It is a truly memorable fic! I don't have a link but I bet if you google the phrase "dainty prune" you can dig it up.

As for other bad fic... it's been a while since I went looking, but as I recall this gal wrote some of the most endearingly crap fanfic in the entire Transformers fandom. Really nice person. She did (and probably still does) requests, and some people would ask her for THE weirdest shit... you can't help but admire her fortitude in the face of strange fetishes and her own lack of talent. Some unforgettable reads in there.

ETA: Actually looking through her gallery, it looks like she hasn't been around in quite a while. Aw.
