The Frenchman and The Torontonian

A guy from Quebec and a guy from Toronto are walking down the
beach. They come across a magic lamp, out comes a genie and
says, “I will grant each of you one wish.” So the guy from
Quebec says, “I wish for a wall 500 feet high around Quebec so
nobody can bug us again.”

GRANTED!

The guy from Toronto says, “Fill it with water.”

GRANTED!
