A Canadian and Iraqi and an Israeli

Three guys, a Canadian, an Iraqi and an Israeli are out walking together one day. They come across a lantern and a Genie pops out of it. "I will give you each 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, 'FOOM' the land in Canada was forever made fertile for farming.

The Iraqi was amazed, so he said, "I want a wall around Iraq, so that no infidels, Christians or Jews, can come into our precious state."

Again, with a blink of the Genie's eye, 'POOF' there was a huge wall around Iraq.
Izzy Goldberg, the Israeli asks, "I'm very curious. Please tell me more about this wall."

The Genie explains, "Well, it's about 150 feet high, 50 feet thick and completely surrounds the country; nothing can get in or out."
Izzy says, "Fill it up with water."
