It's easy to tell a fellow Whovian that you like "The Ark": they think you're talking about "The Ark in Space." They nod, say "me too" and go on their way. But occasionally, one of them stops, as if to ask, "Did I hear you right?", and warily doubles back: "Not the one with the Monoids?" And you gulp, "Um, yah," and they add, shaking their heads as if they're questioning your sanity, "The ones with the ping-pong balls in their mouths?"
And then you realize you have to provide a coherent, reasoned justification for liking a TV serial that features creatures holding ping-pong balls in their mouths.
