Rooster Teeth Productions
From Halopedia, the Halo wiki
Summary
Rooster Teeth Productions is the name of the company which makes Red vs Blue. The name originates from a common insult in Red vs Blue, "cockbite." As such, the company logo consists of a silhoutte of a rooster and a wind up chattering-teeth toy.
Easter Eggs
In one of the Halo 2 multiplayer maps, Turf, you can find two soda machines. One has a picture of a rooster with a blue silhouette on it, the other has teeth with a red and green silhouette. One of them is near the tent and the other is in the "warehouse", the room with the swing doors. This Easter Egg is referenced in an Easter Egg from the season five DVD in which Church shows Doc the logo. Despite Church's many hints to Doc, he never gets it and just thinks that it says "Soda pop".
On the Halo 3 level,Crow's Nest, various voice actors from Red vs. Blue (including Grif) can be heard having an argument. The most humorous is the Easy and Normal difficulty levels in which the marine in the door says that the other marine is a Brute or Brute prisoner and when the other one says he's not, he says he is definitely not opening the door now.
