Today marks the 50th anniversary of the introduction of Prime Minister's Questions to the democratic process in the United Kingdom and so it seems only right to remark on the grey streaks spotted in the hair of the present incumbent.
This is not to trivialise PMQs since its participants need no help from outsiders iIn this regard but to choose on this birthday from the very short list of subjects of interest which actually occurred.
As ever it was meant to be different .The disemboweling of Dave had been on the menu following his hanging and drawing over Europe on Monday by the many Tory backbenchers who suspect that despite attending Eton he has friends of a non-British variety.
Half of his party had even come back early from dinner for the chance to give him a good kicking over his failure to sort out Johnny Foreigner, not to mention the hump most of them had at not getting on to the Government payroll because of Dave's dalliance with the Lib-Dems.
Now he was due in front of them again before setting off to Brussels for the latest last-ditch meeting of European leaders working out which country is next to go bust.
It was therefore perhaps no surprise that Dave's manly mane should find itself showing signs of political pressure as he turned up in the place of his most recent humiliation for a second unwelcome helping of verbal violence.
He looked unsuprisingly strained as he took his seat for the gala performance. In front of him his enemies in the Labour Party, behind him his enemies in the Tory Party and beside him Nick Clegg. And then he stood up -- and his side cheered and cheered and cheered.
Had they sobered up since Monday night? Had they been told off at home? Had Dave and his enforcers now got all their names and addresses?
Whatever the reason he stood somewhat stunned as the Tory benches exploded with the sort of enthusiasm normally only seen when the Government adopts the latest campaign from the pages of the Daily Mail.
Equally stunned was the Leader of the Opposition who had clearly entered the chamber on a high having spent 48 hours watching the Tory Party doing what Labour excels in -- cutting its own throat.
Fervent Ed-watchers will be forgiven if they find the references to the hair colour of the PM irrelevant to today's proceedings but that is surely only because little mention is made of the grey spot painted onto the front of his hair to give him more gravitas.
He had sat desperate to be let at his foe, excitedly clutching his papers packed with the quotes that showed the Prime Minister was not just out of touch with his party but with his coalition, not to mention the country.
Had not half his party demanded a new deal on Europe and had not the Deputy Prime Minister ruled this out ."Who speaks for the Government?" Ed demanded to know.
"Well, not you", was the clear answer from the Tory back benches as they made it clear that Dave-devouring is a sport restricted to fully paid up members of their party and not open to the great-unwashed opposite.
Ed and his advisers had clearly not factored Tory tribalism into their running order and once again the Tory leader sprang free from the trap.
Indeed newly emboldened Dave said he and his Deputy did share many of the same views leaving Nick with that hapless grin that marks so many of his non-speaking performances at the weekly event.
Ed was "a complete mug" on Europe charged the PM as his own side looked likely to have collective heart attacks of over-excitement. It was as if Monday had never happened. Dave sat down in relief .Ed sat down in confusion.
It may be worth pointing out that this year not only marks the 50th anniversary of the launching of PMQS but also of Grecian 2000. This is not, as you might think, a reference to the Greek sovereign debt but to a hair product. Dave and Ed may want to enquire further.
