I kinda think Xanthe's Back From The Well http://www.xanthe.org/SGA/backfromthewell/thewell.htm counts....

Also, inkscribe did a collaboration with drug-addicted Rodney that fits the description (although I never did read it all the way to the end....). Your Reward is Neither Here nor There by inkscribe & pushkin666 at http://inkscribe.livejournal.com/17021.html

(Sorry my lj/html skills are so pitiful!)

This is an awesome list, and a few I've never read before, so thank you!!
