In Metal Gear Solid for the original PlayStation, there was a boss fight against Psycho Mantis, who was a psychic who could predict your every move. The fight was literally impossible. It didn't matter what you did, he always had the perfect counter. Of course, he would taunt you about his ability to predict your every move.
My brother and I were absolutely stuck on the fight for what seemed like forever. At one point, a character mentions that he's reading your controller and you can block him by switching to the 2nd control port. So you physically unplug your PlayStation controller and plug it into the other port. Then he reacts by not being able to read your moves, and you can actually fight him "fair".
It blew my mind the first time it happened. I can't remember a video game ever breaking the forth wall like that before.
