Huh? Only four shows have been animes. Considering the fact that there are
a lot of animes (as far as I know, Japan doesn't even produce anything else), I'd call it "cultural diversity" to actually have shows from countries outside of the US on there. And no, Avatar is not anime, though it's sometimes called an "amerime."

What do you have against anime anyway?
Oh yeah, and I say BB still has a chance. You'd think JL(U) would be higher than it, but you'd also think South Park would be higher than Invader Zim. And I'm sure TSSM is going to be in there, probably in the Top Five, maybe even #1 (that or Simpsons, I'd think).
Phineas and Ferb: Only saw one episode. Wasn't impressed.
Full Metal Alchemist: Should've been higher. Why? Because one of the episodes (not saying which for those who haven't seen it, but fans of the show should know which one I'm referring to) has to be the most powerful thing I've ever seen on television - that includes cartoons, live-action, and maybe even movies. This series is absolutely amazing.
