Rocko's Modern Life is an American animated sitcom created by Joe Murray for Nickelodeon. The series centers on the surreal life of an anthropomorphic Australian-immigrant wallaby named Rocko as well as his friends: the gluttonous steer Heffer, the neurotic turtle Filburt, and Rocko's faithful dog Spunky. It is set in the fictional town of O-Town. Throughout its run, it was laden with adult humor, including double entendre, innuendo, and satirical social commentary, similar to The Ren & Stimpy Show.
Murray created the title character for an unpublished comic book series in the late 1980s, and later reluctantly pitched the series to Nickelodeon, who were looking for edgier cartoonists for their new Nicktoons. The network gave the staff a large amount of creative freedom, with the writers targeting both children and adults. The show premiered on September 18, 1993 and ended on November 24, 1996, totaling four seasons and 52 episodes. A TV special was announced in 2016, and is set to premiere in 2018.
The show is notable for launching the careers of voice actors, including Tom Kenny and Carlos Alazraqui. After the show's cancellation, much of the staff regrouped to work on SpongeBob SquarePants, created by Rocko's creative director Stephen Hillenburg.
