Halliburton Company is an American multinational corporation and one of the world's largest oil field service companies. It is especially notable for its close ties to former vice president Dick Cheney and numerous controversies.[1]
In "The Legend of Old Ulysses", despite Stan's feelings that Halliburton is responsible for all the good going on, including sponsoring the camp at Possum Lake, several birds, alleging to have once been human, try to warn Steve about the company. One in particular is taken out by a sniper shot through the cabin window while in the middle of trying to tell that Halliburton is trying to turn everyone in the camp into birds.
