This fearless, pudgy gent right here crashed the stage wearing nothing but a pink tutu and “study this” scrawled on this belly, just as photographer Mario Testino was about to announce the winner of the Turner Prize at the Gateshead’s Baltic Centre for Contemporary Art last December. Testino thereby exclaimed, “Wow, art is everywhere,” christening the act. The streaker performance artist Mark Roberts, won’t be the persecuted, the authorities decided: “Although we do not find a criminal offence has been committed, we do not condone your behaviour.” Good. This is the parts where prudes complain a lot.
