I shall write an epic bad erotic fanfic based on a bad series of books, file off the serial numbers, and make a small fortune selling it as an original piece of erotica.
Now, to work out a series of books to base it on. Erm.
Okay, I can't think of anything bad. At least, not that I've read.
<thinks some more>
Okay, I was going to suggest something really off the wall like Noddy or the Thomas the Tank Engine books, and then I thought, how about Clive Cussler's Dirk Pitt books? I mean, they are bad in some ways (mainly in a "Clive, do you realise that real people never talk like this??!" kind of a way...). Fanfic based on them could be interesting... Also, some of E E Doc Smith's books are kind of quaintly appalling...
