Homer joins a cult and just watch the episode go from there! I thought only Homer could be stupid enough to fall for this, but actually most of Springfield joined the leader's cult. (Maybe theres something in the water in Springfield?)
This is another highlight from my favouite season of the show.
Homer as usual is the most brilliant with lines like "Homer no function beer well without." and after seeing the promotional video for the cult he says "Wait, I'm confused about the movie - so the cops knew that Internal Affairs were setting them up?"
Also the sequence where he kept asking how much the "free" weekend costed.
A brilliant episode!
