The refrigerator running line comes from a long-running telephone prank built around a simple wordplay trap. A caller asks if the appliance is running, then tells the listener to go catch it, treating running as both operating and moving. As phones and voicemail became common comedy props, short recordings of the setup spread through soundboards and meme edits. Its brevity helps it survive: viewers instantly understand the joke without context, and creators can drop the familiar line into fake messages, call sketches and nostalgic prank compilations.
