Obama: Post-turtle

While suturing a cut on the hand of a Texas Rancher whose hand had been caught in a gate while working cattle, the doctor struck up a conversation with the old man.
Eventually, the topic got around to Obama and his bid for the presidency.

The old rancher said, Well, ya know, Obama is a 'post turtle'.

Not being familiar with the term, the doctor asked, 'What is a post turtle'?

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 he didn't get up there by himself, he sure doesn't belong up there, he doesn't know what to do while he is up there and you just wonder what kind of an idiot put him there in the first place.'
