Cruden gets nod for All Blacks
Strictly that has happened only twice, in 2009 against the Wallabies and 2013 against France with the chance of another sequence set up against England at Twickenham on Sunday.
Back in 1996 the All Blacks beat the Springboks four times but they also lost another test against our greatest rival. Those were heady times as rugby bounced around in its professional infancy.
It's extraordinary to recall that half of the All Blacks' 10 tests that year were against South Africa as they duelled in five of their last six tests for the year.
They met at Lancaster Park, then Newlands, Kings Park, Loftus Versfeld and Ellis Park in a torrid sequence until the All Blacks could finally claim their first series victory in South Africa.

The only respite for the sides came after Andrew Mehrtens kicked five penalties on his home track to give the All Blacks a 15-11 margin.
A detour through Brisbane was the interruption before the All Blacks won 29-18, 23-19 and then 33-26 at Loftus Versfeld to nail the series.
That was four in a row before the Boks retrieved some credit with a 32-22 win at Ellis Park.
We had to wait until 2008 for another four tests against the same side with all sorts of sub-plots as Robbie Deans moved his coaching talents to the Wallabies. Cripes, first game and the Yellow Devils waltzed home 34-19 in Sydney.
It was a false dawn for the Wallabies as they lost the other three tests that year and then all four in 2009. There was a single-point scrape in Sydney before the All Blacks iced the series with a 32-19 victory as the teams sushied in Tokyo.
The All Blacks' chokehold on the Aussies continued through 2010 with another one-point margin in Sydney before their luck ran out in Hong Kong with the concession of a final-minute converted try.
France were the last victim as the All Blacks struggled and shone in a variety of conditions last year.
The hosts were grateful at Eden Park when visiting No 8 Louis Picamoles dropped an awkward pass for a converted try to bring the charging tourists level with time almost up.
The All Blacks shut them out in Christchurch and held on for a 24-9 victory in a disjointed test in New Plymouth before the sides met for the final time in Paris.
It was a tough old scrap with the inventive spark of left wing Charles Piutau the difference in the 26-19 struggle.
Now for Twickers and the opportunity to slide the knife between England's ribs for the fourth time this season.
Forget the chat about any psychological edge for the World Cup next year. Strong teams tune their minds and focus to their next mission: Twickers is that target, nothing else.
