Before you proceed any further, here's your SPOILER warning. This video contains a story moment that is best experienced by playing the game. Seriously, if you have the opportunity to play the game tomorrow, next week, or even a year from now, leave this story now.
For those of you who don't care and just want to see how clever Naughty Dog can be, click play and enjoy the moment. I won't give any other build up for it other than it shows us that Naughty Dog has a great sense of and finds a way to kind of break the fourth wall in the process. It's a hell of a moment in the story that actually holds a lot of meaning by the time the credits roll.
