Also says a lot about the desperation of some people to have a child.
It stems from times when the inability to have a child was ALWAYS the fault of the female. Men would/could not accept that they could in anyway be unable to impregnate a female. Absolute bollox I agree but then we live in more enlightened times.
But it remains a good tale and many a pint has been bought by the townies when a local has told them that he is only here by the grace of the Giant on the Hill and his mum's "lonely" night "Up there".
The Yanks are the best ~ but then they'd believe anything (as a certain Bill Clinton well knows). I was conceived and born in North Hampshire (bloody miles away ~ closer to your place in fact) but have a strong(ish) west country accent when I want to and even I have managed to con the odd pint or two of Badgers Best when in the local near the hill.
