As English is not my first language, when first time I heard “Its raining cats and dogs” – I got stuck in place. It took time for me to understand that I am dealing with an idiom – the falling down from heaven various cats and dogs overfilled my imagination!!!

Recently I searched for the same idiom but in other languages, and here the funniest versions which I have found:
