One Trick Pony is the tell-all biography ghost-written by Diane Nguyen that she finished by the end of Season 1 of BoJack Horseman centering around the show's titular character, BoJack Horseman. BoJack himself isn't a fan of the book, because he is embarrassed that he came off as a terrible person. He has grown more accepting however.

The book won a Golden Globe.


Although Diane was hired as a ghost writer and it's meant to be a memoir for BoJack (the latter even casually mentions to her family in Live Fast, Diane Nguyen that Diane's name won't be on the book), One Trick Pony is constrained to third-person through Diane's perspective rather than BoJack's, and her name is prominently displayed on the cover, making the book a biography.
