I learned on an NPR quiz show long ago, that according to some book mullets came into fashion in medieval times so peasants working in the field could keep the elements off their necks while not impairing peripheral vision — so they could spot bandits and raiders. It makes sense, I guess, as far as it goes.
Tonight I was watching clips of hockey games before the helmet was required, and it was a mullet-fest. And you know? It makes sense, for exactly the same reason. It’s cold on the ice, but a hockey player without peripheral vision is going to have a hard time of it. In that environment a mullet is… sensible. There, I said it.

From there, it practically writes itself.
