The sung line comes from W. H. Auden's 1936 poem 'Night Mail,' written about the overnight postal train crossing the Scottish border. This particular recording is a short vocal-synth rendition credited in its file tags to VocoBot, circulating as a low-view meme soundboard clip tagged 'Durr.' It has not broken out as a mainstream TikTok trend, but it survives in absurdist shitpost circles where creators prize awkward text-to-speech covers of serious literature. Its humor comes from that clash between highbrow poetry and cheap robotic delivery.
