We should make it that you can grow whatever facial hair you like, as long as it's a mo for the last day of the month.
Some people feel confident enough with a beard or goatee, but find a mo embarrassing. They might be willing to go through with it on the last day (having just the mo), but not the whole month.
So, in the interests of participation, lets allow any facial hair until the last day. You need to have a picture of that particular days paper (or some other date verification) in the shot with you.
Last day for shaving is 31st of October!
It's gonna be a mo-down.
