The first version of the drama included a quote that gained fame fast. In the third act, Götz is under siege by the Imperial Army in his castle at Jagsthausen. The captain of the army asked him to surrender; from a window, he gives his answer:
Mich ergeben! Auf Gnad und Ungnad! Mit wem redet Ihr! Bin ich ein Räuber! Sag deinem Hauptmann: Vor Ihro Kaiserliche Majestät hab ich, wie immer, schuldigen Respekt. Er aber, sag's ihm, er kann mich im Arsch lecken!
— Johann Wolfgang von Goethe, Götz von Berlichingen mit der eisernen Hand, act 3, Goethe's Werke, vol. 8 (1889), p. 109 It can be translated as:
Me, surrender! At mercy! With whom do you speak? Am I a robber! Tell your captain that for His Imperial Majesty, I have, as always, due respect. But he, tell him that, he can lick me in the arse!
Goethe based this passage on the autobiography of the historical Götz, who records himself as saying (in a different context) "er solte mich hinden lecken" ("He can lick me on the behind").[3] (In reality, the besieger was Götz himself.)
And this was all after the fall of the Roman Empire? I find it difficult to believe...

How humanity has managed to get that far without any written record of this splendid insult escapes me.
