Who's Dumberer Now?

For years, Austrains and Australians have tried to wearily explain to us 'Merkans about the difference between their countries. They claim it's more than just a syllable: one country has Alps, one has kangaroos. The following exhchange from the classic film Dumb and Dumber perfectly illustrates the point:

LLOYD-Excuse me, can you tell me how to get to the medical school? I'm supposed to be giving a lecture in twenty minutes and my driver's a bit lost.
YOUNG WOMAN-Go straight aheads and makes a left over za bridge.
LLOYD-That's a lovely accent you have. New Jersey?
YOUNG WOMAN-Austria.
LLOYD-Oh! (chuckles, and puts on an Australian accent) Austria!? Well then. G'day, mate. Let's put another shrimp on the barbie!
YOUNG WOMAN-Let's not.

It turns out they have been lying all along.

Just when you thought you had it straight. Sigh.
