The Polynesian-themed dance, complete with palm trees surrounding the stage, was a perfect showcase for Fisher's talent and Arnold's stunning choreography.
One of the most impressive aspects of the song came during Lin-Manuel Miranda's verse, during which Jordan and Arnold added modern dance elements to what had been a largely traditional foxtrot, giving it a unique twist.
While deviating from tradition can often be dicey territory for contestants and pros, each of the judges acknowledged how truly flawless the performance was.
"Your talent is so undeniable," Carrie Ann Inaba marveled after the performance. She actually singled out the number's modern breakdown in the middle of the song, and said that, even though she felt it went on a little too long, "I can't take anything away from you for it, because you delivered it so perfectly."
The typically critical Len Goodman also referred to his usual distaste for adding non-traditional dance segments to classic styles, but said that Fisher's perfect foxtrot form was so good "I can forgive anything."
Bruno Tonioli added that Fisher and Arnold's routine is "how you would dance foxtrot in the 21st century," calling out the pair's ability to pull off the classic dance form while incorporating unusual syncopations into the choreography."
When asked if dancing to his own song added any pressure, Fisher hesitated before admitting, "I forgot that I danced to my own song, I'm not gonna lie. That's kinda crazy."
The pair couldn't contain their excitement as each of the judges held up their 10 paddles, and they were left speechless by the perfect score.
ET's Keltie Knight caught up with the couple after the show, where they admitted the reality of the impressive feat "hasn't set in yet."
"Since the moment it happened, it's been what, like, 20 minutes? And every time we look at each other we go, 'Oh my god! Oh my god'!" Fisher bgushed.
"Yeah it's pretty crazy and it's pretty cool, because I've never gotten the first perfect score of any season that I've been on," Arnold shared. "So this is a first for both of us and it's really cool that we get to have that together because it's a big thing."
"Our goal is to hopefully get more of those," Fisher added.
