As alluded to in the post game recap, Jack Johnson got down and one knee, mimicking Tim Tebow's touchdown/post game/whatever celebration. Just a case of a player having a bit of fun after scoring, but it's almost instant youtube fodder.
The goal itself is quite technically sound. Winger Kyle Clifford pulled the play to the right, then found Jack Johnson trailing the play in the center. Johnson shot off his first touch, putting it under a defender's stick and through Vokoun's five hole.
