Even the most casual of Flames fans are familiar with the footage.

In a clip that’s been shown on Hockey Night in Canada for the better part of three decades, a jubilant Theo Fleury is shown racing towards centre ice in celebration, ducking past his teammates, dropping to his knees for a series of fist pumps before rolling onto his belly and back before slamming his butt into the boards with feet in the air.

A mobbing by fellow Flames ensues.

You know the sequence.

What a generation of hockey fans likely don’t know is the scenario, the end result, or the controversy involved.

It wasn’t a series winner, nor was it necessarily popular at the time.

What it was, will forever be a delicious snapshot of the last Battle of Alberta playoff showdown.

As grainy as the video is from 31 years ago, it perfectly encapsulates the over-the-top emotion that made the provincial punch-up as legendary as it was in its heyday of the 80's and early 90’s.

"I was really hurt during the series — I had a second-degree shoulder separation, a second-degree tear of my MCL, and I was getting shot up with Novocaine all series," explained Fleury, now 53.

"I scored 51 goals that year but I hadn’t scored a goal in the whole series, so the pressure was mounting. I still hadn’t had an impact. The celebration was all the behind-the-scenes stuff coming out."

As a 22-year-old, pot-stirring star of the Flames, Fleury was the prime target of the Oilers throughout a series he said was the filthiest he’d ever been part of.
