So, you ever see some cartoons said to be intended for kids, but you realize that they could ALMOST be seen as more for teens and adults, like say almost to the level of The Simpsons (though to be fair, how many kids WEREN'T watching The Simpsons, lol)?
Here's what I think qualify:
Rocko's Modern Life - One of Nickelodeon's raunchier shows on their kids blocks.
Invader Zim - Same as above
Grim Adventures of Billy and Mandy
Total Drama series
Regular Show - It was even TV-PG, yet still dodged Adult Swim. lol
Animaniacs - Seriously, just look up any montage and it is filled with adult jokes the show provided. Amazing how much the 90's could get away with it.
Ren and Stimpy - Even had an "adult" version on Spike that was so bad, Billy West refused to return for it.
What can you think of, and if you can, why?
