This week saw something that we all love in sport; pure, unfiltered passion. Not in the AFL either. When Ariarne Titmus shocked the world to claim Gold in the 400m Women's Final at the Olympics in Tokyo this week, the icing on the cake was the celebration.

Though 'Arnie' looked spent, her coach Dean Boxall had plenty of energy to celebrate in style. While some in the saltier corners of the earth (read: United States) tried to rain on the parade, the bottom line is that this was an outpouring of emotion.

It's easy to forget that it's not just the athletes who give their heart and soul to a cause, the coaches are just as devoted. Boxall's celebration was the pressure valve releasing, his pride, relief and happiness all boiling over.

By his own admission, Boxhall 'lost it' when he channeled the Ultimate Warrior in his now famous celebration. This doesn't, however, diminish, overshadow or steal the limelight away from Titmus' incredible achievement.

An Olympic Champion at just 18-years of age, anyone involved in this incredible feat has every right to 'lose it' if they want. It's that sort of passion that we love to see in sport and in our athletes, coaches and even administrators.

With all of that in mind, we take a look at some of the most memorable outpourings of emotion in the past two decades of AFL footy.

2. Tom Boyd Arms Wide Open

Much maligned during his brief AFL career, unfairly it must be said, Tom Boyd delivered on the grandest stage of all. With the Bulldogs playing in their first Grand Final in over 60 years, he timed it perfectly.

Apart from taking a handful of contested grabs to help the Dogs build momentum in the second half, it was his iconic goal from the centre square that stole the show.

An absolute bomb that the crowd willed home, his raised arms celebration while his team mates mobbed him has become an iconic moment.

Besides Boyd's joyful scream as he celebrated, the outpouring of emotion the goal triggered from Dogs fans is what lives long in the memory. It was perhaps this moment above all the others during that game when Bulldogs fans really started to believe.
