7. "To Heck And Back" - Rocko's Modern Life
NickelodeonRocko's Modern Life was known for pushing the envelope in children's television, including a restaurant named Chokey Chicken and Rocko even working as a phone sex operator. It was exactly the kind of cartoon that your parents didn't want you to watch, which made actually watching it all the more fun. In one of the darkest moments of the show, an episode titled "To Heck and Back" saw Rocko's pal Heffer choke to death on a piece of chicken and get sent to their own unique vision of Hell; known as Heck. Even if you happen to be the most mature child on the planet, it's kind of hard to watch Heffer die a painful death and then fart out his own soul as he descends into Heck. His detour is also filled with tons of self-hatred, with Heffer even proclaiming that he's glad to be dead and being forced to watch Rocko die over and over again while trapped inside his monstrous stomach. Though it masqueraded as a kid's cartoon, Rocko's Modern Life would often play jump rope with the genre, and never more so than in this episode.
