What will they do if they find out the duck is made of wood?
Of course the duck is made of wood:...
BEDEVERE: So, why do witches burn?
VILLAGER #3: B--... 'cause they're made of wood?
CROWD: Oh yeah, yeah.
BEDEVERE: So, how do we tell whether she is made of wood?
VILLAGER #1: Build a bridge out of her.
BEDEVERE: Aah, but can you not also make bridges out of stone?
VILLAGER #2: Oh, yeah.
BEDEVERE: Does wood sink in water?
VILLAGER #1: No, no.
VILLAGER #2: It floats! It floats!
VILLAGER #1: Throw her into the pond!
CROWD: The pond!
BEDEVERE: What also floats in water?
VILLAGER #1: Bread!
VILLAGER #2: Apples!
VILLAGER #3: Very small rocks!
VILLAGER #1: Cider!
VILLAGER #2: Uhhh, gravy!
VILLAGER #1: Cherries!
VILLAGER #2: Mud!
VILLAGER #3: Churches -- churches!
VILLAGER #2: Lead -- lead!
ARTHUR: A duck.
BEDEVERE: Exactly! So, logically...
VILLAGER #1: If... she... weighs the same as a duck.. she's made of wood.
I rest my case.
