BAPTIST, SOUTHERN: Avoid contact until degree of bible-banging is assessed. Be wary of impertinent questions such as "Do you have horns?" and "Do Jews really make matzah from Christian babies?"
FUNDAMENTALIST, NONDENOMINATIONAL, HILLS VARIETY: Characterized by grubby children with bizarre names such as Hiram and Jochebed. Back away slowly.
FUNDAMENTALIST, NOT OTHERWISE SPECIFIED: Immediately identifiable in August by presence of females in long skirts wearing long sleeves and opaque tights, or other seasonally inappropriate clothing; also note deliberately frumpy sister-wife style clothing and long hair. The male of the species is generally camouflaged as a regular guy. Note: Do not self-identify as Jewish to these people if you have somewhere else to be.
LDS (MORMONS): Identify by presence of many tall, neatly dressed, well-behaved children, or glimpses of sacred undergarments. Children are excellent playmates as long as they do not attempt to proselytize. Mostly harmless.
