Once a jolly swagrat camped by the billabong
Under the shade of a coolibah tree
And he sang as he sat and waited while his billy boiled
“The world can never hold enough yogies for me!”
. . . and you know the rest.
Postscript: Until I looked at the logs for this page, I had no idea there really was such a thing as a swagrat. But judging by the kind of pages that come up when I search for the term, fond parodies of Australia’s unofficial national anthem do not enter into it.
