I think he has the same problem I have.  We know that Canada has a Thanksgiving, but at the same time, American schools never teach us about the tradition of another country so I was honestly asking him what Canada does for Thanksgiving.  I wasn't joking in anyway, I wasn't being a dick and saying that everyone from Canada has no teeth, maple syrup for blood, or love hockey.  It was an honest question and the kid flew of f the handle.
On another note, everyone from Alaska lives in igloos.  Now see, that was a joke.
