Die Feuerzangenbowle (The Fire Tongs Bowl, The Punch Bowl) is a German book, later adapted into several films, which tells the story of a famous writer going undercover as a pupil at a small town gymnasium after his friends tell him that he missed out on the best part of growing up by being educated at home. The story in the book takes place during the Weimar Republic in Germany. The novel by Heinrich Spoerl was published in 1933 and was adapted to film three times. The 1944 movie of the same name directed by Helmut Weiss is the most notable adaptation of the material. This German comedy classic was one of the last big movie productions in Germany before the end of the Nazi era and has gained cult status at German universities since the 1980s.
The movie’s release was in question when Bernhard Rust, secretary of education and former high school teacher, bristled at the way the movie poked fun at teachers. To circumvent a ban by the censorship board, producer Heinz Rühmann presented the movie to Hermann Göring at the Führerhauptquartier where it proved to be a success, thus affecting its delayed release on February 28 of 1944 in Berlin.
