On the 10th anniversary of his matrix-like kick, we spoke to Harris who called the fight between the two American warriors.
"That is probably the craziest thing I've seen happen in a fight," he told SPORTbible.
"People do ask me about the Pettis move a lot but it's so unique that I don't think it gets the attention it deserves was as people now seemed to be more enamored with the big KO or submission move.
"Keeping your composure in a moment like that is something that is hard to accomplish because you can't practice that!
"What he did in the moment was a once in a lifetime strike and I'm not sure he even thought it would work. My first reaction was, 'did he just do what I think he did?'
"But the way it all played out and the excitement in the arena made for a moment that didn't need to be talked over although I think we may have all been just floored and looking for the right thing to say.
"What came out was just pure, organic astonishment!"
The kick heard around the world spilled into the mainstream garnering wide acclaim from the masses.
Pettis' kick remains etched into MMA's ultimate highlight-reel and the greatest move in the sport's storied history.
