One evening in the late 1800s, a lighthouse keeper named John Herman was drinking, as he usually did, when he decided to play a prank on his assistant. Herman locked the assistant in the lantern room and left him there.
When the assistant managed to get out of the room, he found himself all alone in the lighthouse.
