The fourth of the four plots of the animated almanac Merry Go Round No. 1.
The animated film is a prototype (more precisely, a pilot release) of the main animated series "Well, wait a minute!", which appeared later that year.
It was in this mini-film that the scriptwriters - Feliks Kamov, Aleksandr Kurlyandskiy, and Arkadiy Khayt set the rules by which they were "played" in all future episodes.
