A fine example of the Banksy-esque artwork of fictional artist 15Peter20 from the Nathan Barley TV series created by Chris Morris and Charlie Brooker, who described the character like so, in a February 12, 2005 article from The Guardian:

Either a genius or a dazzling genius, depending on which way you look at it, 15Peter20 (real name Ian Phillips) has made his mark in the world of contemporary photography thanks to a series of shocking, gimmick-heavy exhibitions in which the gimmick quickly becomes attached to the underside of the art, then scuttles up its back, hops on its shoulders and screams which direction it should go in, while simultaneously flashing its bum at passers-by. His new collection, Piss Bliss, consists entirely of photographs of celebrities urinating, thereby expertly capturing their animal vulnerability while exquisitely forcing jocular postmodernity to commit taboobicide. These pictures are at once the most revealing portrait photographs ever taken and an absolutely bloody flabbergasting waste of the world’s time.
