I read this story about two Christians, a widow and a widower, who ended up having a real life "Yours, mine and Ours" situation with a total of twelve kids and one on the way. About a year after they got married, they all went to the county fair and a couple at a time they visited the Zero Population Growth booth. Imagine the sight of a family of fifteen, one of them in evidence only as a huge bulge in the mother's belly, wlking arounfd the fair with every one of them wearing a ZPG button. :-)
That's great! Makes up for all of the childless, single child, sterile liberals coming through.
