Alan Smithee's Frankenstein.

A quiet town is terrorized by a rash of homosexual murders and Detective Rojas is sent to investigate. Meanwhile, Dr Frankenstein is using the corpses from the graveyard to create his super-man. His work is interrupted when Ron Hardon and fat (male) wife Adelaida seek the doctor's expertise in helping them conceive a baby. Dr Frankenstein realizes that Adelaida must have breasts to become a mother, so he operates accordingly. A bit later, Ron catches his wife having oral sex with Frankenstein and becomes angry. But his anger turns quickly to joy, when Adelaida is suddenly pregnant and instantly has a baby. However the baby dies and, when Ron can't afford another medical session, the couple becomes lethargic. Dr Frankenstein decides to use Ron's body for his super-man experiments, killing him and then reviving him.
