Scrubs: My Janitor, a JD/Janitor slash story I found on fanfic.net. The first chapter is a tad rough, but the story is hilarious overall. You know those whacked-out thoughts JD always has, the kind of thing that would make him a challenge for me to write? This author pegs them quite well. ;)
Lawrence After Arabia: Moth To The Flame, Lawrence/Feisal slash erotica. This is not the movie with Peter O'Toole-- this is the BBC production with Ralph Fiennes and Alexander Siddig, and the chemistry between them comes off as a kind of longing that really lends itself to this story. This is one of the first stories I read that was truly "erotica" and not simply porn, and the execution is gorgeous. In addition, the research into the politics and geography of the setting really pay off.
House, M.D.: House And Homeboy, a Foreman story at fanfic.net. I really wish people would take more care with their typos and such, but I'm recc'ing this story anyway because it's fun and Foreman is definitely himself here and House is just as evil as you'd expect.
