Strictly Come Dancing Christmas Special
From Tardis Wiki, the free Doctor Who reference
The television show, Strictly Come Dancing, had a yearly Christmas Special. Clara Oswald and her family watched it every year. (TV: The Time of the Doctor)
Behind the scenes
In the real world, the Strictly Christmas special typically airs during the evening (the 2013 special, for instance, aired at 5:00pm). Despite this, it is clearly still broad daylight outside when the show begins playing on Clara's television.
