The line comes from Maury, the long-running American daytime talk show hosted by Maury Povich, where paternity test results became one of its most famous recurring segments. Guests would wait on stage while Povich read the DNA results aloud, and the not-the-father verdict regularly produced the show's loudest audience reactions. Clips of those reveals circulated widely on YouTube and later on TikTok, where editors reused them as a shorthand for denial and exposed lies. It remains popular because the format is instantly recognisable even to viewers who never watched a full episode.
