Watching televangelists perform their supposed miracles makes for an amusing pit stop while channel-surfing. But then the real horror of the situation sets in that so many people believe a palm to the forehead cures disease. Doesnt the name Marjoe Gortner mean anything to them? They obviously havent seen Marjoe, the 1972 documentary about the young evangelist who, at age 17, decided hed had enough of the con games. After bearing witness to the tricks of his former trade, Gortner pulled a Harry Houdini, using his insider knowledge to expose the chicanery of so-called miracle workers. Nothing heals blindness like a dose of truth.
