Quoth "the Raven"

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 our servers door.
`'Tis some visitor,' I muttered, `tapping at our servers door -
Only this, and nothing more.'

Presently my soul grew stronger; hesitating then no longer,
`Sir,' said I, `or Madam, truly your forgiveness I implore;
But the fact is I was napping, and so gently you came rapping,
And so faintly you came tapping, tapping at our servers door,
That I scarce was sure I heard you' - here I opened wide the door; -
Darkness there, and nothing more.

Then, in answer of your query, through the net so cold and weary,
Came the answer, dark and dreary:
`'Tis not possible!,' we pleaded, `the browser still conceited,
Remaining blank, we kept repeating, darkness there, and nothing more.
Is there—is there balm in Gilead?—tell me—tell me, I implore!”

Quoth the raven, 404.
