Adam Cadre (he of Ready, Okay!, Photopia and the MiSTing of The Eye of Argon) has posted the 2008 winners of his Lyttle Lytton Contest, a harder, better, faster, shorter version of the Bulwer-Lytton Fiction Contest.
Adam points out that his examples of sentences that don't belong in the competition may be funnier than the actual winners because they're intentional-intentional comedy, not intentional-unintentional comedy. In a few cases that's true, but most of the examples come across to me as far too precious - the sort of thing you find in humorous genre novels that try to be the next Hitchhiker's Guide (I'm looking at you, Rob Grant), but aren't actually the sort of jokes that make that sort of novel good for me - it's the longer conceptual jokes that make or break that sort of book.
The other thing that stands out is that unintentionally bad writing routinely trumps intentionally bad for the funny. I don't know if it's just that the contest entries tend to be overcrafted, or whether I'm giving credit for the unwittingness of it.
I still suspect the winner cribbed from LaHaye and Jenkins, though.
