The truth is, you're not really a true Brit if you haven't spent at least one hour of your life watching an episode of Doctor Who. Whether it was behind the sofa as a kid or behind a cushion as an adult, the cult sci-fi show should definitely be part of a citizenship test, along with sarcasm and complaining about the weather.
Failure to impress us with your Who knowledge may result in instant deportation. Okay so that's a lie. We'll just be really disappointed.
