This has promise...

From The Hollywood Reporter:

Spike.com has ordered shortform series "James Gunn's PG Porn," which brings together primetime TV stars and leading porn actresses for comic -- and platonic -- vignettes. Safran Digital Group produces and distributes in association with Good Boy Prods.

Nathan Fillion ("Desperate Housewives") and Michael Rosenbaum ("Smallville") join adult-film stars including Aria Giovanni, Belladonna and Sasha Grey in spoofs of the adult-film genre, minus the actual sex, of course.
