Alex Ovechkin sent the Verizon Center into a frenzy after he scored his 500th career goal in the NHL.
Here are some videos of the unforgettable moment from those fans who were lucky enough to see the milestone in person.
A game that started off with so much hope and promise finished with a sickeningly familiar feeling as the Capitals squandered a 2-0 lead in a 3-2 Game 1 loss to the Pittsburgh Penguins.
Evgeny Kuznetsov scored just 17 seconds in and Alex Ovechkin put the Caps up 2-0 at the start of the third, but three the Penguins responded with three third-period goals to stun the Caps.
Here are the three stars of the game.
3 Stars of Capital vs. Penguins Game 1:
1. Jake Guentzel: Guentzel had 22 goals and 48 points in the regular season. Not a bad season by any means, but nothing to suggest he would turn into the second coming of Mario Lemieux in the playoffs again. Geuntzel clearly elevates his game when it comes to the playoffs and boy did he come up big for Pittsburgh. Down 2-0 in the third, Guentzel assisted on Patrik Hornqvist's goal. Less than three minutes later, Guentzel at the blue line found Sidney Crosby with a cross-ice pass that Crosby was able to easily score on. Then Crosby returned the favor with a shot that Guentzel was able to deflect in for what would be the game-winning goal.
2. Alex Ovechkin: Once again, Ovechkin delivered in a big playoff game and once again, it wasn't enough. Ovechkin floated a pass to Kuznetsov behind the defense that Kuznetsov netted for a goal 17 seconds into the game. At the start of the third period, Ovechkin took a 2-on-1 opportunity and sniped the top corner to put the Caps up 2-0.
Say what you want about how one-sided the Ovechkin-Crosby rivalry is, but you could not come away from this game saying the Caps lost because Ovechkin doesn't perform in big moments. His performance indicated otherwise.
3. Matt Murray: Giving up a goal 17 seconds in is not an auspicious start, but Murray certainly recovered well.
Murray made 32 saves, several of which were of the phenomenal variety. The save of the game came in the second period when Murray extended the arm to deny Devante Smith-Pelly on what looked like an empty-net rebound opportunity. The puck bounced off the glove of Murray’s blocker. Once the Penguins took the 3-2 lead, Murray was absolutely lights out.
So maybe this is the Capitals' year after all.
At roughly 7:10 p.m. ET on Thursday night, the puck was dropped on the ice to signify the start of Game 1 between the Penguins and Capitals at Capital One Arena.
At roughly 7:11 p.m. ET, Evgeny Kuznetsov was celebrating his first goal of the series.
That's right, Kuznetsov scored on the very first shot attempt of the series, beating Penguins' goaltender Matt Murray at 0:17 of the first period.
Alex Ovechkin and Tom Wilson assisted on the goal.

Seventeen seconds is mighty fast, but it won't even get Kuznetsov on the Top 10 list for fastest playoff goals.
Don Kozak holds the NHL record, scoring on a breakaway just six seconds into Game 4 of the 1977 quarterfinals between the Los Angeles Kings and Boston Bruins.
Just last season, Blue Jackets' Cam Atkinson scored 11 seconds into Game 3 of Columbus' first-round series against the Penguins' goalie Marc-Andre Fleury. Atkinson sits at the No. 10 spot.
The Capitals' record for fastest playoff goal is 15 seconds, scored by Mike Gartner in Game 1 of the Capitals 1987 NHL Playoff series against the New York Islanders.
Kuznetsov will have to settle for giving the Caps the best type of start to the series.
