Demons! Yep. This spring, the Discovery Channel is going to have a season filled with accounting's of exorcisms from supposed real life events. If the show gets strong ratings, the following year they will actually film Priests as they perform this feats. Personally I don't buy into that stuff, but it would be interesting to watch an episode to see how they sell it. The mind is a powerful tool, especially to those who are easily influenced.
