If she had her way, all we'd show would be Andy bloody Pandy, and she'd stop him climbing into that basket with Looby Lou - let alone Teddy - lest some child be corrupted by the whiff of puppet troilism. And bestiality, I suppose - or would it be bestiality with a teddy bear... rather than a real bear?" - Sir Hugh Carleton Greene, portrayed by Hugh Bonneville in Filth: The Mary Whitehouse Story, on his exasperation at Mary Whitehouse's (Julie Walters) attempts to remove any material deemed mildly offensive from BBC TV.
