So, some 20 years ago the Irish broadcaster RTE was filming a news story in a pub. Totally unrelated to the topic of the story, the cameraman caught the image of a baby taking a belt out of a pint of Guinness. Recently, the footage of the what has been called "The Pintbaby" began the rounds on the internet, and of course, it went viral. The Pintbaby - named Stephen - by the way, has since been tracked down. Ciaran McCauley, of the BBC News NI, tells the story here.
