I was first amused by this extremely funny exorcism film clip many years ago. When I came to search for it again much later, the only copy I could find was this one, and unfortunately somebody has added laughter. This makes it seem ungenuine. However, the laughter was definitely not there in the original, and I suspect that the film is of a genuine exorcism. If anyone can find the original, without the added laughter, please send us the url.
Several churches take exorcism seriously. Pope Francis has recently re-affirmed the Catholic Church’s commitment to it and, according to some reports, has even performed an exorcism himself (Google “Pope Francis” “Exorcism”).
