Joe, 12, began calling himself "Magneto Man" last year, after his teachers concluded that his presence could crash the school computers. According to Joe's schoolteachers, when other kids used the computer, it would work fine, but when Joe came on it would crash. Now I've heard of the magnetic grandma from UK, who has a similar problem, she has managed to conk off numerous electric kettles, TVs, toasters etc., but Joe's story is quite amusing.
