While suturing a laceration on the hand of an 80-year-old grizzled Queensland cow cocky (whose hand had caught in a gate while working cattle), a doctor and the old man were talking about Mark Lathams' possibility of being Prime Minister.

The Cocky said, "Well, ya know, Latham's one of them 'post turtles'."

Not knowing what the old man meant, the doctor asked him what a post turtle was.

The old man said, "Well, when you're driving down a country road and you come across a fence post with a turtle balanced on top, that's a post turtle."

The old man saw a puzzled look on the doctor's face, so he continued to explain, "You know he didn't get there by himself, he doesn't belong there, he can't get anything done while he's up there, and you just want to help the poor dumb bugger get down before he hurts himself."
