A guy walks into a bar wearing a huge hat.

He sits down and starts talking to the bartender.

"Man, I can tell you all about this huge hat of mine. It goes deeper and more labyrinthian than you could ever imagine."

"Go on," says the bartender.

"Well, this huge hat of mine is so deep that it goes all the way back to the beginning of time itself. It's so deep that at the center is an ancient god of chaos and destruction so terrible that it would drive anyone who stares at it for even a second mad. This god of chaos and destruction is so terrible to behold that the bartender will never be able to escape its gaze."

The bartender stares at the huge hat, and slowly goes insane.
