An Englishman, an Irishman, and a Scotsman, are out walking along the beach together one day. 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 Scotsman says, "I am a fisherman, my Dad's a fisherman, his Dad was a fisherman and my son will be one too. I want all the oceans full of fish for all eternity."
With a blink of the Genie's eye, 'FOOM' the oceans were teaming with fish.
The Irishman was amazed, so he said, "I want a wall around Ireland, so that nothing will get in for all eternity." Again, with a blink of the Genie's eye, 'POOF' there was a huge wall around Ireland.
The Englihman 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 nothing can get in or out." The Englishman says, "Fill it up with water."
