In the middle of the episode Shelley throws Stan around again. She throws him across the room and he lands on dry carpet. She walks over to him, and he's in a puddle of water. No explanation is offered as to how the puddle got there, but after some research, there is an explanation after all: There was a segment in there after Shelley walks over to Stan where she lights a match and throws it at him to light him up. Then she douses him with water a few times in regret and a puddle forms underneath him. When Comedy Central got the episode to air they asked Trey and Matt to take this piece out, because there have been real-life cases of children actually trying to set other kids on fire with lit matches. Mike Judge got in trouble over portraying this on Beavis and Butt-head, and CC didn't want that kind of trouble. Apparently, though, other nations DO get the original version, with Shelley setting Stan on fire and all.
