My former boss, who is non-religious Jewish, once claimed that agronomists in Israel were raising Kosher pigs. Since the law forbidding pork said something to the effect of "thou shalt not eat of a beast that trods the ground on cloven hooves and does not chew the cud", these farmers were raising their pigs on little raised platforms so their little piggy feet never touched the ground... This story came from a man that used to complain when he couldn't get matzoh at our workplace cafeteria during Passover...so he could eat it along with his pork and beef hotdog on a standard bun!
