The phrase became famous from the 1988 comedy The Naked Gun: From the Files of Police Squad, where Lieutenant Frank Drebin, played by Leslie Nielsen, tries to disperse onlookers in front of an exploding fireworks factory. His calm insistence that everything is fine became a shorthand online for obvious denial. The clip spread through meme edits, reaction videos and soundboards, and is still used whenever someone tries to pretend a very visible mess is not happening at all.
