As the cannon went off following Oliver Bjorkstrand's game-sealing tally, Arnott mimicked being blasted by the cannon, flying through the air and landing on his backside in a moment captured by Fox Sports Ohio cameras. The celebration drew attention across the hockey world and beyond, with even CBJ captain Nick Foligno tweeting the video while calling it it the "greatest thing I've seen in a while."
For Arnott, it was a moment to remember, but here's where you might be surprised. Given the expert timing and staging, you'd think the moment had to be rehearsed, staged or otherwise perfected.
But that's not the case.
"I didn't plan it," he said. "This one, I was just like, 'I'm going to step up and do this thing.' I'm proud of myself for the execution. I didn't die, but it looked like I did. I'm happy with it."
The Cannon Crew and members of the Papa John's Goal Patrol have been celebrating Jackets goals in style for years, with their shenanigans captured by the FSO camera strapped to the railing that the TV network cuts to after each Jackets goal to show the blast.
From choreographed dances to posed photos to one member last year shoveling bread into his face after an Artemi Panarin goal -- OK, that was Arnott, too -- the background of the cannon blast is a blank canvas Arnott and his fellow members of the promotions teams have been more than happy to fill.
But this celebration stood out among some other classics, and it was born of Arnott's dedication to the show. A former member of the Marching 110 band at Ohio University as well as a participant in high school theater, Arnott has some ham in him, not to mention knowledge of how to make things work on a stage.
For example, for this celebration, the key was to execute a pratfall that not only looked realistic but didn't result in bodily harm upon landing. Consider both objectives satisfied.
"I'm used to throwing my body around for the show," he said. "It surprisingly didn't hurt. I was really happy. Someone mentioned that was an A-plus pratfall. I remembered rule No. 1 about a good pratfall is landing on your butt. I was watching it and was like, 'Wow, I landed pretty well.'"
The reaction since has been impressive. It's a moment that seemingly was born for Twitter and Instagram, and pages across the internet have picked up the video. (Also amusing: The celebration after the Jackets' first goal Tuesday, in which Arnott was revived from the cannon fire.)
