Three guys, a Pakistani, a Srilankan and an Indian are out walking together one day. When they come across a lantern and a Genie pops out of it. "I will give you each one wish, that's three wishes total" says the Genie.

The Srilankan 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 Sri Lanka." With a blink of the Genie's eye, 'FOOM' the land in Srilanka was forever made fertile for farming.

The Pakistani was amazed, so he said, "I want a wall around Pakistan, so that no foreigners can come into our precious state." Again, with a blink of the Genie's eye, 'POOF' there was a huge wall around Pakistan.

The Indian 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 the state. Nothing can get in or out."

The Indian says, "Fill it up with water."
