The chairperson selects an object/idea/whatever and announces whether it's animal, vegetable, mineral, and/or abstract. The others have to ask questions to figure out what it is. Whomever guesses the object correctly is given the chair for the next round; repeat ad nauseam.
I'd like to offer a hint without giving the game away, but I'm finding that difficult so I shall say for now that the the last three guesses are quite cold.
