It is one of the great mysteries - what did Mary and Joseph do with the gold those nice old men gave them when they were shacked up in Bethlehem? Imagine they had used some of it to buy the maximum number of Premium Bonds. Alright, I know that's not possible, not least because Premium Bonds were only introduced when Harold Macmillan was Chancellor of the Exchequer in 1956, but this is an illustrative exercise. The point is, after 2,013 years, and on the balance of probabilities, Mary and Joseph would still be waiting for their first £10,000 prize. Sure, they should have bagged a £5,000 prize some time ago - certainly by the time the Black Death was plaguing Europe. As for a £10,000 nugget, that could still be 600 years away. And realistic prospects of anything bigger? Forget it. Now you really are talking miracles.
