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”.
Original poem is The Raven by Edgar Allen Peo (and was feature on a Simpsons episode).
Thanks to a certain someone who pointed this out :).
