John Waters' Pink Flamingos

WARNING: This is extremely gross.  A coworker couldn't believe that I hadn't seen or even heard of this film, especially given this dog doo-doo project.  The film is called Pink Flamingos, by John Waters, and the story is that this scene was improvised.  I tried reading the wiki plot summary, but my head started to hurt by the second paragraph.  It sounds interesting, and I might have to see it because there can't be anything worse that happens in the film, can there?  I have a pretty strong stomach, but this scene gave me pause.
