Yohan Cabaye's penalty at Reading on Friday night with 10 minutes to go was a big moment in Palace's season.
Score it and the Eagles are going to Wembley for the first time in 21 years, and somewhat making up for a terrible league run in 2016.
Miss it and...well, that horrible run gets a little bit horribler.
But the Frenchman, who has never missed a spot kick for Palace, converted (via a hand from Ali Al-Habsi)
The away end erupted with 5,000 Eagles fans going crazy.
A few fan cams have emerged online of that moment and they're all fantastic to watch. Check them out below.
