It's like that one episode of Daria, where the school needs funding desperately. So, out of desperation (and greed), the principal signed a deal with the cola company, Ultra Cola, which looks like mountain dew. Near the end of the episode, almost everything is Ultra Cola branded, even the curriculum has the branding and slogabs in it. The principal is so desperate for the money, she goes total meltdown from drinking the soda, even chopping the soda machines placed everywhere in the hallways, with a fire axe, and ends up having a mental breakdown.
