Attempting to keep myself awake through a totally dead afternoon...
Name any story I've written, and any character in them, canon or OC. I'll tell you three things about that character which I didn't put in the story.
Fic is
HERE and
HERE.
Alternatively:
BITTYFIC!
The rules of bitty fic, if you haven't seen them before, is that you give me a prompt of a character or pairing and a word, event, episode, etc., and I write a fic in 10 words, haiku, or limerick. It's kind of lame, admittedly, but you've got a far better chance of getting an answer than you would if we go for the regular drabble prompts, which tend to result in me going, "Oh, this would make a GREAT 20K word fic..." and never getting done. :) Regarding fandoms - for bitty fics, if I know the names of the characters, I can probably cough something up. So fly free.
