Stephen

 Stephen (played by Ian Hecox) is a mentally challenged little boy who usually mistakes the burglar (who comes in every holiday) for the Easter Bunny or Santa.

The Character
Stephen was adopted by his parents. His mother adores him, however, the father often treats Stephen with contempt. He got lost in the Grand Canyon and subsequently, his parents had to search for him. His dad regretted doing so because he wished he did not live with Stephen because he always gets his property stolen by the Burglar.

Stephen is depicted as childish, dim witted and cheerful. He still believes in Santa, despite his father trying to tell him that Santa isn't real.
