The phrase Der Hauptmann von Köpenick comes from a celebrated German story about Wilhelm Voigt, who in 1906 dressed as a Prussian officer, took command of soldiers in Köpenick and had the town hall occupied. Carl Zuckmayer later turned the episode into a famous stage play, and it became a lasting symbol of blind obedience to a uniform. Online, the short title is now reused as a compact audio tag for impostor jokes, costume reveals and mock-authority edits, keeping the historical joke recognisable even for viewers who have never seen the play or film.
