Many people fall into it and get hurt and it's difficult to get them all to the hospital.
The mayor gathers the city council to figure out a solution. The smartest city councilor suggests they park an ambulance next to the hole to get people to the hospital faster. The rest unanimously agree. It has little effect.
So the mayor gathers the council a second time. The second smartest councilor suggests they close the road between the hole and the hospital so the ambulance can ferry people faster. Everyone once again agrees and again it is of limited use.
Finally they gather for a third time to take drastic measures. The third smartest councilor says they need to tear down the hospital and rebuild it next to the hole.
Finally the mayor can't take it anymore. He slams his fist on the table and yells:
"You idiots! Do you know how much moving the hospital will cost?! There's an obvious and easy solution to this problem! We fill in the hole. Then we dig a new one next to the hospital!
