This is a classic piece of Ray Bradbury about a country man who buys a mysterious jar from a carnival and becomes a sensation in his small town as a result.
Night after night, a group of citizens meet at his house to discuss the jar and its contents and to try to discover what it it is. each of the citizens ventures a guess, some very complicated like Grandma's explanation, and some very simple like the young girl who thinks that the contents is "the boogieman". Like most of Alfred Hitchcock's hair raisers, this segment has a surprise ending. In addition, in this particular segment, it has a very gruesome ending at that.
