As I noted yesterday, the "married twins" story is probably too widely disseminated to be finished off entirely. Still, it looks like a smidgeon of doubt is at last beginning to creep in. Writing in today's Guardian, Jon Henley wonders how seriously anyone would have taken the story if they'd heard it down the pub.
Assuming your brain is still functioning like the well-oiled piece of precision engineering it is, your response would, I trust, be: "That's a wind-up if ever I heard one. Think about it for a minute - you mean these two meet by accident, discover not only that they were both adopted but were born on exactly the same day in exactly the same town, and still never pause to wonder whether they might be related? Pull the other one. What did it say on their birth certificates?"
In his piece, Henley references the "excellent Heresy Corner blog". Clearly a man of taste and discrimination. Thanks, Jon.
