Can anyone remember..............?
Years ago, possibly in the late eighties, I did a Guardian crossword which contained the following solution:
There are holes in the sky where the rain gets in.
But they're ever so small, that's why rain is thin.

I seem to remember that the whole of the clue was an anagram which led to this (Spike Milligan) poem. I did manage to get the answer, eventually, as this was in the days before Google et.al. I didn't even have a computer.

I thought it was absolute magic and have never forgotten that joy when I finally got the answer. I think it was Araucaria, although it may have been Bunthorne. Does anyone else remember this?

What is your all time favourite clue?
