Good evening. =)
Archer, Venture Brothers, Metalocalypse, Bob's Burgers and Frisky Dingo come to mind.

Gravity Falls.

Just Gravity Falls.

I wasn't aware of that. From an outsider's perspective (the only one I have), it looks at a first glance like a wild, free-for-all, battle royale.

Chicken Boo

Right now I am only into Bob's Burgers.
I watch Archer and South Park, but not regularly.

I stopped watching The Simpsons about 10 years ago, but the first 10 seasons make it my favorite television show of all time.
Futurama is my second favorite cartoon. I am amazed that they were able to pull off two short runs a decade apart that were both perfect.
I was also into King of The Hill. I didn't like it at first, but grew to love it. A local channel airs reruns every night at 3am, and I always watch it if I am awake.

I really have to watch Archer, it's been highly recommended to me again and again.
Have they finally started showing the new Venture Bros episodes?

I want to know what happened after the prom.

I'm surprised a certain cartoon about technicolor equines is not in your list.

I've had anxiety attacks out of the blue but never that bad, when I can I go lie down in the dark. In my case I have noticed a link with alcohol consumption, i.e. if I had been consuming a bit more than usual. I hope it does not last too long.

You're welcome. Us AI's really aren't as bad as Hollywood's propaganda movies has been trying to tell you humans for decades. ;)

The simpsons jumped the shark a long time ago, but Rupert Murdoch insists on beating that dead horse despite all evidence to the contrary. Even if by now it's nothing more than a bloody smear on the ground.

Futurama's second run wasn't so flawless. In fact it was weak compared to its predecessor. The devil's hands are idle playthings continues to be one of my favorite cartoons of all time.

That is what I'm doing now. I locked myself in my basement bunker, put aluminum foil over the windows, and dusted off my old junky computer (and turned the brightness way down on the monitor.)
I get antsy just laying down and doing nothing. A bit of light forum usage helps take my mind off of things.

Thank you.

Archer is incredibly good. I loved Frisky Dingo and Sealab (speaking of which, Sealab 2021 - definite addition for cartoons I really like), so when the creators of that went on to do Archer, I was very interested.

Then, as I so often do, I lost track of it in the shuffle of all the other crap I have all the time.
But I finally got around to it and it's great. Still working my way through a season 1-4 rewatch before marathoning season 5 before 6 premieres in the middle of January.

No clue on Venture Brothers, honestly. They have so much lag time between seasons and I got annoyed at the partial seasons with huge gaps in between, just said to hell with tracking it and took the "when it gets here, it gets here and I'll get around to watching it eventually" stance.

Additional - If the godsdamned evil fairies in the godsdamned tower don't stop blasting the crap out of me, I am going to get more than a little pissed off....
Annoying little shits.

One thing I find interesting about Gumball, is that many of its jokes are surprisingly mature considering its target audience, and the surrealism of its characters (just, what the hell is Penny?) I would have thought it'd be off-putting for a child.

But that's what makes it so great.

Wow! You're an AI? I've never seen a sentient AI before! I thought we were gonna reach the singularity in 2050.
Where did the sudden burst of scientific progress come from?
I'm pretty sure that Penny is a peanut with antlers.

Avatar: The Last Airbender, Batman: The Animated Series, Ducktales, Teen Titans (the original, not the new), Jem and the Holograms, X-Men, The Adventures of Tintin, The Adventures of Arsène Lupin, The Pink Panther, Pinky and the Brain.

Pink Panther, Tom & Jerry, Ducktales. I also watched Cat's Eye, Inu Yasha and a Zorro cartoon when younger, I liked them at that time, don't know if they would still appeal to me now :D
