First pick a letter. Then pick a fandom and a pairing. (Example: M is for Manpain, JBD/Salty coffee, Reality.) I'll write you a ficlet based it. Movie, tv, crack,
whatever. Go for it.
Possible fandoms: Fallout (all except for 1), LOTR, Luther, Mad Men, Flight of the Conchords, Mass Effect, Doctor Who, and probably some others.
