Oh man, Stewie was brutal in that episode; I'd never seen him beat someone up so badly. It was a bit unnerving, actually.I remember an episode on Family Guy where Stewie went after Brian for his money after Brian blew a bet on a boxing match between Channing and a well known boxer. When Brian didn't have the money, Stewie went postal on him to get it. It was the first time I'd seen Stewie in that position to do some actual harm. Until then it was all voice and no action.
I don't tend to watch a lot of the adult themed cartoons or cartoons in general really. If I do catch one it is usually Family Guy (I mean who can resist Stewie?) or Archer. Archer is pretty raunchy and vulgar though since it is on a cable channel and not network television.
I know the origins of The Cleveland Show, Remote, but I just don't care for it.
