Los Angeles, September 21, 2006 – Not only did Steve-O drop his pants and urinate on the red carpet in front of journalists and photographers at Thursday’s premiere of Jackass: Number 2, he had help from costar Ehren McGhehey, who alternately dropped in the path of the stream, and to his knee for a close encounter with Steve’s genitals. But that’s not even the worst of it. Steve-O brought along his father, sister and niece, and peed right in front of them, too. Dad must be so proud!

We didn’t run the photos in all their glory, but you can see the full NSFW frontal here.
