There was a similar rumor floating around in the late 70's.
The story floating around So-Cal was that Jeane Dixon claimed she was short on predictions because the spirits indicated to her that they were; "too busy working on the families of Jehovah's Witnesses".
I don't know how these rumors get started. The Smurf thing as well. I lived in Seattle in the early 80's and there was a story making the rounds about someone going into their kid's room and the child's Smurfs were dancing around on their own. These stories become more detailed and fantastic with each retelling.
Pure, unadulterated BS.
Someone else posted a Smurf story in another thread. I hadn't heard that one before and it was even more bizarre.
