My Fatal Mistake!
Storyline: A man is bitter because he has been replaced by a computer and must take a job servicing it. It is ensconced in an air-tight clean room with a door that is opened after fifteen minutes allotted for servicing purposes. When the man enters the room, he gets the idea to sabotage the machine so that it will make mistakes and he can get his old job back, but he damages the circuits that allow the machine to open the door after the fifteen minutes of oxygen are used up.
