Apart from being renowned for his iron hand, he was also known for the Swabian salute: "Leck mich am Arsch" (akin to expression "kiss my arse", but literally "lick me on the arse")
> Er aber, sag’s ihm, er kann mich im Arsche lecken
He may lick me on my arse
Which is for a German reader a tad less offensive then "Leck mich am Arsch"
