Canadians think it’s funny because of that; Americans because of W-era anti-French sentiment combined with antielitism and a historical association of French products with luxury; Germans and English people (at least, very possibly more of Europe) think it’s funny because of their countries’ constant historical antagonism; and people in former colonies think it’s funny because fuck the fr*nch.

Obviously not all of them, but I think it just hits for a lot of people.
