The Fire Alarm

Homer is at work when he notices something is a little off. Turns out the piece of paper he was holding is on fire. As he tries to put it out, he only spreads the flames further. The fire alarm goes off and everybody is in a panic. Before you know it, the entire plant is on fire. Homer makes his way outside, but for some reason he barricades the door locking everyone else inside burning to death as they scream for help. Shortly after it seems like the entire plant died and Homer is clueless as to why.
