When he sits his players down for the post- match video analysis of Monday night's slipshod performance against Argentina, Sir Clive Woodward had better have sufficient loose change for the swear-box.
Not only will the exercise give the British Lions' head coach opportunity to delve into the deeper recesses of his Anglo-Saxon vocabulary, it will also show him exactly how, where and through whom a third-string Pumas team where able to master his supposedly elite band.
There are a few of the Cardiff Clowns who might want to sit themselves out of Woodward's reach. Irish tighthead John Hayes, his compatriot Gordon D'Arcy and Wales scrum-half Gareth Cooper will need to show more positional sense than they did at the Millennium Stadium.
There are several more, Lewis Moody, Danny Grewcock, Shane Byrne and Graham Rowntree to name but four, who will no doubt be pleased when the process is over.
It would be churlish not to offer mitigation, however. The squad has been together for only a week, the team on duty was nowhere near first-choice and, lest we forget the Argentinians, the opposition gave one of the best displays in its proud history.
But one man, the man in many ways, who can consider himself largely free of any blame for what developed into one of the most disappointing Lions' performances for more than a decade is Jonny Wilkinson.
The 26-year-old, he boards the plane for New Zealand today on his birthday, was not at his superstar best but if it is explanation production we're into, he could do it to an Olympic standard.
Since he dropped the goal that won England the World Cup 18 months ago Wilkinson's career has stalled as his body refused to sustain the inhuman pressure to which it was subjected.
First, within weeks of returning from Australia, his shoulder gave way and ended his 2003-04 season. Then his bicep decided enough was too much and interrupted his comeback last autumn only for his knee to play up early in the New Year. Monday's match was only his third complete game since January.
So he missed a couple of touches and one tackle. Who didn't? Playing with a miserable year-and-a-half at the back of his mind and the eyes of the world scrutinising his every movement, his was an assured performance befitting a global talent.
His place-kicking was perfect, seven goals from seven attempts, and, although none of them were particularly taxing, the penalty he made from the 'wrong' side in the last second of the match, to make the score 25-25, showed that his boot and mental fortitude have not suffered by enforced absence.
Neither has his instinct been dampened by inactivity. He was always in the right place at the right time, covering punts forward and supporting runners whenever he could. On one occasion in the opening period when Denis Hickie was isolated on the right sideline it was Wilkinson who came in and secured possession, taking a terrific blow for his pains.
His passing was typically sympathetic while the way he took the ball into contact was little short of inspiring. Wilkinson's was the decisive involvement in the Lions' only try as he drew two tacklers and off-loaded for Ollie Smith to take the ball without breaking stride.
He was not the destructive defensive force of recent years but the South Americans didn't run at him very often and he did what was asked of him - smashing hooker Mario Ledesma on to his backside in the first half and willingly assailing men twice his size.
The fact that he came through unscathed will give Woodward huge satisfaction and means the man who was the centre-piece of his world championship team should be the keystone of his Lions XV. Now that should stop him swearing.
On another note, the second notable aspect of Monday's match was the performance of the Pumas and the grace shown by their coach Marcelo Loffreda who not only teased a gargantuan effort from his men but did it without 26 of his best players.
The former Argentina international used his post-match press conference as a platform to build a case for his country's inclusion in the Six Nations.
Not only did he translate his answers without request, he did so in good humour and even apologised for using the national rugby team's finest hour as his soapbox. Woodward trotted out the same answer to four questions and had no interest in speaking with his public.
Loffreda even offered to come and play all of the championship matches in Europe, the vast majority of his players are here anyway, and pleaded for help from the International Rugby Board.
"We are not a project, we are a reality," he said. "We have shown in recent years we are very close to the top teams. This improves our image in world rugby. Maybe this is a good time to tell everybody we need help."
If Italy are worth a place in the Six Nations surely Argentina are worthy of our assistance.
