Stan Marsh and Kyle Broflovski urge Butters to talk to his family, including his grandmother, whom they mention is visiting him this week.
Stan's campaign is "Make Bullying Kill Itself" which features a video with Cartman dressed in drag and Butters himself paraded in front of everyone in the nude.
