You're right -- they obviously change their interviews daily or weekly; here's a Google cache of the interview I meant...
"How do you truly feel about (a) real person slash? (b) real person slash about you? Honestly??"
"a) not sure. Never encountered any, that I know of...
b) I think I probably simply hope (er, and pray) that you're kidding. You are kidding, aren't you?"
It's good to be innocent. I would search for a link, but my brain would melt and leak out through my ears.
There is real person slash out there. Most of them involve NSYNC members. Others include Putin/Bush, Stalin/Roosevelt, and most terrifying of all, God/Satan. Apparently, God likes to be on top.
Disclaimer: I've only heard about it. It's the kind of thing that you talk about, late at night, with the crickets chirping and marshmallows roasting, on the fanfiction topic in forums.
And, someone has written to remind me, this qualifies too, sort of: http://www.neilgaiman.com/journal/2003_01_01_archive.asp#90247304
Sadly, real person slash (Or RPS as it is generally abbreviated) does in fact exist. The basic explanation for it is along the lines of media making celebrities into characters, ultimately every bit as invented and fictional as people who are wholly made up (c.f. the standard Hollywood rumor that there are dozens of gay movie stars, none of whom admit it because it would end their careers). And so the same desire to subvert existing fictions that drives generic old slash becomes a desire to subvert what is seen as the fictional view of celebrities written by Hollywood at large.
And yes, there is RPS about you. The closest I've found in my research (I'm doing my Masters thesis on slash) is this [link removed because. Well, just because, actually. And also because of the thing about brains leaking out of ears, and because I have elderly and respectable aunts who read this journal to see where I am and what I'm doing, and they might get the wrong idea --], but I have no doubt whatsoever that there's more, and that it's probably not as tastefully done, either.
It's interesting to see what's newsworthy these days. I'm happy that this was (as much for the Hugo as for me): http://books.guardian.co.uk/news/articles/0,6109,1034267,00.html
