Well there have been a few anime threads I think, but they sometimes fall good to have anothe one. My favirouts are Death Note, The Melancholy of Haruhi Suzumiya, Azumanga Daioh, Zero no Tsukaima, Hellsing (mostly OVAs but anime was good) and I think most of the tv shows that
Kyoto Animation has done which I have all except for Air. There is also a few ecchi ones that I like, but I am not sure if I should list them, gets a bit embarasing when I my 7 year old brother descides to take a look at what I am watching at an especialy bad time in Rosario + Vampire. One I have been into lately has been Clannad, it is very funny, and makes great references to other anime that Kyoto animation has done, it has been great, but now the psychological element has come in, it almost as bad as the end of School Rumble with how the focus has changed so much from happy, and I will gladely say that I have cried during it.
This is one of my favirout scenes from Azumanga Daioh.

Azumanga Daioh is HILARIOUS!! ! and cute. I've been watching it on that great virtual pirate haven that we call YouTube.
