Oh, Canada
The best version of this one I’ve seen
Three Canadian guys — a Newfie, a Quebecer and an Albertan — 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 Newfie says, “I’m 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, the oceans were teeming with fish.
The Quebecer was amazed, so he said, “I want a wall around Quebec, so that no one can get through and pollute our perfect culture.”
Again, with a blink of the genie’s eye, there was a huge wall around Quebec.
The Albertan asks, “I’m 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 Albertan says, “Fill it up with water.”
