When I'm approached by fundies doling out religious literature, I simply shake my head and politely say, "No thank you."
However, last summer, while sitting on the front steps of our house, my roommate, my girlfriend and I spotted a car chalk full of well-dressed, neatly kept youths casing our street. "Here come a car load of Jehovah's Witnesses," I muttered under my breath. All six popped out of the little car and approached us.
Their blonde leader spoke, "Hi guys, with the what's been happening in the world, are you worried about things?"
"No. Sorry, we're not interested. Thank you," was my reply. It didn't deter them. Blondie kept rabbiting on. We tried to cut him off, but he won't shut his pie hole. Finally, my roommate, less tolerant than I, barked, "Look, we're not interested, OK? Now get off our property."
They left. Bloody Jehovah's Witnesses.
