"Better Watch Out" is the eleventh single by Ant & Dec, their first under that name (their previous singles were released as PJ & Duncan), and the first to be taken from their final album, The Cult of Ant & Dec. The song has no relation to Christmas (the title may lead to confusion with the lyrics of Santa Claus Is Comin' to Town), and is instead about a man who tries to court a girl only to get confronted by her brothers. The video starts with Ant & Dec in a barbershop.
