The line comes from The Christmas Song, written by Mel Tormé and Bob Wells in 1945 and made famous by Nat King Cole's warm recording the following year.

Online, the short snippet circulates each winter in memes, edits and reaction videos, where its cosy, old-fashioned tone contrasts with modern jokes or sets a festive scene in just a few seconds.
