Earl points to a Playboy centerfold on his wall and says that it was Miss October of 1974. The real Miss October 1974 was Ester Cordet, a brown-haired Panamanian, in contrast to the blond Helen Shaver who, in the film, is supposed to be the woman in the photo. The actual centerfold seen in the film is of Miss September of 1970, Debbie Ellison.
