south with the sun or the house martin or the plover may seek warmer climes in winter, yet these are not strangers to our land?"
SOLDIER #1: "Are you suggesting coconuts migrate?"
ARTHUR: "Not at all. They could be carried."
SOLDIER #1: "What? A swallow carrying a coconut?"
ARTHUR: "It could grip it by the husk!"
SOLDIER #1: "It's not a question of where he grips it! It's a simple question of weight ratios! A five ounce bird could not carry a one pound coconut!"
