The Assembly Hall is a public building in South Park that appears in the Season Fourteen episode, "The Tale of Scrotie McBoogerballs".
Background[]
After Butters takes all the credit for writing a book that the boys actually wrote because they told him he did in order to avoid getting in trouble with their parents, they head to the Assembly Hall to discuss getting the book banned. Like many of the people who read the book, the members of the school board believe the book has a deeper meaning than the boys intended, when it was really just meant to be as vulgar and disgusting as possible. When the boys fail to get the book banned, they sit outside the Assembly Hall, with Cartman and Kenny coming up with a plan to kill Sarah Jessica Parker and get back at Butters after Stan and Kyle leave.
