A Englishman and a Scot are walking along the beach when the Englishman kicks over a lamp and a genie appears. He grants them one wish each. The Englishman says “I wish a hundred foot tall and 100 feet wide wall surrounded England, and no-one can get in or out.” The genie snaps his fingers and says “It is done.” He then turns to the Scot, who says “Fill it with water.”
