There are two things.
In the early and mid 80s there were Witnesses saying that the cartoon characters The Smurfs were not acceptable for Witnesses. I had two Smurf cartoon books and my mother made me throw them away.
I also remember a sister telling me, in all seriousness, about a woman who was attacks by Smurf dolls!!!! (Yeah right!) I was told that a Witness sister was in her home singing Kingdom Hymns when she saw these two Smurfs dolls that she had gotten for her daughter come out of her daughter's closet and they began hitting her. They then laughed and went back in the closet. At the time it scared me to death, but now I can't believe how grown people can believe in such stupidity.
The other silly story happened about three years ago when I was living in Mexico for awhile. I was talking to a brother in Spanish when he told me than I shouldn't use a certain word that I was repeating. The word was "ojala" which in Spanish means "I hope so." He proceded to tell me this long story that the Moors, who were Moslims for North Africa, had occupied Spain for nearly 800 years. The Moors spoke Arabic so several Spanish words that are spoken today are Arabic in origin. The Spanish word "ojala" came from the Arabic phrase "Oh Allah." Allah is, of course, what Moslims call God. He told that Allah was a false god so Witnesses should not say the word "ojala." Stupid, Stupid, Stupid!
