He stood up and yelled that he was Jesus Christ and about 10 guys tackled him and tried to cast the demon out and failed so they made him leave the church where he took all his clothes off and walked around naked until the police showed up and brought him to the psych ward.
He said the demon entered into him when he played with a ouija board when he was 8 years old.
Probably because the Lord never told them to do it.
