I rarely watch so-called "animes" (referring to Japanese ones), but I'm hooked to these American anime/cartoon series.

Futurama

I love every piece of episodes and this is so much fun to watch. I like Bender in the characters of the series the most.
I feel "isn't it hard for directors to make each episode funny this much?", but they really made this goal.

Bender, made as a bending machine as his name suggests, sings a American country folk "Jimmy Crack Corn".

Disenchantment

This one is made by the same creator "Matt Groening" as was Futurama. My favorite chractor is Elfo.
I feel the depiction of things is realistic, and reckon it may be a cultural thing in English.

"Hi, I'm Elfo!"

Rick and Morty

"A mad scientist and his disciple who gets involved in a doctor's mad and wild adventure" type of cartoon. Every episode is so ingenious and creative. Suppose there are one interesting thing sparsely placed out of 10 things, but this series is like gathered them and condensed altoghether to create one. I feel the US is powerful because there are people with these creative talents. So genius (running out of explanatory words).
