Three men , a Canadian, Osama Bin Ladin and President Bush are out walking 

together one day. They come across a lantern and a Genie pops out of it. "I 

will give each of you one wish, that's 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. "With a blink of the 

Genie's eye, 'POOF' the land in Canada was forever made fertile for farming.

Osama Bin Ladin was amazed, so he said, "I want a wall around Afganistan, 

so that no infidels and Jews can come into our precious state." Again, with

a blink of the Genie's eye, 'POOF' there was a huge wall around Afganistan.

"President Bush, asks, "I'm very curious. Please tell me more about this wall."

The Genie explains, "Well, it's about 15,000 feet high, 500 feet thick
 and completely surrounds the country; nothing can get in or out---virtually impenetrable."

"President Bush " says, Very impressive, "Fill it with water."
