genie

Three guys, an Indian, a Pakistani and an Afghan are out walking together one day. These 3 guys come across a lantern. When they rub it, a Genie pops out of it. ""I will give you each one wish, that-s three wishes total,"" says the Genie.
The Afghan says, ""I am a farmer, my dad was a farmer, and my son will also be a farmer. I want the land in Afghanistan to be forever fertile."" With a blink of the Genie-s eye, -POOF- the land in Afghanistan was forever made fertile.
The Indian was amazed, so he said, ""I want a wall around
India, so that no neighbors or infidels can come into our Hindustan."" Again, with a blink of the Genie-s eye, -POOF- there was a huge wall around India.

""Hmmmm"", the Pakistani asks, ""I-m very curious. Please tell me more about this wall."" The Genie explains, ""Well, it-s about 150 feet high, 50 feet thick and completely surrounds India. Nothing can get in or out.""
So the Pakistani says, ""Fill it up with water.""
