The whole of Australia is absolutely buzzing for Ariarne Titmus after she won Olympic gold in the women's 400m freestyle.
But it seems no one was more happy than her coach.
Titmus' swimming instructor has become an instant internet sensation for his wild celebrations after the race in Tokyo.
The bloke, donning a yellow Australia training jersey, was seen running up and down the sidelines within the arena screaming his head off.

Roaring, punching the air and even shaking the surrounding barriers, it didn't take long for the coach's complete and utter meltdown to make its way onto social media where he immediately became meme gold dust.
The passionate reaction went viral, of course, with countless social media users sharing the incredible footage.
"He's putting on a show like Mick Jagger of the Rolling Stones," one commentator said on an American broadcast of the Olympics.
The dude was pretty fired up - what passion!
