Other fandoms of mine needing some dick-ness: Sportsnight & West Wing (apparently something about witty Aaron Sorkin dialogue lends itself to dick jokes.)

#1 fandom not needing it? HP - because it would probably be on sale from the Weasley brothers, and disconnected from a body, but still moving around and jizzing on your face when you opened the package.

Also, check your email tonight: I sent you a more personal (but less phallic) note.
