Douglas Adams on Australians

I stumbled across a quote from Douglas Adams on Australians which I thought was amusing, and probably very accurate:

As a result of all this hardship, dirt, thirst, and wombats, you would expect Australians to be a dour lot. Instead, they are genial, jolly, cheerful, and always willing to share a kind word with a stranger, unless they are an American. Douglas Adams – English
