Well, Cartoon Network shows some Scooby Doo stuff early in the morning, but otherwise there's nothing. Probably why I sleep until 2 in the afternoon, since all the good shows come on late at night, like Adult Swim. And for some reason Comedy Central doesn't want to show The Critic or Undergrads until 1 am.
TBS shows Futurama and Family Guy in the early afternoon, though- that's about it.
