It starts with Randy and a large group of guys dressing up like witches and partying together, drinking and smoking crack around a bonfire. It is a tradition for the guys to party like witches each night the week before Halloween. It looks like a ritual.
While everyone is high and drunk AF, one dude uses a "real" spell book to summon a witch that takes control of the dude. The demonic looking possessed guy hops on a broom then flies into town and starts destroying shit and kidnapping children.
The evil witch keeps doing this giving the other "witches" a bad reputation. They eventually confront the witch, who doesn't give a shit how they feel and ignores their pleas to stop. Full of arrogance and hubris, the real witch thought he was a badass and continued doing what he pleased.
Then a former witch flies in on Air Force One. It's President Garrison dressed up like Orange Man...? I'll admit I have not kept up with the last decade or so of South Park and I'm not sure how this came to be lol.
Anyway, he tells the witch to knock it off and the witch gives Garrison/Trump some lip. Garrison/Trump says something like "You wanna see real power...? Take him out." Then a giant military space satelite opens up, fires lasers and disintegrates the witch into a pile of dust.
I don't know. Sure seems familiar...
How do you leave out the part w/ Trump beating up McConnell, Graham and Paul Ryan with a dildo?
