The Worker & Parasite Show (in Russian Рабочий И Паразит) was a cartoon. When 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," was a cheap replacement; Krusty clearly had not watched the cartoon beforehand to make sure it was a suitable replacement. According to the title screen, it was made in 1959.
