Worker and Parasite was a "fictional" cartoon on the animated television show The Simpsons. In the episode Krusty Gets Kancelled, the popular cartoon Itchy and Scratchy, featuring a very violent cat and mouse, leaves the Krusty the Clown Show for Krusty's new competitor, Gabbo. "Eastern Europe's favorite cat and mouse team, Worker and Parasite" were a cheap replacement. According to the title screen, it was made in 1959 under the Khrushchev regime in the USSR.

The cartoon opened with some cyrillic-looking credits. The cartoon itself was quite unintelligible, and featured a crudely drawn cat and mouse chattering incoherently and bouncing around in front of a breadline of identical, miserable-looking peasants, while random background-music was playing. The whole thing ended with the screen reading "Endut! Hoch Hech!" Krusty's on-air response afterwards was shocked silence, a limp cigarette and then: "What the hell was that?!"

The episode can be seen here.

Coincidentally, the idea bears some similarity to the rather unusual set of Tom and Jerry cartoons (on which Itchy and Scratchy is based) produced in Prague by animator Gene Deitch.
