The 90s saw a huge shift in children's cartoons. Where the 80s saw over-the-top, morally upright heroes like G.I. Joe, He-Man and the Voltron, the 90s saw a deluge of shows focused on normal, everyday kids like Doug, Recess, and my personal favorite: Hey Arnold!
As a kid, I picked up on a few of the life lessons this show sought to teach kids, but as I've gone back to watch the show as an adult I've begun to understand just how often the Nickelodeon show tackled real-world issues. Of course a short list of GIFs would never be able to capture the nuance and subtlety of this incredible cartoon, but this little piece serves as a sampler of the life lessons this show taught us.
