I can imagine a Johova witness coming up to a satanists house. He rings the door bell and the satanist opens the door. "Would you care to take a minute to talk about our lord and sav-" He looks in the back of the house and there is a group of satanists about to sacrifice a goat in the middle of the room. Everyone looks at him and the witness makes his fingers into a cross and yells. "REPENT REPENT FOUL DEMONS!!!" Then the satanist shuts the door on him. Another satanist walks up and asks. "What was that about?" "I dunno just some Johova witness" "Okay" *turns around and slits the goats throat* "HAIL SATAN!"
