Odd. In a freaking awesome way.
It's probably as far from Original Flavor as you can get without getting into straight-up smut. But that's oddly what makes it so funny. Each chapter deals with the characters going through the various episodes of Book 1, but through Facebook interactions. It's well written and even acknowledges memes (Anything from Spider-Lin to Call Me Maybe), while still staying pretty much in character, aside from the Obligatory Swearing. I highly recommend this to anyone within the fandom.
