There would have been plenty of sore Irish heads on Sunday morning.
Joe Schmidt's Ireland team rounded off a fantastic Six Nations campaign by beating the previous winners, England, at Twickenham, on St Patrick's Day. It doesn't get much better than that.
Despite a sticky start to the tournament against France, the Irish proved they were more than worthy winners of the Grand Slam with a very professional performance against England.
Although much has already been made about the display of Eddie Jones' side, Ireland were certainly made to work hard for their victory.
And the eruption of emotions at the final whistle justified that too. Becoming just the third Ireland team to secure a Grand Slam is a mighty achievement.
But extra credit deserves to go to flanker Peter O'Mahony, who, having just been given his winners medal on the hallowed Twickenham turf, decided he give the precious piece of memorabilia to a superfan in the crowd.
In fairness, it isn't just any superfan, though.
Jennifer Malone made headlines two years ago when the image of her consoling Waterford's Pauric Mahony after their Gaelic football defeat by Kilkenny in the All-Ireland semi-final replay was widely shared on social media.
Well Jennifer has gone viral again after O'Mahony spotted her in the crowd and graciously gave her the medal he had literally just picked up.
Not only that, the 28-year-old also posed for photos with Jennifer and the Six Nations trophy.
It was all documented on Twitter by Jennifer's sister Rachel.
What an amazing gesture. O'Mahony is an absolutely top bloke!
It's good to know there are still some genuinely nice people at the very elite level of sport.
O'Mahony has certainly recovered from the ignominy of being dropped for the second and third Lions Tests in New Zealand last year, having captained the team to the first Test defeat.
He started every game in this year's Six Nations and there's little doubt his consistency proved crucial to Ireland's latest triumph.
