Three guys – a farmer, Osama bin Laden, and an American engineer are together one day. They come across a lantern and a genie pops out of it.
"I will give each of you one wish, which is three wishes total" says the genie.
The farmer says, "I am a farmer, my dad was a farmer, and my son will also farm. I want our land to be forever fertile."
In the blink of the genie’s eye, the farmers land was forever made fertile for farming.
Osama bin Ladin was amazed, so he said, "I want a wall around Afghanistan, Iraq and Iran so that no infidels, Jews or Americans can come into our precious state."
Again! , in the blink of the genie’s eye, there was a huge wall around those countries..
The American engineer asks, "I am very curious. Please tell me more about this wall".
The genie explains, "Well, it’s about 5000 feet high, 500 feet thick and completely surrounds the countries. Nothing can get in or out. It’s virtually impenetrable."
The American engineer says,"Fill it with water." (H/T: Bob M)
