In the first episode of Charlie Brooker's hard-hitting dystopian Channel 4 comedy-drama, a fictional UK Prime Minister is forced to have sex with a pig after Britain's princess is kidnapped and held hostage by a political artist - an arguably bizarre concept.
But it turns out Black Mirror may not have been so far from the truth, according to the Daily Mail's serialisation of Lord Ashcroft's forthcoming book Call Me Dave, which heralds David Cameron as a pot-smoking, pig-fucking lunatic.
The unofficial biography, co-written by the journalist Isabel Oakeshott, explains how the PM wasn't forced into bed with a pig out of political necessity - like Black Mirror - but rather adhered to an offbeat ritual as part of a university initiation game.
As extracts from the book reveal, Cameron was involved in the notorious Oxford dining society, the Piers Gaveston, which reportedly specialises in "bizarre rituals and sexual excess."
Allegations from the billionaire Tory donor include an "extraordinary suggestion" that "the future PM inserted a private part of his anatomy into" the mouth of a "dead pig" during an outrageous initiation ceremony at university.
Needless to say, the news has sparked outrage on social media, with Twitter exploding with a plethora of tweets offering up comical renditions of Cameron as a pig alongside jokes darker than the Black Mirror series itself. Enjoy:

Crisis on Twitter as photoshoppers can't actually come up with anything more horrific than the reality. #Hameron— James Martin (@Pundamentalism) September 20, 2015
Typical! David Cameron once again hogging the headlines at the Lib Dem Conference.— Paddy Ashdown (@paddyashdown) September 21, 2015
Best question at lobby came from Daily Mail. "Does the Prime Minister still think he had a normal university experience ?"— Patrick Wintour (@patrickwintour) September 21, 2015

The really amusing thing is that just about nobody who's heard this story thinks "I don't believe he'd ever do that". #Hameron— Louis Barfe (@LFBarfe) September 21, 2015
