I can't believe that I found a fic that messed up this series in the most horrific way possible....

Even though it was horrifying, and it kind of ruined red velvet cupcakes for me forever. Some of the fan-made alternate endings are awesome, though. My favorite one is the one where it turns out the whole thing takes place on the set of a movie directed by a ponified version of Alfred Hitchcock.

This fic is famous enough to have a TV Tropes page, too: http://tvtropes.org/pmwiki/pmwiki.php/Fanfic/Cupcakes

What I find cool about this fic is that Pinkie Pie... doesn't really break character, really. You know, aside from the whole mutilating Rainbow Dash to death thing. She keeps that upbeat, bubbly personality the whole time, treats it like a party, and refers to Rainbow Dash as her friend. And that's what makes it scary. It basically does to Pinkie Pie what The Sacred and the Profane did to Aziraphale.

I hear that in certain civilizations this fanfic is worshipped by bronies as a vengeful pagan deity, and every full moon they sacrifice cupcakes made of ponyflesh to it.

Not the worst I've had the misfortune to 'read' (I skimmed it to dampen the squick), but still pretty damn disturbed.

I wonder whether there's actually any value in sporking it. Some things are so bad they can't be made bearable and/or enjoyable even with the PPC's wacky hijinks.
