From a Wired article on geekiness in Futurama:
Cohen refers to a One Percent Rule that guided the writing on Futurama. When they were scripting the episode "Kif Gets Knocked Up a Notch," a character claims that he painstakingly programmed a holographic simulation using "4 million lines of BASIC." One writer pointed out that 99 percent of the audience wouldn't get the reference to an old programming language. Producer-writer Eric Kaplan responded, "Fuck them!"
