Bad Santa

Bad Santa [2003, directed by Terry Zwigoff, starring Billy Bob Thornton, Tony Cox, Bernie Mac] [imdb]
Jay Kay: True to nature Christmas movie, that does not ignore the harsh everyday during the "time of sharing and jollyness", characters are sick and selfish - just like real life people. Nevertheless it bears the positive Xmas message.
Quote: Willie: Wish in one hand, and shit in the other. See which one fills up first.
