“It's raining cats and dogs”in other languages

Same idea, different pictures

English rains animals, a phrase made popular by Jonathan Swift in 1738; nobody knows why cats and dogs. Dutch rains pipe stems, het regent pijpenstelen, the long thin stems of old clay pipes.

French rains halberds, il tombe des hallebardes, long spears falling point first. It also has a cruder farmyard version: il pleut comme vache qui pisse, it's raining like a cow peeing.
