The Official Fanfiction University of Middle Earth - Camilla Sandman
The fic that spawned mini-Balrogs, Elrond's Naturally Nine, the Morgoth/Sauron feud, Urple, the Witch-Wall - and finally, Gimli got the girl.
One of the best parodies I've read so far. Makes merciless fun of all the fanfic around, complete with bad spelling, Mary Sues and slashing hobbits. So just you know, it's not easy being a ff-author:)
