...but I thought it was worth posting anyway!

While suturing a cut on the hand of a 75-year old Texas rancher (whose hand
was caught in a gate while working with cattle), the doctor struck up a
conversation with the old man. Eventually, the topic got around to Sarah
Palin and her bid to to be a heartbeat away from being President.

The old rancher said, "Well, ya know, Palin is sort of like a post turtle."
Not being familiar with the term, the doctor asked him what a post turtle
was. The old rancher 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 rancher saw a puzzled look on the doctor's face, so he continued to
explain. "Well, you know she didn't get up there by herself, she doesn't
belong up there, she doesn't know what to do now that she is up there, and
you just wonder what kind of dumb ass put her up there to begin with."
