Hi Everyone! Most of tu may know that Stan's birthday is on October 19. However, everyone (Except Maybe Trey and Matt) most likely doesn't know is birth year. Of course this is not official, but this is based of research I've done on the franchise itself. So if tu have any opinions please feel free to argue. I will listen.
As of "You have 0 Friends" it shows at about 10:28 that Stan was born in October 19 2001. As much as this may seem like it sounds accurate, I say it isn't enough.
