TMZ just posted a video that was apparently shot in New York City earlier this year. The video isn't that clear, but it supposedly shows Justin Bieber and his friends leaving a nightclub through the restaurant kitchen. Before leaving, Justin stops for a restroom break ... by peeing into a mop bucket. His friends laugh in the background and argue that this is some kind of honor for the club. Then, randomly, on his way out, JB uses some cleaning product to spray a photo of Bill Clinton and yell "F--k Bill Clinton."
