a short doctor who episode by steven moffat
It’s 1770. Frederick the Great looks into the distance and says “I’m going to invade Russia.” Then he thinks. “No, I’ll just work on industry instead.” At that moment, the clouds part, and Charles XII descends in a ray of sun. He smiles and places a hand on Frederick’s shoulder. “You did it,” he says, “You passed history.” It’s over. Prussia lives to see another day.
It’s 1812. Napoleon Bonaparte looks into the distance and says, “I’m going to to invade Russia.” Meanwhile he thinks, “what can go wrong, I’m me after all.” Suddenly the heavens open and Frederick the Great descends from the clouds in a fiery golden chariot of light. He looks sternly at the Emperor before saying, “do it for the vine.” Prussia will have its revenge.
