(Heh. "Demon City" is what Rincewind calls "Pandemonium" when he is summoned by Eric, and wishes to escape somehow. "I will certainly spread the word around when I get back to, um ... Demon City?"
Obviously, Eric isn't fooled. "You mean, PANDEMONIUM?!?"
I can just imagine the frazzled Rincewind lying there and being harangued, right after escaping the Dungeon Dimensions. Sheesh. Poor wizzard).
