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 bastard get down."
