Anyhow, I for one do not welcome our new Canadian overlords, and I would like to offer my comrades in the no-doubt-soon-to-blossom Hoosier resistance a handy field guide to identifying our invaders:
1) The first major difference between the Canadian and you and I is that the Canadian has two stomachs and a gizzard. If you suspect someone of Canadianness, you should get your pocket knife out and attempt to ascertain how many stomachs they have. Your basic Canadian, afraid of discovery, will flinch back from the knife at their tummy. A patriotic American wouldn't be a'skeered to let you count their innards, since they have nothing to hide.
2) If there is still some doubt, ask the suspected invader "What shape is bacon?" If they reply "Round, eh?" then you've got yourself a Canadian.
We'll cover what to do when you've uncovered the invader in our next briefing. Until then, Viva La Resistance!
