Witchfinder General vs. Klaus

In "Was it REALLY the WAR of NORTHERN AGGRESSION?!?!?!", out of nowhere the Witchfinder-General appears in Billy Yank's seat to scold Johnny Reb when he argues in-favor of those victimized in the Witch Hunts (mainly by comparing the Confederacy to them), the Witchfinder-General claiming that religious segregation is the correct way to live. This causes Johnny Reb to start channeling more Fascistic comments, turning into Klaus the Nazi as a form of Demonic Possession, leaving to a harrowing exorcism scene. All this goes on while Billy Yank is getting more beer, completely unaware of what is happening in the other room.
