Demon Summoning Week begins with Riff finding a tome of ancient evil in his attic, and he and Torg decide to summon a demon. A mispronunciation turns Torg into a monster, but it wears off. Riff uses the Book of E-Ville to summon a demon in the middle of the highway (where he is promptly run over), and then one in the apartment. Before the demon can take over the world, Riff demands "the price": a case of beer and twenty bucks. The demon gives them the beer, but is a quarter short and is unsummoned.
