I don't think this is exactly what you had in mind, but it's one of my favorite pieces of crack.

This may not have been what I was thinking of, but man it was pure gold! Soooo funny and sweet, I loved it! Thanks a bunch.

Comment-fic in which Dean has a wet dream about pie: Three Point One Four (http://blindfold-spn.livejournal.com/2172.html?thread=2763132#t2763132)

Dean/Cas, which I know you don't prefer, but in this one Dean attempts to seduce Cas with trying various flavors of pie, though neither of them realize that's what's happening, according to Sam. I read this one when I decided to branch out of Wincest a little bit, and it was adorable and made me think Dean/Cas is more thank ok. Plus, Sam POV and Cas' reactions to various pie slices are fun: Sam Is a Genius (http://deancastiel.livejournal.com/2361927.html)

Long Sam/Dean casefic, which is also not really what you wanted (so, at this point, I'm sure you're like, eyeroll, did you read the post?), but it's chock full of descriptions of food, the boys' reacting to food, and the boys talking about food - more than any other SPN fic I've read that wasn't Dean/Cas/Pie: Things We Carry With Us (http://lovesrain44.livejournal.com/42788.html)

Ha. Definitely no eyeroll from me, these are awesome! And honestly, who says no to good casefic? Crazy people, that's who.
