404 Site Not Found

Pretty neat:

Once upon a midnight dreary, while I websurfed, weak and weary,

Over many a strange and spurious website of 'hot chicks galore',
While I clicked my fav'rite bookmark, suddenly there came a warning,
And my heart was filled with mourning, mourning for my dear amour.
"'Tis not possible," I muttered, "give me back my cheap hardcore!" -

Quoth the server, "404"

.That's Edgar Allan Poe's Raven slightly modified, by-the-by. Found here. Thanks Hurky.
