Taking something and turning it into a representation of Adolf Hitler, whose father's original name was Alois Schicklgruber.
See Wikipedia for biography: Alois Hitler was born
illegitimate. For the first 39 years of his life he bore his mother's surname, Schicklgruber. In 1876, he took the surname of his stepfather, Johann Georg Hiedler. The name was spelled Hiedler, Huetler, Huettler and Hitler and probably changed to "Hitler" by a clerk. The origin of the name is either from the German word Hittler and similar, "one who lives in a hut", "shepherd", or from the Slavic word Hidlar and Hidlarcek.
Allied
propaganda exploited Hitler's original family name during
World War II. Pamphlets bearing the phrase "Heil Schicklgruber" were airdropped over German cities.
