Somewhere is this group was a thread about 'how will Kenny die in the Halloween episode'. I'm NOT going to search through 800+ messages to find that thread again, so I'll start it up again in case anyone has a guess.
Here's mine: Some 'bad' kids will be going around Halloween night, blowing up pumpkins with M-80's. One will mistake Kenny's round, red/orange parka for a pumpkin and stuff one in there - kaBOOM! His head disappears.
Would even be cooler if the rats show up in costume too, maybe with 'cute, little puppy dog' face-masks on (or something).
