A fellow stopped at a rural gas station and, after filling his tank, he paid the bill and bought a soft drink. He stood by his car to drink his soda, and he watched a couple of men working along the roadside.

One man would dig a hole two or three feet deep and then move on. The other man came along behind and filled in the hole. While one was digging a new hole, the other was 25 feet behind filling in the old.

The men worked right past the fellow with the soft drink and went on down the road.

"I can't stand this," said the man, tossing the can into a trash container and headed down the road toward the men.

"Hold it, hold it," he said to the men. "Can you tell me what's going on here with this digging?"

"Well, we work for the government," one of the men said.

"But one of you is digging a hole and the other fills it up. You're not accomplishing anything. Aren't you wasting the taxpayers' money?"

"You don't understand, mister," one of the men said, leaning on his shovel and wiping his brow. "Normally there's three of us: Me, Rodney, and Mike. I dig the hole, Rodney sticks in the tree, and Mike here puts the dirt back.

You see, Rodney called in sick today, but we still have a job to do."
