Australia's Ariarne Titmus lit up the pool with a stunning victory over Katie Ledecky at the Tokyo Games on Monday, but when it comes to celebrations it was her wide-eyed, hip-thrusting coach Dean Boxall who deserved an Olympic gold.
As Titmus reached for the wall to dethrone her American rival in the 400-meter freestyle, Boxall burst into a frenzy of exuberant celebrations, punching the air and darting around the spectator gantry.
While the 20-year-old Titmus was being congratulated by her fellow swimmers, the crowd was mesmerized by Boxall as he leaped in the air, tore off his mask and screamed ecstatically, headbanging with his surfer-like hair tumbling around him.
