Hads Off.

Re-reading yesterday's missive, in particular the last line, I was reminded of a poser that popped up in an English lesson at school.
The teacher wrote a sentence on the blackboard and asked us to punctuate it.
It went :-

John where Mary had had had had had had had had had and had had a mistake

I wish, now, that I'd gone to school in Margate where I may have been, instead, merely given the task of spelling 'had'.

Anyone care for a stab at it?
