I have two "cartoons" I love to watch. Yeah, yeah, I know. They're call animes nowadays. As I mentioned not long ago, I watch VAMPIRE KNIGHT. The anime is about a school girl who has a crush on a vampire. Well, there's a whole lot more to it and you can check it out at Hulu.com.
The other one is Archer on FX. You can watch the episodes on Hulu.com too. It's for adults only as the language and situations are rather naughty but so funny.
