The Ren & Stimpy Show (1991)

S3E8 Stimpy's Cartoon Show

Stimpy is busy creating a cartoon when Ren shows up, claiming that cartoons aren't beneficial for the mind. Realizing that Ren struggles with drawing, Stimpy decides to make him the producer of the project. Ren seizes control over the credits, leaving Stimpy to tirelessly labor on the cartoon. Once it's completed, they get the chance to present their work to Wilbur Cobb, the esteemed "godfather of animation."
