Adventure Time is hilarious! What is wrong with you people?! You have to watch it from the first season to get it. There's a lot of silly humor in it, with some adult humor sprinkled in there. It's about a boy and his best friend who's a dog, and they go on daily adventures saving people and having a good time. They live in this other world with multiple kingdoms, so there are a ton of other princesses and princes and kings, etd. that they interact with. If you watch it, you'll get it. They say some off the wall things sometimes. That show is not for kids, but they play it off well. I was cracking up the first time I saw it. Watch the episode with the bears called "Belly of the Beast".
Or watch the one where Marceline gets all deep into her childhood..."It Came from the Nightosphere" I think. Homegirl is really singing a song talking about "Daddy...why did you eat my fries? You stole them, and they were mine." LOL She's all sad and reflective, and she's dead ass serious. It really hurt her feelings and she hadn't talked to him since. And make it so bad, she really sounds good!
The Looney Tunes Show is also updated for adults. They have a ton of real life scenarios that adults would relate to. So it's Looney Tunes all grown up.
Lola Bunny is hilarious because she'not quite dumb as a brick, but not smart either. And she's border-line psycho, because she's stalking Bugs at a certain point.
Bugs is living off the fat of his TV career residuals and royalties, so he doesn't have to work.
And Daffy (who is unemployed) is living with him and mooching. Daffy is the main attraction because he clearly freeloads and takes advantage of everyone else around him, and does not give a f*ck. He'll take something from you, tell you why, justify it, still be wrong, and get away with it until it blows up in his face.
Porky Pig is the pushover friend, but whoops ass after it goes too far.

And the songs that they play in the middle of the episode...

Y'all need to watch it, seriously!
I miss Fosters, too! "I like chocolate milk." <----Most memorable Foster's line ever!
