On the occasion of the opening of the famous Vienna "Riesenrad," a competition was held for the best operetta. A Czech, Jára Cimrman, also submitted his entry, a sweeping seven-hour work entitled "Proso." Due to what was perhaps his only negative trait, a slight stinginess, he did not send the score by registered mail, which allowed Franz Lehár, Johann Strauss, Oskar Nedbal, and other members of the jury to literally tear apart the brilliant operetta fresco. After many decades, a team of Czech Cimrmanologists has proven that the author of the world-famous melodies from Die Fledermaus, Polská krev, and many other operettas is the forgotten Pojizeřan Cimrman.
