I Am Weasel was one of the first few cartoon cartoons on Cartoon Network. The show, created by David Feiss, is quite good.
The animation in the show isn't really great at that time as they did indeed use crude humor. The characters, Weasel and I.R. have very easy-to-know personalitys. The episodes with them are quite good as we also see I.R. Babboon win sometimes. ANd, the Red Guy is supposedly alot of viewer's favourite characters for the funny roles that he plays in the show. And cameos of Cow and Chicken make the show even better than most people think.
Overall, I think I am Weasel is a superb show and if you are a Cow and Chicken fan, I do recommend you to see this series.
