Reese's Pieces are a peanut butter-flavored candy manufactured by The Hershey Company for the North American market. They are circular in shape and covered in candy shells that are colored either yellow, orange, or brown. They can be purchased in plastic packets, cardboard boxes, or cup-shaped travel containers. The candy was introduced in 1978 and launched throughout the United States in 1980. Peter and Brian Griffin lure James Woods to a wooden crate with the candy as bait in "Peter's Got Woods" and "Back to the Woods".
