Murrayfield misery for England?
"In international rugby, passion is very important. It is a warrior sport, you are searching for the toughest competitors who will put their bodies on the line - players who inspire the nation." Andy Robinson, Scotland head coach, talking to BBC Sport
It's a fantasy many of us have indulged in: the spurned employee, handed the chance to put one over his or her old boss. The chance to say, "things are going just fine, thanks, how about you?"
Just as Andy Robinson could be forgiven for saying the very same thing if his Scotland side rumble England on Saturday: the RFU's worst nightmare, hand outstretched, eyes narrowed and wearing just the ghost of a smile.
Murrayfield is where it all started to go wrong for Robinson as England coach - an 18-12 defeat in 2006, the start of a record-equalling run of seven defeats on the spin. Looking back, it's easy to come to the conclusion the RFU bigwigs got it right.
But Robinson will point to battles lost in the boardroom, the lack of access to players, the lack of control full-stop. All stuff Martin Johnson has been given - and if England come a cropper in Edinburgh, all stuff the critics will say hasn't improved things one jot.
Still, Robinson himself is calling it just another game, and Phil de Glanville, who played with Robinson at Bath and under him when Bath won the Heineken Cup in 1998, insists Scotland's coach won't be allowing revenge to obscure his vision.
"Most of the players and management weren't around when he was there and it wasn't their decision to sack him," De Glanville told BBC Sport. "He won't be eaten up by it.
"He'll keep it in perspective and be wary that he wants his Scottish players to focus on the technical aspects of the game and not get too fired up in the extraneous stuff -
the sort of stuff Jim Telfer's been coming out with this week."
Telfer, who led Scotland to a Grand Slam in 1984 and was Ian McGeechan's assistant coach for the celebrated 1990 clean-sweep, reckons Scotland are a better team than England and that, "in terms of rugby philosophy, Andy Robinson and Martin Johnson are about as far apart on the spectrum as it is possible to get".
De Glanville says that's just Telfer being Telfer and that his two old team-mates have more in common than many might think.
"People forget that Andy Robinson was effectively the head coach when Martin Johnson won the World Cup with England in 2003," said De Glanville.
"Clive Woodward was the figurehead, but the majority of the coaching was led by Andy at that time. Every coach makes mistakes early on in terms of applying the right approach, and Johnno's only criticism of Robbo might come back to that.
"But in certain aspects of rugby philosophy I'd have said they were very close. Andy's vision of how the ball it should be moved around is probably a bit more ambitious than Martin's, but in terms of understanding the importance of set-pieces and of the forwards and building the momentum of the game, they're very similar.
"I don't perceive any individual animosity, I think they've got a fairly healthy respect for each other. The only other side of it is that Johnno was brought in after Andy, although Brian Ashton was in between, so Andy might be thinking, 'is Johnno a better coach than me?'"
De Glanville doubts Robinson, a fiercely patriotic Englishman as a player, will attempt to summon the spirit of 1990 in the Scotland dressing room in an attempt to inspire his troops. However, Robinson has hinted otherwise, stating that "whatever it takes, we will use".
"I will leave it to others to explain the passion I bring to the Scotland team," Robinson told BBC Sport before the tournament started. "I would like to think it isn't questioned."
It isn't, according to scrum-half Chris Cusiter: "Andy is as desperate for the team to win as any of us Scotsmen. There is not one player in the Scotland squad who has questioned why Andy is in charge of Scotland. We trust him implicitly."
Which is more than you can say for the RFU. If Scotland do beat England on Saturday, the tide of criticism which has intermittently been lapping at Johnson's feet these last few months will become a wave.
Murrayfield, where it all started to go wrong for Robinson and where things fell apart for Ashton, could, in years to come, be regarded as Johnson's Bannockburn, too.
