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."
So, here's a 2-parter.
Question 1 is easy: Where is this from?
Question 2 is a little harder: What did I find slipped under my door?
I must admit that it left Ral, Rahne, and I a little surprised to hear a rapping for this particular topic...
There is a right answer. Let's see who the best guesser is.
