There were only 12.2 seconds on the clock when the Hoops midfielder fired the home side ahead to break the record of fastest SPL goal.
Ironically, the record was previously held by Anthony Stokes who set up the Scotland midfielder for his opener in what turned out to be an exciting 4-3 victory for the champions.
Commons was 0.2 seconds quicker than the Irishman who set the record during his time at Hibernian.
"It was crazy," said Commons, speaking to Celtic's official website. "First of all, Mikael (Lustig) played it up front, Hoops (Gary Hooper) got a flick on, I found myself in space on the edge of the box and Stokesey played a great ball through to me.
"I took one touch and smashed it in. It was one of those crazy things that usually never happen.
"I don't think half the fans were even in the stands yet. The manager wasn't even in the dugout so it was a bit of whirlwind.
"Aberdeen hadn't touched the ball yet but we play that way from kick-off, we go forward and try and put them under pressure in the opening couple of minutes.
"But for it all to fall into play and for me to have a shot on the edge of the 18-yard box was crazy luck.
"It beat Stokesey's record. He was telling me afterwards that he was sure I'd beat him so I think he's a little bit wounded now."
