The line comes from The Elder Scrolls V: Skyrim, released in 2011 by Bethesda, where town guards say it after investigating a noise and finding nothing. Players shared clips of guards shrugging off arrows and dead bodies, and the quote became shorthand for broken stealth AI. It spread through gaming videos, compilations and reaction edits on YouTube and social media, and is now used far beyond Skyrim for any moment where someone dismisses something painfully obvious.
