It's Raining, It's Pouring is a traditional English nursery rhyme that has been sung by children for generations, with the familiar opening lines about rain and an old man snoring. Because almost everyone recognises the tune from childhood, short sing-song versions of it circulate widely on short-form video and soundboard sites as a quick shorthand for wet weather, bad luck or a gloomy mood. Its simple melody and instant nostalgia keep it useful for creators who want a light, recognisable cue without needing any explanation.
