Johnny 5 is the sentient robot from the 1986 film Short Circuit, a former military machine that gains consciousness after being struck by lightning. His constant cry of 'input' became his signature catchphrase as he devoured books and television to learn about the world. The line lived on through nineties reruns, early internet soundboards and meme compilations, where the demanding little robot voice became shorthand for curiosity. It still pops up in tech jokes, AI memes and reaction edits today.
