The sky is falling: Short Story: The story is listed as Aarne–Thompson–Uther Index type 20C, which includes international examples of folktales that make light of paranoia and mass hysteria.[2] There are several Western versions of the story, of which the best-known concerns a chick which believes that the sky is falling when an acorn falls on its head. The chick decides to tell the king and, on its journey, meets other animals which join it in the quest. After this point, there are many endings. In the most familiar, a fox invites them to its lair and then eats them all.
