How a nursery rhyme and a classic novel birthed a cartoon rivalry

In short: Created by David Feiss, I Am Weasel began as a simple doodle inspired by Richard Matheson’s I Am Legend. By pairing a hyper-competent weasel with a dimwitted, envious baboon, Feiss tapped into the classic Pop Goes the Weasel rhyme to craft one of Cartoon Network’s most enduring and successful animated sitcoms.

The series, which ran for 79 episodes, originated as a segment within Cow and Chicken in 1997 before spinning off into its own standalone show in 1999. While the first season presented I.M. Weasel as a flawless, heroic figure, the show’s dynamic shifted significantly over time. As the audience and the world within the show grew increasingly foolish, the once-noble Weasel began to show human-like flaws, while his rival, I.R. Baboon, gradually ascended to a hero status of his own.

This evolution was bolstered by the introduction of the Red Guy, a flamboyant, pants-less devil character who migrated from Cow and Chicken. His presence, starting in the second season, allowed the show to embrace a more chaotic, slapstick style of humor. The production, handled by Hanna-Barbera in Los Angeles with animation work in Seoul, frequently broke the fourth wall, with characters offering advice or commentary directly to the audience.

The show’s legacy is marked by high ratings and a unique place in 1990s animation history. Despite its success, it faced one notable legal hurdle in 1999 when the University of Nebraska sued over the use of a letter on a helmet, leading to digital censorship. By the series finale, the narrative arc was complete: the idiotic baboon had officially usurped the intelligent weasel as the true star, cementing the show's subversion of traditional protagonist tropes.
