Three men, a Canadian, Osama bin Laden, 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, making a total of three wishes," says the Genie.
The Canadian says, "I am a farmer, my dad was a farmer, and my son will also be a farmer. 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 Laden was amazed, so he said, "I want a wall around Afghanistan so that no infidels can come into our precious state." Again with a blink of the Genie's eye -- 'POOF' -- There was a huge wall around Afghanistan.
President Bush says, "I am quite curious. Please tell me more about this great wall."
The Genie explains, "Well, it's about 15,000 feet high, 500 feet thick, and completely surrounds Afghanistan. Nothing can get in or out. It's virtually impenetrable."
President Bush says, "Very impressive. Fill it with water!"
