The Doc Holiday can features a rifle and a man on the front (who I can only assume is both Doc Holliday and the owner of the gun) and claims to be loaded with "double barrels of flavor". Doc Holiday can be bought here. So after waiting a month for my shipment to arrive as if I were waiting for a decoder ring, I was terribly disappointed. Instead of the double barrels of flavor that I was hoping for, all I got was a punch in the mouth. Weak flavor and very little kick. Averaging the poor taste with the strong historical deference, Doc Holiday earns a two Dr Pepper can rating. This drink should not be confused with Doc Holiday, which also looks quite tasty.
