Animaniacs. There’s a lot of adult humor hidden in that show.
Spongebob
Looney tunes and Scooby do, where are you?
All of them. Animation is for everyone, and your never too old to watch cartoons. This is such a bad mindset that we’ve been taught, and it’s really fucked over animation.
Foster’s Home for Imaginary Friends
My real answer is all of them, but I’ll say Foster’s because it has this sweet, and often sanguine quality about it. I honestly was just slightly older than the original target demographic, but I loved that show so much. I feel the same way about Adventure Time as well.
