Upon the advice of rustydog, I am posting a Doctor Who quote:
DOCTOR: "Suppose he wants to broadcast some pleasing bit of news, like the imposition of a double vision tax on people with more than one eye. Well, then he feeds it into here."
LEELA: "No, he fed it into here."
That's from "The Sunmakers," a Fourth Doctor adventure. The idea of a double vision tax never fails to tickle me, and I like the way that Leela punctures The Doctor's attempt to show off his supposedly intuitive understanding of technology.
