The Last of the Mullets is a book and film in Grand Theft Auto: San Andreas. It is a parody of the novel The Last of the Mohicans (or perhaps, more specifically, the famous film it was made into), as Mullet and Mohican (another word for mohawk) are both hairstyles associated with rock music.
The book can be seen on the bed of some of the player's safehouses and in the floor of some houses during the burglary mission, while the film is advertised on posters outside movie theaters around the state. Interestingly, the book's cover and the film poster are the same, down to the tagline "Comming Soon to a Cinema Near You".
