The line comes from The Truman Show, the 1998 film starring Jim Carrey as Truman Burbank, a man whose entire life is broadcast on television without his knowledge. Truman repeats the greeting to his neighbours each morning, unaware cameras are watching, and delivers it again in the film's famous final escape scene. The quote became one of the movie's most quoted moments, circulating as a reaction clip and farewell meme online, where its polite, all day coverage still works for sign offs, endings and dramatic exits.
