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, 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, Jews or Americans can come into our
precious state." Again, with a blink of the Genie's eye, 'POOF' there
was a huge wall around Afganistan. "Uncle Sam" (A former civil
engineer), 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." "Uncle Sam" says, "Fill it with water."
