'I Am Weasel.' is an American animated television series, created by David Feiss and broadcast on the Cartoon Network. Its basic premise is a somewhat twisted take on the classic nursery rhyme "Pop Goes the Weasel"; in fact, the theme song of the series, 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 middle of three segments, in between two Cow and Chicken segments. ("The Ugliest Weenie", a two-part Cow and Chicken story, even made reference to the I Am Weasel cartoon interrupting the storyline.) Eventually, I Am Weasel was spin-off into its own series, airing between 1997 and 2001, with both new episodes and the episodes that had aired on Cow and Chicken included in the series (much like how Pinky and the Brain was spun off from Animaniacs or how Evil Con Carne came from Grim and Evil).
