The line comes from a 1989 Milk Marketing Board television advert created to promote milk to children. It shows two boys in Liverpool kits chatting, ending with the famous exchange where one asks Accrington Stanley, who are they, and the other answers exactly. The advert became a cultural touchstone in Britain, revived Accrington Stanley's fame and is still sung as a chant by the club's supporters. Decades later the clip circulates online as a nostalgic football meme.
