Characters Watch The Show???

I've seen this done with other TV shows (I read about two of these with Glee fanfiction) and I was wondering if there were any CM fanfics like these. What I'm talking about is, the characters of the show somehow getting their hands on the episodes and watching them, therefore discovering the future, or going over events of the past.

I have no idea if there are even any fics like this out there, but if you know any, that would be great! :D
