I don't know, but this suddenly reminded me of something.
Round these parts, we ain't got no Amish, what we got we call Hutterites. Apparently they'll pay young fellers to come around and knock up their daughters, so as to keep their gene pool from degenerating.
And while you're doing your business, the mother sits there and holds the daughter's hand, while the father looks on to make sure there's no funny business.
It's the truth, I tells ya!
