This is hilarious, cute, worrisome, and depressing all at once.
Hilarious: Great way around the rule. How can you stop it? They are being gentlemanly about it and playing/fighting within the rules (as ridiculous as they are).
Cute: How awkward they are. It's like two teenagers figuring out where to put their hands for their first dance. They are both obviously aware of their roles and both trying to stay on the big team. They both don't want to hurt each other (by letting the other remove the helmet) but immediately start to try to hurt each other. This is both cute and honorable and one of the reasons I love hockey fights, the pageantry of two enforcers knowing they have to meet at some point and being classy about it. Some people hate the "set up" fights, but I think that the fans of each of the teams want to see it and are somewhat disappointed if they don't. The other reason being the pure hatred that is built up over a game/season/career that is only curable through fists. Those fights are usually better (Mac/Lemieux).
Worrisome: This isn't going to last long. I bet the first draft of the rule is already written. Probably 2 for delay of game, 5 for fighting, game-misconduct, and maybe a short suspension/small fine.
Depressing: That it's come to this. So many recent, stupid rules (instigator, jersey tuck, glove tuck, goalie pads, puck over glass, trapezoid, spin-o-rama, stick curve, GOALIE INTERFERENCE OR NOT!?!?, and the dumbest: OTL). It's killed the game and made it so complicated that causal and new watchers are so confused that they won't attempt to watch it. If I were to talk to one of my co-workers who I know are into sports (NFL, NBA, MLB) and ask them what they know about hockey, 90% would mention "allowed to fight" in their answer. If I ask them why they don't watch it at least half would say "confusing/rules are weird."
I predict this will ultimately result in the creation of an entirely new sort of pest/agitator: the tucker. His sole purpose: to tuck the opposition's jerseys, twice. Or several times. Or dozens of times.
