Brian O'Driscoll and Paul O'Connell scribed their names in Irish folklore during the 2009 RBS 6 Nations as both inspired the Men in Green to their first Grand Slam for 61 years.
O'Driscoll was skipper, racking up four tries including crucial scores against England and Wales, and was named player of the tournament while O'Connell was colossal in the pack and was rewarded for his form with the captaincy for the subsequent British & Irish Lions tour to South Africa.
It all could have ended on the sourest of notes for Ireland however, had Stephen Jones not seen his last-gasp penalty drop just short in the final game which ensured Ireland edged past Wales 17-15 and completed their clean sweep.
In the most thrilling of finales, Jones had appeared to rain on Ireland's parade as his 76th minute drop goal handed Wales a 15-14 lead, only for opposite number Ronan O'Gara to respond in kind, two minutes later.
O'Gara finished the competition as the top points scorer and he helped Ireland get their campaign under way on gameweek one, racking up 15 points as his side clinched a rare victory over France in Dublin.
Trailing to an early Imanol Harinordoquy try, Ireland stormed back with scores from Jamie Heaslip, O'Driscoll and Gordon D'Arcy to secure a 30-21 win.
Warren Gatland's men, who had won the Grand Slam the previous year, continued their impressive form as Leigh Halfpenny and Jones inspired a 23-15 win over England in Cardiff.
France got back to winning ways with a 22-13 win over Scotland while Ireland signalled their intent with a thumping 38-9 win in Rome - Luke Fitzgerald notching two tries and O'Driscoll chalking up his second of the competition.
Wales then went in pursuit of equalling the most RBS 6 Nations wins in a row but came unstuck against France as Thierry Dusautoir and Cedric Heymans crossed in a 21-16 victory while Scotland got their first win of the competition, Simon Danielli and Scott Gray helping their side to a 26-6 victory over Italy.
England then headed to Dublin, hoping to get back to winning ways but O'Driscoll was in unrelenting form, scoring his side's only try of the match and adding a drop goal to boot.
Delon Armitage's 78th-minute score proved to be in vein as Martin Johnson's England slipped to a second straight defeat, going down 14-13.
But back at Twickenham, England did give their fans something to cheer about in week four, thrashing France 34-10 after racing into a 29-0 lead at half-time with Mark Cueto getting things off to a flying start with a first-minute try.
It was Les Bleus' turn to vent their frustration at the start of the final weekend, racking up seven tries in a 50-8 win over Italy and Riki Flutey grabbed his fourth of the competition to finish joint top try-scorer with O'Driscoll in England's 26-12 victory over Scotland.
Wales then welcomed Ireland to the Millennium Stadium, knowing that they would need to win by more than 13 points to retain their RBS 6 Nations title while the Triple Crown was also up for grabs.
And it still looked possible after taking a 6-0 lead in at the half-time interval, only for quickfire tries from O'Driscoll and Tommy Bowe to hand Ireland a 14-6 advantage.
Two Jones penalties trimmed the deficit however and he handed Wales the lead with his drop goal, only for O'Gara to hit back before the late penalty drama.
Jones lined his effort up from just inside the Ireland half but didn't have the distance to hand Declan Kidney a Grand Slam in his first RBS 6 Nations in charge.
In doing so Ireland became the second team to win the Grand Slam when playing three away matches, repeating Wales' 2005 ground-breaking feat.
