You know how you see these guys coming up to you asking for a donation for some religion? Do what I do, just before they can ask for the donation, stick out your hand and say, in your best salesman's voice, "Can I talk to you about God today?" And then go into a long rant on Gnosticism and the books left out of the bible. Or Buddism, or just any damn thing...politics, the gummint, whatever.
It really turns the tables and gets them all confused and mixed up.
