Call Of Duty Black Ops Easter Egg - Treyarch's Own Drink

After you start the Campaign of Black Ops, you will have the long cut scene of the guy being tortured at the beginning about Operation 40; after all of that there is the part where you are planning the operation in the bar. After the part where you attack the soldiers inside, look around some of the tables in the bar (and some outside, on the right of the bar as well), there will be some white-and-orange cans on them, and if you look carefully at the cans, the name on them is the creator's name, "Treyarch."
