Happy 404-day! To celebrate this day I collected some great examples of unique and entertaining 404-pages. Which one is your favourite? If you see any others that you think would fit this list you can send them my way and I add them to the list.

Financial Times turned their 404-page into a characterization of some economic policies and how they would describe a missing page.

Adult Swim not only features some great cartoons and animations but also a collection of small stories on their 404-page. The story being shown changes sometimes, so don't be surprised when the story is another when you revisit the page on a different day.

Google is a small surprise, you'd think that they would have a more corporate 404-page but its by far the simplest on this list. At least the title of the tab is a bit unique.

Amazon has by far the cutest 404-page, featuring a new dog at every refresh of one of the employees of the company.

The Norwegian Army definitly didn't miss the mark with their unique 404-page. Or did they? I guess that is up for interperation

The Catholic Diocese of Pittsburgh is very on-brand (can a church be on-brand?) by displaying an image of St. Anthony, the patron saint of lost things.

MIT used to have a cute haiku as an apology on their 404-page but sadly stopped displaying it around 2004. Luckily the WayBackMachine got us covered.

IMDB features a new quote of a movie on every refresh. Which one is your favourite?

New Zealand played into the popular joke of maps not featuring the country due to its size and location by not displaying their own country on their 404-page. Sadly they removed this great joke.

The Australian shows a fake quote of a random Australian politician about the missing page.

Gamespot and Kualo both let the visitor enjoy a little mini-game, first a simple dungeon-crawler and later Space Invaders.
