Scotland leaves the UK, charges England rent on Scapa Flow and similar places. Elizabeth II has apoplexy, Charles III comes to the throne and invades Scotland. Brandishing his burnished blade he yells, "Remember Flodden and Culloden! Up and at 'em, lads!", turns in his saddle, and finds everyone at the pub -- Scots and English, polishing off pints together.

Meanwhile, the Welsh take back the Marches and require everyone to eat leeks at least once a week -- it's called "Leek-a-Week" -- and because of the speech which Henry V of England gave before Agincourt (or at least Shakespeare says he did) tell the House of Lords that because their blood was "gentled" they, too, want to take their rightful seats.

Knowing better, Cornwall, Ulster, Mann, and the rest simply keep their own counsel.
