The line comes from Mel Brooks' 1974 comedy Young Frankenstein, released in Italy as Frankenstein Junior. In the graveyard scene, Frederick complains about his work and Igor, played by Marty Feldman, replies that it could rain, prompting an immediate storm. The Italian dub turned that exchange into the catchphrase Potrebbe piovere, quoted for decades by Italian audiences. Online it survived as a reaction clip for tempting fate, shared whenever someone says things cannot get any worse and reality quickly proves them wrong.
