To celebrate the opening of Vienna's iconic Riesenrad, a competition was announced for the best operetta. A Czech man named Jára Cimrman submitted his ambitious, seven-hour work, "Proso." Because of his characteristic stinginess, he didn't send the score by registered mail, which allowed the jury—including Franz Lehár, Johann Strauss, and Oskar Nedbal—to thoroughly critique his masterpiece. Decades later, a team of Czech scholars has definitively proven that Cimrman was the creator of the famous melodies from operettas like "Die Fledermaus" and "Polská krev," and many others.
