Answer:
The Nun's Priest's Tale mocks traditional tales of heroic deeds by exaggerating an ordinary event, such as a fox chasing a rooster, into a grand adventure. For example, the rooster Chauntecleer is described as having courage and strength that are equal to a knight's, and he even defeats the fox in combat by outsmarting him with his wit. Additionally, the rooster's battle against the fox is compared to great military conquests, such as the Trojan War, making it seem far more important than it actually is.
