While sewing a cut on the hand of a 75-year old Texas rancher, whose hand was caught in a gate while working cattle, the doctor struck up a conversation with the old man. Eventually the topic got around to Sarah Palin and her bid to be a heartbeat away from being President.
The old rancher said, "Well, ya know, Palin is a post turtle."
Not being familiar with the term, the doctor asked him what a post turtle was.
The old rancher said, "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 rancher saw a puzzled look on the doctor's face, so he continued to explain. "You know she didn't get up there by herself; she doesn't belong up there; she doesn't know what to do while she is up there; and you just wonder what kind of dumb ass put her up there to begin with."
