Nonsense. I say that any duck that is called a "ruddy" duck must surely be English. A North American would curse at a duck much differently.

Besides, you Europeans sent Zebra Mussels over here to infest the Great Lakes, and starlings to squawk at us. It is only fair that we inflict grey squirrels, racoons, Canada Geese, and Canadian beavers on you. Just wait until we send over our robins. They must be three times the size of yours.
