 During the night scene right before the attack from the musicians there is a   long take showing what most of the residents of Pig Sty are doing, including   someone crouching on the ground having a "bowel movement". The Hong Kong   version shows a piece of paper with excrement on it implying what he was   doing, while the American version removes the paper and its "contents",   leaving the viewer confused as to why hes simply crouching down with his   pants partially down.
