Zhenya spends the entire flight sleeping on the shoulder of his annoyed seatmate, played by the director himself (Ryazanov) in a brief comedic cameo appearance. The seatmate helps Zhenya get off the plane in Leningrad. Zhenya wakes up in the Leningrad airport, believing he is still in Moscow. He stumbles into a taxi and, still quite drunk, gives the driver his address. It turns out that in Leningrad there is a street with the same name (3rd Builders' street), with a building at his address which looks exactly like Zhenya's. The key fits in the door of the apartment with the same number (as alluded to in the introductory narration, "...building standard apartments with standard locks"). Inside, even the furniture is nearly identical to that of Zhenya's apartment. Zhenya is too drunk to notice any minor differences, and goes to sleep.
