Two guys, Osama Bin Laden 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 one wish" says the Genie.
Osama Bin Laden said: "I want a wall around Afghanistan, so that no infidels, Jews or Americans can come into our precious state."
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."
Uncle Sam says: "Fill it with water."
