A reversal of the paradigm
, which my grandmother used to recite to me. No, really she did:
"What is the rhyme for porringer?
What is the rhyme for porringer?"
"The King he had a daughter fair,
And gave the Prince of Orange her."
This is presumably a historical reference to the marriage of William and Mary in the seventeenth century, which led to the Glorious Revolution, the Battle of the Boyne and all that stuff. I strongly suspect that Granny Herring, whose didactic instincts were honed by many years as the village schoolmistress, got it from one of the collections by Peter and Iona Opie.
