It's actually the Fillerbunny and the side comics that I hate most about him.
I don't think he's funny when he has characters scream "dookie!" a lot. I think a lot of his humor worked better in Invader Zim, because it requires better acting. I think a lot of it doesn't run too well into a comic book.
But he's main plotline, situational, storytelling whathgsdf is great.
