Three guys, a Canadian, Osama bin Ladin and Uncle Sam are out walking together one day. They come across a lantern and a Genie pops out of it.

I will give each of you each one wish, thats 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 Genies 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 Afghanistan, so that no infidels, Jews or Americans can come into our precious state.

Again, with a blink of the Genies eye, POOF there was a huge wall around Afghanistan.

Uncle Sam (a former civil engineer) asks, Im very curious. Please tell me more about this wall.

The Genie explains, Well, its about 15,000 feet high, 500 feet thick and completely surrounds the country; nothing can get in or out—virtually impenetrable.

Uncle Sam says, Fill it with water.
