South Park is the greatest show ever created.
Is that the show where a character dies at the end every time?
Well the show revolves around Cartman, Stan, Kyle and of course the one you're thinking of...  Kenny!
I can't say I've ever watched it, but it is supposed to be adult humor, right?
You could certainly say that.  Adult animation is any type of animation work that mainly targets adults.
I used to watch The Simpsons.  They had a lot of adult humor, and political humor.  I haven't watched it in a long time, but I think it still has large following.
The Simpsons are great.  Gotta thank Matt Groening for the creation.
Yes.  Oh, wait.  Why IS it that Kenny dies in South Park all the time?
