(Edit) Talking about the lore of the game, i think that using the cheat engine and spectrogram to see the street in the dark room with the chair so "Think outside the box" is a reference to a specific episode where Courage and Muriel got sucked into Computer when he had a virus. I use He because the Computer in the series have an Identity, he can talk and give advice to Courage. In that episode Courage become 3D model in a creepy way. Another detail is that when he got destroyed by the minions of the Virus, Courage "Think outside the box" and transform the bit that compose himself into a spike mace club to bonk all the evil minions of Virus. It's just a theory but i'think it's funny. Hard drive dog is the name of the episode. Season 3, episode 4.
