The essential moral of Hans Christian Andersen’s story ‘The Emperor’s New Clothes’ for people who live in a modern western democracy is that when the laughing stops, the emperor is still the emperor. Indeed, he is more powerful for having allowed himself to be laughed at. As for the small boy who pointed out his nakedness, he can deal with him later. In his new title sequence for The Simpsons, already shown in the US and due to air in Britain on 21 October, the graffiti artist Banksy tracks away from the Simpson family on its suburban Springfield sofa to show a subterranean Asian sweatshop making Simpsons merchandise. A child dips images of Bart into a vat of acid, kittens are pulped to make stuffing for Bart dolls, the tongue of a beheaded dolphin licks envelopes, an enslaved panda hauls a cart, an exhausted, broken unicorn punches holes in DVDs.
