Kill a fireman, policeman, or serviceman
Call the fireman, policeman, or serviceman over to your house. When they first open your front door, build a wall so that they cannot go into your house any further. Build a wall behind them so that they cannot leave and are stuck. This may be difficult with a policeman because he can run very fast. They will die in their "cell" after falling asleep standing up, urinating on the floor, and doing their usual pre-death routine. It will take longer than a normal Sim. When you trap a baby deliverer because both the baby and the deliverer will die. Note: You will lose your ability to buy or construct if you trap a baby deliverer. This should be the last person you trap and the game should not be saved after you trap him.
