"Greetings, my excellent friends, you have been chosen as the main characters of this story. And so it begins..."
"But wait! We're not ready to begin yet! You should have warned us we were going to be in a story!"
"I'm sorry, my excellent friends... but the story is supposed to be 3/4 over by now! Now the 4th author has to write everything!!"
But the 4th author was in jail for plagiarizing his latest story.
So this story will have to go unfinished, as no-one else is qualified
to complete it. Only he knows the ending.
THE END
