This segment sets the stage for the slapstick humor that's prevalent throughout the film.

The second part, "Naparnik" or "Rival," delivers a romantic flavor to the film. Natalya Seleznyova stars as Lida, the love interest of our protagonist. This story is an illustration of a charming and humorous love story between Shurik and Lida. Even though they are college students, they show some maturity through their romantic relationship. However, Lida's other suitor complicates things by hatching an elaborate plan to disrupt their budding romance. A dramatic turn of events occurs, significantly impacting both Shurik's personal and academic life.

In the final part of the movie - Operation Y, Shurik is embroiled in a comical heist plot. This part of the film notably features renowned comedy trio Yuri Nikulin, Georgy Vitsin, and Yevgeny Morgunov - playing the mischievous cowards who are planning to rob a warehouse. Shurik finds himself in the middle of their nefarious plan, mistakenly becoming the warehouse's security guard. What follows is a barrage of physical comedy, clever gags, and bumbling altercations.

Throughout the three stories, director Leonid Gaidai paints a comical and delightful picture of Soviet society during the 1960s. Each segment maintains its independent integrity while weaving Shurik's character development across all parts, providing continuity and a steady flow of humor. The director skillfully balances a charming love story, a light-hearted portrayal of student life, the naive innocence of the countryside confronting the cunning of the city, and culminates in an elaborate comic heist plot.
