Sophomore year of college I didn't shave or trim my beard starting November 1st (No Shave November) to March 1st (Moustache March). The beard was hilarious, I looked like I was from ancient Greece or something, but it's really, really, really hard to meet girls, or even make friends with guys, when you look like the Unibomber.
I say you abstain from shaving/trimming your beard until the sharks win the cup, however long that takes. Either that or start over for the playoffs.
If the Sharks don't make the playoffs, I'll blame your beard.
If the Sharks make the playoffs but are eliminated before winning the Stanley Cup and you (a) did start over at the start of the playoffs, I'll blame the fact that you shaved your beard. But (b) if you did start over for the playoffs I will blame their lack of a cup on the fact that you shaved.
If the Sharks win the Stanley Cup this season you will be required to repeat the same exact process you went through this season from here on out until it doesn't work.
