There is an adult film company out there that does porn videos made as spoofs on classic sitcoms. Other shows they have done are Three's Company and Bewitched.

Christopher Knight was interviewed about this and his reaction is here - http://www.youtube.com/watch?v=QjXi0_A0Hxw

Not the Bradys XXX: Facing financial difficulties at home due to slow business at his architectural firm,
Mike reluctantly tells his wife and kids that the entire household will be on a budget until business picks
back up and the cash crisis ends. The kids get together and help out by taking on odd jobs, holding car
washes and pitching in wherever they can to help save the family house from bank
foreclosure. Wild fun and mayhem ensue especially when Marcia unwittingly
applies for a job as a ‘figure model’ only to find out she’s about to star in a porn movie!
