I think this is what the NFL had in mind...
...when they originally created the rule against excessive celebrations. Of course, now they throw a flag if a player so much as cracks a smile or lifts his arms above his shoulders after a score. The mirthless old farts.
Still, this little celebration is excessive.
The most amusing part of the video is the close up of the score at the end. It explains why there's no footage of the other guy beating the celebratory dancing moron into a ping-pong-pulp with his racket.
Of course, maybe he also danced after every point. There's no way to know for sure.
