There was a story of a "pioneer" brother in Canada (I'm in the Florida, USA so this one had to travel really really far) and he cleaned the floors at Toys'R'Us at night. They always locked him in at midnight and did not let him out until the next morning - since it took all night to clean and polish the floors. One night he heard a thump thump sound so he went to an aisle and Ouija boards and stuffed animals were flying around every where. He ran to a phone terrified of this demon visit - but the demons wouldn't let him get to the phone. When they would start to shove him around he would yell Jehovah and they would go away, but he could never get to the phone. He had to wait in the store all night until the Toys'r"Us people let him out.
An apostate kept calling the cops because her radio wouldn't shut off and it was not plugged in or didn't have any batteries. She quickly came back to meetings and the demon left. She is now reinstated. I know this person, by the way. She is a little off.
And I've heard the smurf story too. Ever heard the one about "sprites" talking? (those cool cute toys that had feathers for hair.)
