Desert Island Joke 1

Two Irishmen, two Welshmen, two Scotsmen and two Englishmen are washed up on a desert island. One year later the Irishmen are fighting, the Welshmen have set up a male voice choir, the Scotsmen have opened a bank (or did they set up a whisky still) but the two Englishmen have not spoken. They are still waiting to be formally introduced to each other.
