Gusztáv, also known as Gustavus, was Hungarian series of animated short cartoons for adults. It was extremely popular in Eastern Europe, where it has achieved cult status. It ran from 1964-1977.

Each episode tells an adventure of the main character, Gustav, related to the gray realities of urban life. Characteristic feature of the show was that episodes were independent: for example, Gustav is sometimes a bachelor, sometimes has large family. In Eastern Europe and Yugoslavia the episodes were broadcast on TV in the 80s, usually as airtime filler. The series was also broadcast in Western Europe and even in New Zealand - because it was not using language, other than gibberish sound, it was able to easily transcend boundaries.
