The Maury Lie Detector meme originates from the long-running tabloid talk show Maury, hosted by Maury Povich. A staple of the program involves guests taking polygraph tests to prove their innocence or expose a partner's infidelity, leading to the iconic catchphrase, 'The lie detector determined... that was a lie.' The meme template usually features Maury reading a card or the immediate, often dramatic, celebration or defeat of the guests involved. Since its emergence on platforms like Reddit and Twitter, the meme has evolved into a universal way to highlight hypocrisy, debunk false claims, or point out obvious exaggerations in everyday life.
