George Costanza's answering machine greeting comes from Seinfeld, the long-running American sitcom built around Jerry Seinfeld and his friends in New York. The joke works because George turns a routine voicemail into a self-important little performance, complete with a theatrical greeting and a wait for the beep. As Seinfeld clips spread through reruns, DVDs and online video, the message became a favourite shorthand for the character's vanity and anxiety. Today creators reuse it to signal a missed call, an awkward excuse, or pure nineties sitcom nostalgia.
