With two seconds remaining in the first period of Game 3 between the Pittsburgh Penguins and Ottawa Senators, Ottawa's Marc Methot took a tripping penalty when he tangled up Evgeni Malkin and sent the Pittsburgh star crashing into the net on a scoring chance.
The net camera caught Malkin's reaction up close, and it was glorious:
Malkin was mad, and he let the officials know it after he managed to climb out of the net. The Penguins felt that Methot's last-second takedown should have been a penalty shot, and captain Sidney Crosby spent several minutes after the final whistle discussing it with the officials, but it was just a regular old tripping penalty instead.
The Penguins failed to score on their power play at the start of the second period, even though it involved a brief 5-on-3 opportunity. If you want to know how Malkin feels about that, just watch the above GIF a few more times.
