I Am Weasel is an American animated television series produced by Hanna-Barbera with Cartoon Network Studios, created by David Feiss, and broadcast on Cartoon Network.

The series chronicles the adventures of I.M. Weasel, an internationally famous, rather eloquent, highly intelligent and much talented weasel who is adored by everyone, and I.R. Baboon, an ugly and idiotic baboon who is envious about Weasel’s success and constantly tries to be better than him. The show premise begins from a humorous take on the classic nursery rhyme “Pop Goes the Weasel”; in fact, the series theme song, composed by Bill Fulton, written by Richard Pursel, and sung by April March, is based on the well-known musical version of the rhyme.

I Am Weasel was originally a part of the Cow and Chicken show, often airing as the third of three segments in an episode, after two Cow and Chicken segments. Eventually, I Am Weasel was spun off into its own series, aired in 1999 with reruns airing until April 2006, with both new episodes and the episodes that had aired on Cow and Chicken included in this series, totaling 79 episodes.

Today, the series is labeled a classic of Cartoon Network’s late 1990s collection of Cartoon Cartoons. Since April 13, 2012, it is being aired on Cartoon Network, on the block Cartoon Planet. This show also airs on Boomerang, but only airs seasons 1-4 with the Cow and Chicken segments.

Cow and Chicken is an American animated comedy television series created by David Feiss for Cartoon Network. The series follows the surreal adventures of a cow, named Cow, and her chicken brother, named Chicken. They are often antagonized by “The Red Guy”, who poses as various characters to scam them. Late into the series run, the characters I.M. Weasel and I.R. Baboon, who were part of the series’ recurring segment, I Am Weasel, were given their own half-hour series of the same name.

Like Dexter’s Laboratory and some other Cartoon Network series from the 1990s, the original pilot appeared as an episode of the animated shorts showcase project What a Cartoon!, the brainchild of Fred Seibert, then-president of Hanna-Barbera. The Cow and Chicken series first broadcast on Cartoon Network from July 15, 1997, to July 24, 1999, with reruns airing prominently on the network until April 2006. Reruns are played on Boomerang, which are rated TV-Y7. The series was nominated for an Emmy Award in 1996 and 1998.

As of March 30, 2012, this series has returned to Cartoon Network in re-runs on the revived block, Cartoon Planet.
