The CBC has run Heritage Moments for as long as I can remember. I'm not sure if they still do them today, but some were classics. These short little bits covered everything from Jews getting the right to vote to the discovery of Insulin to Dr. Naismith introducing basketball to Americans.
Those ads may have been pretty great, but the following one intrigued and traumatized 2 generations of Canadian kids- in fact, anyone who was raised here will remember it.
If you're in a party and want to find out if there's a Canadian in your midst, bellow out "I smell burnt toast". The reaction is almost instinctive, and usually the same. Watch and find out what it is.
