Tora Dora, the most awesome romance-comedy touching anime I have ever watched. My mistake is, I've watched it first and now I can't find anything better than this.
Ouran High School Host Club, one of the funniest school-based animes I've watched. What I liked about this anime is, Kaoru and Hikaru. I'm always excited to see them in each episodes :[ The funniest was, they actually dyed their hair with pink and blue to prove that they're fighting XD
Nagasarete Airantou, also a funny anime but with a little mix of ecchi. :I It's good too.
Clannad, also an awesome romance-comedy anime. Although the comedy fades as the anime goes on. Which is unique and what I like about this anime.
Yamato Nadeshiko, weeeeeeeeeeee so awesome and hilarious anime.
