Post turtle president

While suturing a laceration on the hand of a 90-year-old man, the doctor asked his patient how he thought George W. Bush was doing as President.
The old man said, "Ya know, Bush is a post turtle." Not knowing what the old man meant, the doctor asked him what a "post turtle" was.

He said, "Did you ever drive down a country road and come across a fence post with a turtle balanced on top? You know he didn't get there by himself, he doesn't belong there, he can't get anything done while he's up there, and you just want to help the poor thing down. That's a post turtle."
