I think the point that Professor is trying to make is that, day in and day out, the average American doesn't give a shit about Canada, doesn't really know much about it's politics, etc. Whereas the average Canadian has no choice but to know about American politics, because it is going to impact their lives at some point in the future, guaranteed.
Anyways, nobody makes fun of Canada better than Canadians, and I kind of like the fact that our most famous politician is a crack-smoking, obese f**k.
