A cult of which the main premise is the art of thieving. The second art is just being a bunch of absolute wankers. They steal dogs for food, they shoot children in the legs and they let their dogs shit on your lawn.
Gypsy: I need money.
Man: Fuck off.
Man: I had to earn it so why the fuck should you have any of it.
Gypsy: Fair Enough.
20 minutes later the Gypsy arrives with a gang of stolen dogs all of which shit promptly onto your lawn.
Man (from upstairs window): Oh for fucks sake.
Wife: What a bunch of absolute Wankers.
Man goes and gets all of the dog shit into a large disposable bag. Loads his shotgun and finds the gypsy encampment.
