Kicking ass took on a whole new meaning in New York for Briton Mark McGowan. The performance artist is seen crawling across Manhattan in a President Bush mask with an invitation to passers-by to put the boot in.

McGowan said he was "offering the people of America, New York and visitors a kind of therapeutic engagement". "Hopefully people will be able to come and kick me as hard as they like, and gain some comfort in the fact that they can say I kicked George in the ass," he added.

McGowan's self-imposed non-stop ordeal took 72 hours and he covered 36 miles. One of the most controversial performance artists of the UK, McGowan once ate a swan in a protest against the monarchy, the rich and the upper classes..
