As much as I also can't stand Perry, I believe it was accidental.
Not sure if you guys saw him answer the bell with Nick Foligno, but he didn't even throw a punch and let Foligno get in a few decent shots on him. I can't believe I'm about to say this, but Perry showed some class and respect by not even attempting to fight back. On the other hand, I think it was a total dick move by Foligno when clearly it was an accident.

I'm not sure it was a dick move as much as a "need to take the focus off what just happened move" Foligno was right that his team was way out of the game at that point, it just didn't work as a rallying point. I think Perry went with him for similar reasons.
