Tap tap tap. "Nevermore." This sounds like a knock-knock joke gone wrong, but it's actually all that happens in Edgar Allan Poe's "The Raven." In the poem, our narrator is getting over a breakup and wants to be left alone. Alas, a talking raven has other plans. We're not entirely sure why or how, but we do know that the narrator goes insane by the end. Is this because of the raven, or was there more to it?
