Y'know in HP, if one of the characters woke up as a llama you'd have to justify it with long and detailed plot points? - Not in popslash *points at second link down*.
...And a Treasure Chest, Too by Kittie, which over the weekend became known as the fish fic - there's humour and trauma and fluff
Walk Like a Camelidae by Lise, also known as the llama fic (this one is hillarious) - fluff and humour and just a smidgeon of angst (and I mean a smidgeon).
and the one I found Rob giggling about is
Things to do in Orlando when you're dead by torch and No pSeud Attached - all I have to say is zombie porn.
P.S. I'm sure there are many long, deep and meaningful fics in popslash, but I'm finding the crack!fic so much fun that I'm really not looking too hard :).
