The Can-a-Duh shirt, or simply, the Canada Shirt. Either way, it's a shout out to Canada or just a silly image. It works whether people get it or not. If you are Canadian show your national pride in a fun way. If you are not Canadian, show some love for Canada in a fun way. I mean, who doesn't like Canada? It's like Jamaica with Moose. I am an American but my parents were Canadian, and they tell me I was conceived in Gimli Manitoba, so that's my connection. TMI? Sorry. Just showing some love for the Motherland.
