Since there's an anime thread, I've decided to branch out: what other cartoons do you like?

I'll start.
Adventure Time - It's been getting shaky lately, but ever since the second season, I've been in love with this series. The characters, slowly-growing metaplot, and humor are worth sticking around for.
Gravity Falls - I've seen unfortunately little of this, but what I've seen, I've liked. It's a Disney show that has been legitimately horrifying on purpose, unlike the Disney Channel shows, which manage to be legitimately horrifying by virtue of existence.
Dan Vs. - He's 1/16th Canadian. This gives him the power to turn into a bear. This is the least bizarre and awesome thing about the show.
Bee and Puppy Cat - Not on TV, but it totally should be. The adventures of a socially awkward woman working as a galactic temp agent, and her adorable alien monstrosity.
