In the 2 Halls I was in, there were a few. But the most memorable one was an elderly Pioneer who would ask the householder if they wanted to hear about "The Truth". when they quite naturally said ,"NO", he responded with, "If you don't believe in Jesus, Jesus will turn you into a PIG"!
This same guy would determine that if a person didn't answer their bell (which he rang 5 times), they must be not at home. If duty called, he would urinate on their yards, reasoning, he had to go and nobody was home.
I miss him.
