Changelings are marching on Canterlot. In a last ditch effort to save themselves, the Princesses attempt to summon the great hero and saviour known only as 'The Doctor' to Equestria.

He's much more vulgar than they anticipated...and very affirmative that he is not in fact a doctor, or hero, or generally a nice person.

Expect lots of swearing! Contains improbable sexual humor and potentially offensive humor.
Crossover with The Thick of it, along with plenty of Doctor Who references.
