You’re on a train
You’re on a train. The man across the aisle is reading a book and he keeps smiling and occasionally snorts with laughter. It’s one of those times when someone is reading something funny and just can’t hold it in. Something is really tickling him.
The cover of the book is nondescript but you want to know what’s so funny, so you make as if you’re standing to stretch your legs and you walk around behind him and glance over his shoulder to try and catch a glimpse of the text. The book is blank.
That’s how you discover YOU’RE IN THE TRUMAN SHOW. It is Season 2 and the ratings are in the toilet.
