There are three guys walking together, a Newfie, a Quebecer, and a Vancouver guy. They come across a lantern and a genie pops out.

"I will give you each one wish, that's three wishes."

So the Newfie says "I am a fisherman, my dad's a fisherman, and his dad was a fisherman, and my son will be one too. I want all the oceans full of fish"

FOOM the oceans were full.

The Quebecer was amazed, he said "I want a wall around Quebec, so nothing will get in."

POOF there was a wall around Quebec.

The Vancouver guy says "Tell me more about this wall."
The genie says "Well its about 150 feet high, 50 feet thick and nothing can get in or out."
So the Vancouver guy says "Fill it up with water."
