Making sport of Americans does seem to be an international pastime.
Sometimes you make it too easy lol!
As the article rightly said Australians and Brits for that matter take a great delight in making fun of themselves, both countries like to put politicians in their place as well as anyone perceived as getting too big for their boots and both countries love the underdog. In America we see that high achievers are taken very seriously and there is little room for the bumbler or eccentric.
What I love is the Australians sense of fairness, the 'fair go', absolutely priceless.
