That's the insane curator. His real name is Stuart, but I wouldn't call him that if I were you, cause he plays Dungeons and Dragons too much, and he'll probably hit you with his magical long staff or something. Oh, he also herds goats. See that pick-ax? It's filled with heroin. The insane curator also likes to speak Latin. Don't tell him that Latin is a dead language, or he'll cut you with his +5 Holy Avenger. He likes goats and hallucinogenic cheese, too. If you see Stuart, point at him and say: "Power Word Kill!"
