I enjoy hearing variations of this story. The way we heard the rumour here as a kid, was that it was actually Pappa Smurf who got up in the middle of the meeting and walked out, saying "I cant stand this." or something like that. The other part of it I heard was that this one kid had smurf curtains and one night when the parents came to check on him, the smurfs had climbed down the curtains and were doing some sort of evil dance around the child. I cant believe people really believe(d?) in bs like this. I remember my parents talking about it as a joke but not everyone did. As for me, I would watch Gargamel and company every time I layed out of door-to-door. "I'm not feelign well again Mom. I probably wont be better till after Superfriends, I mean later."
In the JW Pantheon, Demons are ancient, supernaturally powerful multidimensional creatures with limited intellect. They can decieve entire world governments, but prefer to hang out in old Led Zepplin alblumbs and 2nd hand clothing. Oh, and they can be dispelled by turning on the lights. Azazel must be stuck in a Teddy Ruxpin somewhere in a city dump, somewhere.
I knew these kids who literally had a really wacked out JW step-mom. One night one of them gets a nightmare. So the mother takes all their stuffed toys (and they didn't have much to begin with) and publically burns it on the front lawn. when her oldest stepson decided to be baptized after some rousing talk at the hall, the woman told the kid (gotta love JW child baptism) that he needed to not talk about it at all while they drove home. She said this was because once a JW youth had announced his dedication to Jehovah at the hall, and a demon had caused the car he was in to wreck, killing him on the way home. This nutcase would openly tell people at the door that Jehovah intervened and stopped the Cuban missle crisis, would discuss ghost sitings and other superstitious BS. She was a pioneer. Actually, she still is, I think. As bad as that is, the sad thing is, people agreed with her.
