2 men are working for the municipality.
One of them is digging a hole and the other one fills it up again shortly after wards. They continue doing this for several times.
A pedestrian observes their work for a while and finally, he asks one of them: "Can you tell me why you dig holes and your colleague fills them shortly after wards again?"
One of the officials answers: "Normally there is a third colleague who plants the trees but unfortunately he is ill at the moment!"
