Evidence number 1
Guy, a builder, they built a farm, he was in our local village, he found some girl there and had sexings with her. Some time later he returned to his wife and suddenly he understood that his peepee doesn't work. He came to the local witch and she told him "try to inspect the corner of that girl's house where you pissed". He came there and found needles in wood of that corner.
Evidence number 2
My dad was ill, he had hight temperature for a long time. His mother took him to the local witch, she told him to breathe on a frog. That frog made few movements and died. Father got healthy fast.
Evidence number 3
When I worked in oil drilling there was one cool local guy, he always told different interesting stories. One day he told that he is actually a magician. I thought he tries to make up some story again. I told that it is lies and asked him for the proofs. I had problems with my back. Sometimes I could not stand up, sometimes it was pure suffering, so I told him "heal my back and I will believe you". Next day he came and told "now you will never have any problems with your back". And you know... I NEVER EVER HAD ANY PROBLEMS WITH IT, ALMOST 5 YEAR PASSED GOD...
