While stitching up the hand of a 75 year old farmer, who cut it on a gate while working cattle, the doctor struck up a conversation with the old man.
Eventually the topic got around to Julia Gillard and her appointment as Prime Minister.
"Well you know", drawled the old farmer, "this Gillard woman is what they call a fencepost tortoise".
Not being familiar with the term, the doctor asked him what a fencepost tortoise was.
The old farmer said."When you're driving along a country road and you come across a fence post with a tortoise balanced on top, that's called a fencepost tortoise".
The old farmer saw a puzzled look on the doctors face, so he continued to explain,
"You know it didn't get up there by itself,
it definitely doesn't belong up there,
it doesn't know what to do while its up there,
and you just have to wonder what kind of idiot put it up there in the first place"
