KEY POINTS:
1. Elton Flatley
Australia vs England 2003
There was one minute left in the World Cup final. England were leading 14-11 when referee Andre Watson contentiously ruled the Poms had deliberately collapsed a scrum.
The penalty was 30m out and 10m in from the right-hand touch - the wrong side for the right-footed Flatley. The drizzle didn't make life any easier and the pressure...
If he missed he would be remembered as the man who lost the Wallabies the World Cup.
Flatley teed the ball, took a couple of deep breaths and banged it sweetly down the middle. As it happened, an Englishman named Jonny Wilkinson drop-kicked Australia out of first place, but that shouldn't sully Flatley's effort.
2. Brian McKechnie
NZ vs Wales 1978
The All Blacks were trailing 10-12 in Cardiff with three minutes remaining when Andy Haden and Frank Oliver flew out of a lineout and the All Blacks grabbed one of the most contentious penalties in the game's history.
Substitute Brian McKechnie had to land the 37m kick.
The ground was a little heavy, the breeze stiffening and the crowd howling their protest. It didn't bother McKechnie, though, who secured the 13-12 win.
3. John Taylor
Wales vs Scotland 1971
Wales went on to clinch a Five Nations Grand Slam after beating the Scots at Murrayfield in the last minute.
Flying Gerald Davies outstripped the Scots' cover and touched down in the right-hand corner.
Openside flanker John Taylor had the toughest angle and could barely see the sticks as the gloaming descended. No problem - Taylor kept the dream alive with a miracle kick and Wales went on to make history.
4. Peter Brown
Scotland vs England 1971
The Scottish No 8 and brother of the better known Gordon used to turn his back on the ball as he walked to his mark.
In 1971 Brown stunned Twickenham when he landed a conversion from wide on the left in the dying minutes to see Scotland home 16-15. BBC commentator Bill McLaren described the kick best when he said: "It wobbled over the bar in an inebriated fashion."
5. John Eales
Australia vs NZ 2000
The All Blacks led 23-21 going into injury time in the Cake Tin's inaugural test.
Craig Dowd conceded a penalty and the Wallabies had a last chance. Regular kicker Stirling Mortlock had been replaced so it fell to skipper John Eales to bang it over from 40m.
Eales loved the responsibility and swung his giant right leg to make a magnificent contact and break four million hearts.
6. Allan Hewson
NZ vs South Africa 1981
The results of this series have been largely forgotten, which is a shame for Allan Hewsonas the final test at Eden Park was probably his finest hour.
The score was tied at 22-all after Ray Mordt slipped in at the corner with 79 minutes on the stadium clock.
But referee Clive Norling played an inordinately long injury period, in which time New Zealand were awarded a penalty 10m outside the 22.
Hewson, with the series split at one test each, ignored the flour bombs and nailed the kick.
7. Neil Jenkins
Wales vs England 1999
Everyone remembers the try scored by Scott Gibbs to bring Wales within a point of England in the dying minutes.
But as brilliant as that try was, Jenkins still faced a tricky conversion from 15m to the right of the posts.
It looked relatively simple but was in that horrid position where it was quite missable.
Jenkins revealed afterwards that he was unusually nervous but he never let that show on the pitch.
8. Don Clarke
NZ vs British Lions 1959
The Lions played all the rugby and scored all four tries in this opening test of the series but it was the boot of Don Clarke that played the most critical role.
Clarke kept booming them over from everywhere and, with the Lions leading 17-15 and only two minutes to go, he kicked his sixth successful penalty to wrap things up.
9. John Callard
England vs Scotland 1994
Scotland defied expectation and led this opening Five Nations test 14-12 with one minute left after Gregor Townsend dropped a monster goal. A famous win was in sight until England were wrongly awarded a penalty after their own player, Rob Andrew, was handling in a ruck.
The Edinburgh crowd went hostile - with Will Carling on the pitch they were already fairly het up - but Callard banged it true and England rushed to the changing rooms.
10. Grant Fox
NZ vs Lions 1993
The Lions were only a few minutes from securing a surprise victory in the first test of the series until No 8 Dean Richards was deemed to have handled in a ruck. Trailling 18-17, the All Blacks knew the penalty was their last chance and Grant Fox duly did the honours with a superb effort from 40m. New Zealand won the series 2-1 and Lions supporters still moan about the penalty to this day.
