Three men - a Canadian farmer, Osama bin Laden and an  Aussie are all walking together one day..  They come across a lantern and a Genie pops out of it.  'I will give each of you one wish, which is three wishes in total',    Says the Genie.  The Canadian says, 'I am a farmer and my son will also farm.  I want the land to be forever fertile in Canada '  POOF!  With the blink of the Genie's eye, the land in Canada was forever fertile for farming.  Osama was amazed, so he said, 'I want a wall around Afghanistan , Palestine , Iraq and Iran so that no infidels, Americans or Canadians  Can come into our precious land.'  POOF!  Again, with the blink of the Genie's eye, there was a huge wall around those countries.  The Aussie says, 'I am very curious.  Please tell me more about this wall.'  The Genie explains, 'Well, it's about 5,000 feet high, 5oo feet thick and completely surrounds the countries.  Nothing can get in or out;   it's virtually impenetrable.'  The Aussie sits down on his Harley , cracks a beer, lights a cigarette,  Smiles and says,   'Fill the bloody thing  with water.'
