Sam wrote a list about things he hates about road-tripping with Dean. Sound familiar?

Hey, I need some help. A couple years back (I think) I read about a Supernatural book that was published, but I don't remember the title. It had something to do with Sam writing a list of everything he hated about road-tripping with Dean. Does anyone know ANYTHING about the book? Title, author (aside from Sam), PUBLISHER? Any help at all would be much appreciated.
