Actually, I do not think that this applies to Nancy Pelosi, about whom the original email joke was told. I consider Pelosi profoundly misguided, but I think she has skills.
The joke does, however apply to Harry Reid ... so I changed it.
While suturing a cut on the hand of a 75 year-old Nevada rancher whose hand was caught in a gate while working cattle, the doctor struck up a conversation with the old man. Eventually the topic got around to Senator Harry Reid and his elevation to Senate Majority Leader.
The old rancher said, "Well, ya know, Harry is a post turtle."
Not being familiar with the term, the doctor asked him what a "post turtle" was.
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 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 dumb animal get down."
