Pong

[[A stick figure asks another]] So what do we do if video game AI opponents become smart enough to question the "Matrix" into which we've put them? [[A Pong paddle thinks]] Wait a minute! None of this is real! I can see through the world! I can see the code! I AM THE ONE! [[The pong ball is moving towards the paddle]] [[The pong ball slows down]] [[The pong ball stops in "midair"]] [[The pong ball drops towards the bottom of the screen]]

Following this, the pong paddle went on a mission to destroy Atari headquarters and, due to a mixup, found himself inside the game The Matrix Reloaded. Boy, was THAT ever hard to explain to him.
