1995: Western Samoa beat Argentina, 32-26 to make the quarterfinals
Samoa underlined their status as a threat in world rugby with another fairytale run to the quarterfinals. Samoa finished second in their pool after toppling Italy and Argentina to book a quarterfinal showdown against hosts South Africa.
Their glorious achievement was immortalised in about 40 seconds of film, featuring in Clint Eastwood's movie Invictus.
1999: Samoa beat Wales, 38-31
Led by Blues coach Pat Lam, Samoa repeated their 1991 glory with a 38-31 victory over Wales in Cardiff, becoming the first team to topple the home side at Millennium Stadium.
2003: Brian Lima becomes "the chiropractor"
While Samoa haven't featured in the play-offs since 1995, they have still made an impact on the sport's biggest stage - one man more so than most.
In 2003 Samoa continued their proud RWC heritage, giving world champions England an early scare 35-22 in Melbourne.
But Samoa's enduring legacy from that tournament is Brian Lima's bone-crunching tackle on South Africa's Derick Hougaard, which remains the most memorable hits in RWC history.
Hougaard was on the receiving end of a hospital pass from Joost van der Westhuizen, as he stretched to collect the pass, Lima pounced on his prey like a wild animal, collecting Hougaard under the rib cage and driving him to the ground. The impact was felt right around the stadium, with the crowd releasing a collective groan.
Lima holds a special place in Rugby World Cup history, in 2007 he competed in a record fifth tournament - a feat unlikely to ever be surpassed.
