Joke - World Peace

A Canadian farmer, Osama bin Laden, and an American engineer are 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 total" says the Genie.
 
The Canadian says, "I am a farmer, my dad was a farmer, and my son will also farm. I want the land to be forever fertile in Canada."
 
Pooooof! With a blink of the Genie's eye, the land in Canada was forever made fertile for farming.
 
Osama bin Laden was amazed, so he said, "I want a wall around Afghanistan, Iraq and Iran so that no infidels, Jews or Americans can ever come into our precious Islamic land." Pooooof! Again, with the blink of the Genie's eye, there was a huge wall around those countries.
 
The American engineer asks, "I am very curious. Please tell me more about this wall." The Genie explains, "Well, it's 5,000 feet high, 500 feet thick and completely surrounds these countries........it's virtually impenetrable. Now what is your wish?"  The American engineer smiles and says, "Fill it with water."
 
Pooooof!
 
WORLD PEACE ! !
