YouWho? pointed me towards Litte Yellow Different, where I found a link to the best 404 Error in the world. For those who have been living under a rock for the past decade, are extremely unobservant or maybe just plain stupid, a 404 Error is the "File Not Found" error that you find at the far end of a broken link. You may have seen less humorous versions that bash microsoft, or bash microsoft again, but this one wins the "Best Adult 404" ever for the X-rated animated GIF at the bottom of the page.
This 404 wins the runner up prize because of the wonderful insight we gain into what a web server is feeling.
[EDIT: For a host of 404's (pun intended), check out Area 404
