- Big Name Fan: Maybe not a "fan" per se, but Genndy Tartakovsky cited this as the earliest cartoon he has memories of watching, mainly because it was the only one he could watch in his native Russia.
- Cross-Dressing Voices: Klara Rumyanova as Zayats.
- Fan Nickname: "Soviet Tom and Jerry" is a common nickname for the show for both fans and detractors, even though the creators insist that they had never seen (more specifically, they were unable to see) Tom and Jerry cartoons before creating the show.
- I Am Not Spock: Anatoly Papanov, an extremely talented actor who voiced Wolf, hated being associated with the role.
- Keep Circulating the Tapes: Only the first sixteen episodes (the ones made in the Soviet Union) have been officially released on DVD, and only in formerly Soviet countries, although the entire series (bar the 2012 Christmas episode) has been uploaded to Soyuzmultfilm's YouTube channel. A few appearances by the characters outside of the shorts, such as interstitials for an anthology show of Russian animation, TV commercials and PSAs about energy conservation, are occasionally found floating around YouTube in some capacity.
- Milestone Celebration: Episode 17 was the 25th anniversary special. Wolf and Hare come out onstage in old-age makeup and canes before changing back to their old selves.
- Real-Life Relative: In the Cuban Spanish dub, Hare and Wolf's voice actors (Malena Negrin and Manolo de la Rosa respectively) are married in Real Life, making the whole premise of the show incredibly hilarious by itself.
- What Could Have Been: Wolf was originally supposed to be voiced by actor and singer Vladimir Vysotsky. But the artistic council did not approve the candidacy, and the role was went to Anatoly Papanov. One of Vysotsky's more famous songs, "Pesnya o Drugye" ("The Song About A Friend"), does appear in one of the first episodes, presumably as a holdover.
