>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 Genie's eye, 'POOF' there
>was a huge wall around Afghanistan.

>"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."
