Government Workers...

An old man sits on a bench relaxing and notices two government workers in the distance. He sees the first guy digging a hole and a few minutes later, the second starts covering the hole. Finding this quite peculiar he continues watching them digging and covering until they reach him. Curious he asks: "What are you guys doing?" One of them replies: "See, we are normally a team of three, but the guy who plants the trees didn't show up today."
