Here at HuffPost UK Comedy, we don't endorse getting bladdered over Christmas - or at any time of the year - of course. Ahem.

As zeezromnomnom explained: "My wife put a Santa hat on the corner of our TV. I thought it was simply a festive decoration until I started watching The West Wing"...
Wonderful stuff. We're sure this is going to make all those BBC repeats much more bearable over the festive season...
