I remember one doing the rounds where a couple bought a second hand bed to find it was demonized and would buck around the room when they were on it. An elder took it off their hands and pretty soon he was subject to demon attacks and led the whole congregation away from the 'truth.
Another was the one where some JWs went to a door where people were on the oujia board and the Jws asked it a question... the demon replied that it didnot have time to talk as they were too busy breaking up JW families.
