While suturing a 70-year-old Texas rancher whose hand had been caught in a gate, the doctor and the old man were talking about George W. Bush being in the White House.
The old Texan said, "Y'know, Bush is a post turtle".
The doctor asked what a post turtle was.
The old man said, "When you come across a fence post with a turtle balanced on it upside down, that's a post turtle." The old man saw the puzzled look on the doctor's face, so he explained: "You know he didn't get there by hisself, he don't belong there, he can't get nothing done while he's there . . . and you just want to help the poor bastard get down."
