Jak se zbavit Helenky (1968)

Radio announcer Petrícek (Václav Voska) reads the evening news in a studio. Viki (Jirina Jirásková), the female editor of a woman's program, is annoyed by the stereotypical information he provides as well as by the speaker's melodious voice and his heart-felt performance. Then she gets an idea for a prank. She calls the speaker from the neighboring room on the phone and pretends to be an unhappily married woman who draws all her strength to live from Petrícek's voice.
