Error 404

It is said, "To err is human,"
That quote from alt.times.lore,
Alas, you have made an error,
So I say, "404."

Double-check your URL,
As we all have heard before.
You ask for an invalid filename,
And I respond, "404."

Perhaps you made a typo--
Your fingers may be sore--
But until you type it right,
You'll only get 404.

Maybe you followed a bad link,
Surfing a foreign shore;
You'll just have to tell that author
About this 404.

I'm just a lowly server
(Who likes to speak in metaphor),
So for a request that I don't know,
I must return 404.

Be glad I'm not an old mainframe
That might just dump its core,
Because then you'd get a ten-meg file
Instead of this 404.

I really would like to help you,
But I don't know what you're looking for,
And since I don't know what you want,
I give you 404.

Remember Poe, insane with longing
For his tragically lost Lenore.
Instead, you quest for files.
Quoth the Raven, "404!"
