Everyone loves the movies, for a laugh or just to escape normal life for a few minutes. Sometimes a film can do more, pushing the limits of technology or of ideas. And sometimes films just push the limits of good taste. John Waters has done it with films like "Pink Flamingos" and "Polyester." His new project is not a film at all, but a book about his "Role Models." Steve Paulson expected the lesbian stripper Lady Zorro from Waters, but was surprised by the singer Johnny Mathis.
