The Pythagoreans

Students are meeting up in front of a station. They are going on a school trip to Karlštejn led by Professor Danda. Everyone is dressed casually and has a knapsack. Only Zachar and Zach are in dark suits, bowties, and shiny patent-leather shoes. They even carry black umbrellas. Professor Danda has a sense of humour, calmly accepts their joke and in the same way tries to put up with their "philosophical" speculations and comments. The two students loudly praise a Pythagorean theorem as a superb literature. At Karlštejn, Zach and Zachar accidentally become witnesses at a wedding of a young soldier and his even younger bride. On the riverbank, they create a feast for the penniless newlyweds out of their fellow students' lunchboxes. Only a miserly fat fellow refuses to give up his sandwich, and so the two practical jokers put a worm they picked up from a fishing rod between his hidden slices of bread and butter. The bride's parents spoil the celebration. The wedding is taking place against their will and they are determined to catch the fleeing couple. Finally everyone - the students, the young couple, parents and the professor, end up fully dressed in the river, and swim down the Berounka and then the Vltava all the way to Prague. They pass Vyšehrad, swim under four bridges, and end up in the small Čertovka (Devil's) stream. There, Zach and Zachar praise the school trip and mutual tolerance between the students and the professor. Professor Danda takes out a handle and closes the door on the entire story behind him.
