Well, whenever there's a new Doctor Who episode on, anyway! If you're planning a weekend trip to the cinema or holding your hopes out for a much needed date night, think again. When the series is airing, Saturday nights are all about the Doctor. The evening will consist of switching the lights off, unplugging the phone and watching the drama unfold. You probably won't be allowed to talk while it's on, either, and that's a lesson you probably wouldn't want to learn the hard way. You probably won't see much of them after the episode, either, as they'll no doubt spend the rest of the night discussing the latest episode's themes and developments on the Doctor Who message boards. At least it means you get a night to yourself. Every cloud.
