The first Doctor Who story to be broadcast on Christmas Day was way back in 1965. The Feast of Steven ended with the Doctor raising a toast and wishing the viewers at home a happy Christmas. It's a bit rich given that Christmas with the Doctor always go pear-shaped.
There are two certainties in life. Number one - whenever the Doctor is around you can bet that we’re all in big trouble (or as Clive put it to Rose “if the Doctor’s making house calls then … God help you”), and number two - Christmas Day will be one of his busiest, with all manner of aliens choosing to pitch up to spoil the party.
When it comes to Christmas, nothing is sacred and everything is fair game to alien invaders and even the Doctor himself. From something as innocuous as a child’s toy to the heavenly host of angels, not everything is quite what it seems.
Instead of offering platitudes, the Doctor should be issuing every household with a Christmas Survival Guide, just in case he’s otherwise engaged with a twenty-four year passion-fest with River Song on Darillium, or getting sloshed on Gallifreyan sherry with his latest companions in the TARDIS.
In the event that the said book fails to materialise inside your Christmas stocking, here are a few handy hints.
