"Last night I had a dream. It was the end of the world. Everything was desolate. I was the last person on earth. I found a newspaper, the last newspaper ever printed. And on it, it had a date. It was October. And I even saw the year. When I woke up, I wrote the year on this piece of paper. Can you guess the year of the Apocalypse?"
Let a year be named by the spectator. And secretly write it on that before mentioned piece of paper with a nail writer.
