My Uncle Works at Nintendo is one of the oldest and most pervasive urban legends in gaming culture, dating back to the late 1980s and early 1990s. Before the internet made fact-checking instantaneous, children would often invent high-ranking relatives at Nintendo to gain social status or justify outrageous claims about secret characters, unreleased consoles, or hidden levels in games like Super Mario Bros. or Pokémon. The phrase has since evolved into a sarcastic retort used to mock someone making unsubstantiated or clearly false claims about upcoming media or 'inside information.' It serves as the ultimate symbol of the 'trust me bro' era of gaming misinformation.
