A Dirty Shame on AllMovie

America's leading titan of bad taste, John Waters, returns to X-rated territory (well, actually NC-17-rated territory, but you get the idea) for this wildly over-the-top comedy. Sylvia Stickles (Tracey Ullman) is a wife and mother living in Baltimore who, along with her husband Vaughn (Chris Isaak) and mother Big Ethel (Suzanne Shepherd), operates a local convenience store. One day, Sylvia receives a sharp blow to the head, which leaves her with a concussion. However, the concussion comes with an unexpected side effect -- Sylvia has suddenly become a sex addict, and is soon attended to by the perverse and lascivious sexual evangelist Ray-Ray (Johnny Knoxville). When it becomes evident that Vaughn can't keep up with her sensual appetites, Sylvia throws herself into the strange netherworld of Baltimore's community of erotic overachievers, which includes her daughter Caprice (Selma Blair), who is living a double life as über-buxom exotic entertainer Ursula Udders. A Dirty Shame also features supporting performances from Waters regulars Patricia Hearst, Mink Stole, Mary Vivian Pearce, Channing Wilroy, and Jean Hill.
