Garbage trucks around the world play a short melody to warn residents to bring out their bins, and that everyday signal has become a recognisable sound online. Clips of the truck's chime, engine and hydraulic lift are shared in videos about city life, morning routines and cleaning, and they are often reused as a joke about rubbish, decluttering or a relationship ending. Because almost everyone has heard a truck pass their street, the sound needs no explanation and still feels funny and familiar years after it first appeared in memes and short edits.
