Three people, a Welshman, a Scotsman and an Englishman, are walking along together when they come across a genie.
The genie offers them three wishes.

The Scotsman goes first, saying, โ€œI want a wall across the Scottish/English border to stop the English from coming into my beautiful country!โ€
The genie grants his wish and the Scotsman disappears.

The Englishman goes next, saying, โ€œI want a wall to surround England to keep everyone from invading my proud country!โ€
The genie grants his wish and he, too, disappears.

The Welshman asks the genie to tell him about the wall. The genie replies, โ€œitโ€™s 200 meters tall and surrounds all of England.โ€ The Welshman asks if it blocks off the coast too and the genie nods.
The Welshman then says, โ€œfill it with water.โ€
