I have never seen any eccentric characters in Penteocst.
Oh, ok so I am lying. Here are a few that come to mind;
1. Lady in a Southern church when I was a teen whose every testimony during testimony service started out with her crying but semi composed. The more she talked the louder she got and the higher pitched her voice got. By the time she was finished I was surprised she was not shattering glass.
2. Older Lady in Southern church who started every testimony by saying "Brother, I too love the Lord".... then would proceed on. I always wondered what she would do if a woman ever led testimony service. This same woman, around the late 1970's, testified that she had read that the police punch your license plate number in a computer and see inside your car to see if you had any of that mary - ja- wanna!!!!! She just knew that 666 was upon us.
3. Man in my wifes church when she was a teen who used the occasion of the electricity going out during altar service to feel something other than the presence of God.
4. This one did not happen to me but I was told this by an elder from up North. He said they had a brain damaged or mentally retarded adult man in their church who everybody knew looked beyond his antics. However a young visiting evangelist had watched the man and decided he was demon possessed and just needed to be delivered. After laying hands on him, pushing and shaking him a lot while speaking in tongues loudly, and firmly casting the demon out of him the man, who had been standing with eyes closed silently through all of this, suddenly opened his eyes looked up at the preacher and grinning said "Didn't work did it?????!!!!!!!"
