" Once upon a midnight dreary, while I pondered weak and weary,
Over many a quaint and curious volume of forgotten lore
While I nodded, nearly napping, suddenly there came a tapping,
As of some one gently rapping rapping at my chamber door.
"'Tis some visitor," I muttered, "tapping at my chamber door
Only this and nothing more. "
