Torture Room
Ok to make yourself a torture room make a family and move them into a city with lots of people in the town. Turn on the move all objects cheat (by pressing holding Ctrl, Shift, C and typing moveobjects_on) then make a second floor to your house without stairs or an elevator leading up to it. Then when neighbors come to visit you pick them up and put them in your torture room and don't put anything in there like a bed or toilet. It is hilarious watching all of the people interact. Also order groceries or a pizza or call the cops or firemen etc. to get more people in there.
