Chip Duncan was featured in the Season Twenty-One episode, "Sons A Witches." He participated in a special annual Halloween event with the other men in town. During a spellbook reading, Chip recited a hex that turned him into a witch. He went on to kidnap and torment several children up until he was killed by a laser that President Garrison had fired at him from a satellite in outer space.
Chip has blonde hair and some stubble. After turning into a witch, his appearance changed dramatically. His blonde hair grew long and raggedy, his chin and nose became distorted, and blemishes appeared on his face like that of a typical witch. Under his eyes was a vibrant, green glow, and a permanent smile was plastered across his face that gave him an even more menacing appearance.
He wore a traditional witch attire: a witch's hat, robe, and boots. The robe became tattered during his witch transformation and he carried around an old broom which he used for transportation.
