Get the Mustaches mug.
A universal icon representing the epitome of authority and raw **manhood. It graces small children the chance to believe in a hero and causes evil-doers to second guess their existence. There are very few things in this world that could ever achieve the divine status that each individual hair is birthed into. Resting just above the upper lip, the mustache is a beacon to all mankind that there is hope for this world and a bright future for all who have been gifted with this treasure from God himself.

** I used manhood as a majority observation. No disrespect to the women of this world that wear their mustache with pride.
When I grow up I want a mustache like that.
