Stupid cultural humour.

A guy from Alberta and a guy from Ontario are fighting over a lantern that they just ran across when, suddenly, a genie pops out and grants them each a wish.

"Oh, that's easy," says the guy from Alberta, "I want you to build an impenetrable, 100-foot wall around Alberta, so we can protect our conservative, God-fearing culture from all those Eastern Canada Liberal assholes."

"Done," says the genie. "And you?"

The guy from Ontario just smiles and says, "Fill it with water."
