An unknown guy stripped off his clothes only with red underpant and did backflips and dances around the outside of nightclub 'Opera' in Los Angeles at night of August 10, 2007. At the same time Paris Hilton and her sister Nicky Hilton left from the club's car park safely and quietly. I don't know if the guy who acted performing arts just wanted to attract people's attention, and thus help the sisters to escape the cameras of paparazzi.
