Re: Jehovah's Witness
My house was broken into by Jehovah's Witnesses. It was.. interesting.
I had a friend in high school who lived nextdoor to the local Kingdom Hall. They would come to her home often, and this is how she got them to stop:
They would come and ask if her parents were home, so she responded, "They're busy right now, they're sleeping in pieces in the freezer."
They never returned.
Or.. you could just throw water balls at them. Yeehaw!
