The problem with Cindy Sheehan is that she is much worse than Paris Hilton, so they would have to find a way to dispatch with her that is better than how they got rid of Paris Hilton.
Then again, maybe they should make her be Towelie's girlfriend since they both "have no idea what's goin' on."
That would actually be hilarious. If it were not a key part of the episode but Towelie is present and they have to stop by Camp Casey to get weed from his dealer. Wow.
