I thought Canadians didn't like being called Canucks. I was at summer camp when some of the kids discovered that, and of course harassed the Canadian campers with the term. The Canadians responded with yankee, which wasn't a problem for those who came from states north of the Mason Dixon line. But it had a highly satisfactory affect on kids from the south.
I know folks from Newfoundland like to be called Newfoundlanders, not Newfs or Newfies. Do the Canadians have any plans to invade Newfoundland?
