My pick is STILL the semi final in the '99 Rugby World Cup. I recall following that world cup, and South Africa being pretty well favoured to take the cup. Whilst watching the game I remember in the telecast how loud the crowd was (which has subsequently put going to see a game of Rugby Union at Twickenham on my bucket list).
The game was played out EPICLY and in overtime Larkham pulled this off. (which was apparently his first ever field goal (not first professionally, first ever in a game of football apparently))
Hardware, that Brocky vid is a good video of a man clearly confident in his own capacity!. As pointed out even by the commentary team, those slicks were a few laps early... put on a great show for the crowd (and youtubers many years later)!
