In 1999, Cartoon Network premiered its sixth Cartoon Cartoon series, titled "I Am Weasel". Unlike any of the original series before it, I Am Weasel was a spin-off of David Feiss's original series, Cow and Chicken.  In fact, the first season of the show consisted of "Weasel" cartoons pulled from Cow and Chicken. Once again David Feiss created an animated program about two talking animals thrown into some rather obscure situations.

     I Am Weasel is the set of adventures of the title character, a highly intelligent mammal, and his constant, albeit stupid rival/partner, I. R. Baboon. The two are often competing in different humorous situations, with ‘I. R.’ trying to out-do Weasel at every turn. However, I. M. Weasel, the world renowned professional of everything, always seems to come out on top. Look for The Red Guy (from Cow and Chicken fame) to appear in each episode, usually instigating trouble between the two.

     Officially, the series started in 1999, but the first season of episodes were in fact pulled from the Cow and Chicken series produced back in  1997. A second season of all original cartoons was produced and aired the following year. I Am Weasel wrapped up in 2000 after three seasons.
