The Carolina Hurricanes dipped into their past for a game on Sunday against the Boston Bruins, donning the classic uniforms of the Hartford Whalers.
The Hurricanes franchise was known as the Whalers until 1997.
The reason for the celebration was simple, according to Hurricanes owner Tom Dundon.
The team went all out in celebration of all things Whalers, starting by changing the profile pictures on all social media accounts to the famous whale tail logo.
The uniforms were just as incredible as we all remember.
Goalie Petr Mrazek had a custom mask and pads made for the occasion.
Even Pucky, the Whalers mascot, was in attendance.
And, of course, when a goal was scored, "Brass Bonanza" was played.
And, because it is 2018, emojis were tweeted.
After the 5-3 win, the players, who have found unique ways to celebrate all year, went with what sort of looked like whales out of water in celebration.
All in good fun.
