John admits that he has spanked his 12-year-old son, Jack, when he feels his behavior is out of control. He says the boy can be “extremely violent” and that he is possessed by evil forces. He says he’s so concerned about his son’s behavior, he has arranged for him to have an exorcism.

On Wednesday's episode of Dr. Phil, Dr. Phil points out to John that Jack’s behavior is more likely caused by other contributing factors, such as mental illness and environmental factors, like the way John disciplines his son.

Dr. Phil plays a home video of John picking up his son upside down, placing him on a truck and spanking him numerous times, before the boy slips toward the ground.

“What you’re doing right there is absolute, unqualified child abuse,” Dr. Phil tells John. “That is not OK. And let me tell you how I know that’s not demon possession, because if that boy was demon possessed, he would whoop your ass.”
