While suturing a laceration on the hand of a 70-year-old Texas rancher (whose hand had caught in a gate while working cattle), a doctor and the old man were talking about George W. Bush being in the White House.

The old Texan said, "Well, ya know, Bush is a 'post turtle'."

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

The old man 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 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 doesn't know what to do while he's up there, and you just want to help the poor stupid guy get down."
