Jimmy Dean wrote an autobiography in 2004, called Thirty Years of Sausage, Fifty Years of Ham: Jimmy Dean's Own Story. In the book, Dean talks about Rowlf and his relationship with Jim Henson. He also reiterates the fact that during the show's run, his manager told him that he could get Dean forty percent ownership of Muppets Inc. However, Dean turned it down, saying that he didn't feel he had earned any kind of ownership of Henson's creations.
