The synopses by the various participants are then posted anonymously, for all to read and boggle at. The first two fandoms are already up, and you should go check out the crack: Carnivale and Azumanga Daioh.
While I'm not allowed to say which synopsis I wrote, I am allowed to reveal the fandom, which was Azumanga Daioh. The songvid is brilliant, I highly recommend it, and the summaries are utterly cracktacular, even if I do say so myself. :)
Go. Read. Giggle.
