This one I heard today on the way to an international concert in Oxford, which was organised by the City Council to lift up the mood of its citizens in uncertain times and to show its connections to other parts of the world. The joke concerns the Daylight saving time (DST) this Weekend and goes like that:
When in most countries of Europe and North America the clocks will be adjust forward sixty minutes, in Great Britain the clocks will be adusted backward sixty years.
Good Night friends.
