We cannot 100% declare ourselves as complete Linux users or enthusiasts without having boarded the same train with the famed official Linux Mascot, Tux Penguin. There is more to why Linux chose Tux Penguin as its brand ambassador other than the fact that a Penguin has a big head and can adapt to the survival of inhumanely cold weather.
