Ten) Veggietales. Great anime. The manga is even better.

Nine) Phineas & Ferb. Very, VERY underated anime. Pure genius.

Eight) Hen'tai. No need for an explanation.

Seven) The Amazing Bulk. Superb animation and characters make it one of my favorite animes.

Six) Spongebob. This is probably the anime that made anime a popular culture staple. Look up "meme" on the internet and you probably won't go ten posts before finding a Spongebob post. That's how big it is.
