I do belive that it's raining "Pink Elephants and Yellow Balloons".
Now, that is so much better than saying it's,"Raining Cats and Dogs!
Which, surely must be a phrase used only by the plebs.
I feel we should substitute, " It never Rains but it Pours",
with; " It's humid but I feel dry".
PS. Must make a mental note to use that phrase next time I take a taxi.
