Grim Adventures of Billy and Mandy
Crazy cartoon where the Grim Reaper has a Jamaican accent and is subservient to two psycho kids. This cartoon scratches a particular itch no other cartoon does haha, its good stuff
Edit: by kidult, I mean it has appeal to both audiences with stuff that goes over kids heads often and is probably super inappropriate situations/lessons, and such
Edit: I might be also referring generally to content from outlets/studios like
- Nickolodeon
- Teletoon
- Adult Swim
- CartoonNetwork
- some YTV
- Hannah Barbara
The last one that I can think of is probably Gundum Wing, although I watched a lot of Flinstones reruns growing up as well. Almost everything in both of them went way over my head as a kid.
