Funny/clever/creative HTTP error pages

Question

I'm sure many of us have seen or heard of amusing ways to express the standard HTTP errors, like "404 Lost in Cyberspace" instead of "404 File Not Found". What are some of the funniest/cleverest/most creative error pages or error messages you've seen, or can think of? (Somewhat similar to this question on StackOverflow)

I know this isn't a specific question with a single answer but it is relevant to site admins who want to keep their visitors happy (or terrified, if you prefer ;-) I'll certainly be looking for inspiration for my own website's error pages.

Answer 1

I really like the classic manic depressive webserver at, for example: http://pages.cs.wisc.edu/~veeve/404.html

Answer 2

Answer 3

404 Research Lab

Answer 4

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".

Answer 5

A classic satire using the style of an IE 404 page:

These Weapons of Mass Destruction cannot be displayed

The weapons you are looking for are currently unavailable. The country might be experiencing technical difficulties, or you may need to adjust your weapons inspectors mandate.

Answer 6

This isn't exactly a 404 page - ...or maybe it is? Kind of an anticipated 404

Answer 11

Clever: For 401 error pages i really like the idea of a simple form for retrieving lost passwords. I blogged about this recently: Improving HTTP Authentication.

If you ask Google "Find Chuck Norris" and then hit feeling lucky, you get this one: http://www.nochucknorris.com/

Answer 13

This one is my all time favorite, generated from a dead link http://www.jacksonhole.com/tram/index.html

OOOH, FACEPLANT! (404 ERROR)

Sorry, this page does not exist.

Not sure how you got here, but we're glad you came. So let's try to figure this out together.

Surely there has never been a more apt expression of 404.
