There's a seen in this zombie movie...can't remember what it's called, the guy gets some sort of zombie infection and it makes him have diarrhea real bad. The scene goes on for twenty minutes. You see a shot of his face all scrunched up with him going "urrrrrggghh" and then it cuts to a giant latex ass with shit pouring out...than back to his face and back to the ass. twenty minutes. And then the opening credits start.
