So a politician is talking on an Indian Reservation. He's describing his platform, talking about tax reform, welfare, yadda yadda yadda.

Now, the Indian Chief has been listening to this, so he goes up to the politician and says, "You have impressed. So, I shall bestow our tribe's honor on you. From this day forth, you will be known by our tribe as, 'Walking Eagle'."

Now, Dan Rather was covering this and went up to the chief.

"So Chief," Dan said, "Why did your tribe name this particular politician 'Walking Eagle'?"

The Chief said, "Because he's so full of shit, he'll never fly!"
