The term "6.9 joke" is a vulgar joke that plays on the similarity between the number 69 and the sexual position of the same name. The joke is typically structured as a question, "What is 6.9?" followed by the punchline, "A good thing ruined by a period". The joke has gained some notoriety due to a viral TikTok video that appeared to show actress Anne Hathaway telling the joke to comedian Jon Stewart on "The Daily Show". However, this video was later revealed to be fake and created using artificial intelligence.
