Roseanne (1988)

Season 9: Episode 7

Absolutely fabulous glam gals Jennifer Saunders and Joanna Lumley (in character as Edina and Patsy) are among the few down-to-earth participants in Roseanne's outrageous Halloween outing. They're guests at an Upper West Side soiree, where new multimillionaires Roseanne and Jackie have gained entrance into New York society. But for grandmother-to-be Roseanne, a witches' coven soon comes into play "a la Rosemary's Baby” and bizarre happenings begin to involve a very pregnant Darlene.
