I'll grant you that having Pinocchio wearing a thong was a bit too much (they could have found some other thing for him to lie about, to make his nose lengthen), but I still think that there's a possibility that the Ugly Stepsister was just a really ugly woman. I suppose its not politically correct to make fun of women who are not beautiful by society's standards, and this might have been just such a faux pas, if my interpretation of it was right. I do think they were trying to make fun of Prince Charming by having him appear overly concerned with his appearance, in the manner that we traditionally associate with women. I've seen liberals complain in movie reviews about that!
