Wicca
From dKosopedia
Wicca is the name given to a strain of modern neo-pagan practice associated with witchcraft.
While slightly more credible than Scientology, Wicca was founded by Gerald Gardner in the 1930's or 40's depending on who you ask. Despite Gardner's supposed magical powers he failed to so much as cure his own Asthma. It is also interesting to note that his own wife never converted to Wicca and continued going to the local Anglican Church her entire life.
