Error returned when a server cannot find the requested page.

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".

Sorry, this definition could not be found.

What's up with this new character limit thing, anyway? It pisses me off.

Area code for those inside the Atlanta city limits; Person living "inside the perimeter," as it were, as opposed to 770, the metro area code, for the suburbs... Also a term of pride tossed about casually when representin' the ATL.

Is she 404 or 770?
404, A-Town all da way.
