Three guys, one Irishman, one Englishman, and one 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 in 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 someday be one too. I want all the oceans to be full of fish for all eternity. So, with a wave of the Genie's hand, the oceans were teaming with fish.
The Englishman said, "I want a huge wall around all of England because we're fed up with Jocks and the like coming into our country. This wall will protect us, so that no one will get in for all eternity, it will be England for the English." Again with a wave of the Genie's hand, there was a huge wall around England.
Then it was the Irishman's turn and he asked, "I'm very curious about this wall, Please tell me more about it."
The Genie explains, "Well, it's about 150 feet high, 50 feet thick, protecting England so that nothing can get in or out.
The Irishman says, "In that case, FILL IT UP WITH WATER!"
