Saturdays are for cartoons. Somewhere, that is a rule that's written down, and must be obeyed. Sadly, as adults, few of us wake up in the morning to watch our favorite animated shows. Generally, we like to sleep in, and do adult things. Plus, our favorite shows aren't on anymore. Well, this Saturday one of your favorite shows is going to be on all day. And you won't even need cable to watch it.
