Oh come on! I always invite the missionaries into the house. The Jehovah's Witnesses do NOT have a sense of humor, and about all they want to do is see your copy of the Bible.
My favs are the Mormons. I always bring out a bottle of Macallan and plunk it down. I get a carafe of H20 and some ice, and pour myself a stiff one. I always offer the boys a bump, but wouldn't you know, they turn it down.
I listen to the palaver and then I pop the questions. "What about the Mountain Meadows Massacre?" sez I.
After they stumble through that one, I say, "Do you really want to slaughter all Gentiles in the Blood Atonement?"
If they stick it out, I ask, "What are the names of
your wives?"
That most often sends them to the door. Unfortunately, I usually don't get two drinks down before they exit, stage left.
Sic transit gloria mundi!
