Tom and Jerry. Because... Uh.... I mean.... It's Tom and Jerry? How much explanation is needed? (assuming you meant animated as in everything considered animated and not anime)
Anything animated. Animated shows, anime, doesn't matter. If it was animated and you liked it, go ahead and post it.
I'm not sure. Either Looney Tunes, or Futurama. They both heavily influenced my childhood, were brilliantly-written, and had me rolling on the floor laughing on a constant basis. TOTALLY DIFFERENT FROM ONE ANOTHER TOO.
The anime, One Piece, is my favorite show of all time. I've watched it since I was a 5th grader. That show had me bawling my eyes out on numerous occasions because of how much character development there was. It really influenced the way I draw things and how much I care about character development as of now. Also, I think the show is hilarious.
I can't choose one. So I'm putting it into a partial list. 1.0 Gravity Falls (Above and beyond amazing. It astonishes me to this day that it's a Disney show considering it is the exact opposite of what a typical Disney show represents. I have never seen such an beautifully woven story--not to mention it has no hand holding. It's extremely dark, especially for the standard cartoon. Not to mention the animation is absolutely gorgeous.) 1.1 Steven universe (Has all of the good qualities of Gravity falls minus the more ebbing darkness factor, and you add in aliens instead. It's beautiful, and the animation is just as great. The episodes come along more frequently due to the time shortage, and because of the loss of time they waste none of it, putting every second to good use to make it feel like a full-length 30 minute episode just without the stupid filler). 1.2 Invader Zim (Nostalgia prize)
One of the better shows disney has ever put out. Funny at the least, and hilarious at it's best. I recently discovered this show and it is rather interesting. I quite love the animation style.
AN-TAR-ES TIME, COME ON AND GRAB YOUR FRIENDS AND GO TO VERY... "STABLE" LANDS. REZ THE BIRD AND KAZ THE KOBOLD THE ROLEPLAY NEVER ENDS ANTARES TIME~
I always loved the way Adventure Tim e handled complex morals, had episodes based on religion and philosophy, and its ability to subtly tell a greater story Dark Souls style. Who doesn't?
The original Clone Wars mini-series. It was made by Genndy Tartakovsky, who did a lot of the old hits of Cartoon Network, like Dexter's Laboratory, Powerpuff Girls, and Samurai Jack. Also it was amazing.
Adventure time is literally the best ever. My friends think I'm retarded for watching it, but hey, I don't need friends. Powerpuff girls was my show back when I was a kid. Also, samurai jack was great. BUT, the best was JONNY QUEST LIKE YOU CANT BEAT THAT.
