MetaFilter has a long history of doing something on April Fool's Day, and for this year we did something big, but subtle. If you were logged in and visited Ask MetaFilter yesterday, chances are you saw this special page of questions that might have looked familiar. They were all questions posed from the perspective of a character in a fictional book, film, or game. Members were also allowed to offer up answers to the characters.
If you missed the page yesterday, read through them and try and figure them out. If you're stumped and want to see the answer key, there's one on the MetaFilter Wiki. There's also a big MetaTalk discussion that covers lots of the hows, whos, and whys of it.
