Ahahah, School Rumble is definetely hilarious!
So is Ouran Host Club
Durarara!'s absurdity is hilarious as well. It's a must watch!
School Rumble,Full metal panic Fumofu,Hayate no compat butler are few of the most hillarious ones i saw . though i dont know y they didnt make school rumble 3
I have been watching Baka to Test to Shōkanjū and there is not a single episode of that series that I haven’t rofl!! This anime is so epically hilarious!!! All the characters are so funny in their own way. So when all of them combine their LOL powers the result is tons of laughs. The funny moments come from different sources but all of them are awesome. This is definitely one of the funniest anime series I have watched!!
-golden boy is also hilarious. got only 6 episodes but this serie really cracked me up. It's kinda like GTO.
-full metal panic fumoffu is also a good comedy.
I’m rewatching some episodes of Ranma ½, and watching them reminded me of how funny this series is. It is hilarious!! There have been some scenes that had me literally LOL. For instance, I watched some episodes with Ryoga and his poor sense of direction is utterly amusing.
Oh.. oh.. There are a lot of funny anime... but I can't remember them.
Let's see.. Honey and Clover is indeed hilarious.. I remember laughing to tears because of Morita's idiotic behaviour...
oh and Ouran... It's always fun to see Tamaki being bullied by the twins and then was shot by an arrow that is Haruhi's snarks. We are laughing on someone's suffering, eh? But Tamaki always recovers fast anyway...
Fairy Tail is sometimes hilarious too... I often find myself switching from crying to laughing in matter of seconds.
Soul Eater is sometimes funny too...There were many episodes where I had to stop watching because I couldn't handle the laugh that was coming out of my mouth...
Hetalia is my favorite hilarious anime, though sometimes I don't understand some of the jokes.. especially European jokes.. But every eps is hilarious and silly. It can always brighten my gloomy days with the characters' silly behaviors.
and I don't remember what else...
When I went to Japan in 2004, I laughed so much watching Bo-bobo on television. Maybe my humor was a bit off beat then, but I remember my brother and I were in hysterics.
Right now the funniest anime I've watched is Sayonara Zetsubou Sensei. Its humor that you have to wrap your head around, and I love how it makes a satire out of Japanese culture and society.
Danshi Koukousei no Nichijou.
It is one of the anime series that I’m currently watching and it is very, very funny. I can’t pinpoint where the hilariousness comes from; maybe from the RL/funny situations the characters go through, or the clever/witty one-liners, or maybe it is the fact that the hilarious situations sometimes seem to close to RL…I don’t know, I only know that DKN is one of the funniest series of this winter anime season.
Ixion Saga DT
While it is true that this series has had its ups and downs and it is also true that there has been moments where I was very close to drop it, one fact is undeniable and that is the fact that it is one of the funniest series I have watched. A couple of episodes in this series have been pure comedy gold! Ixion’s sense of humor might not appeal to everyone, but if it is your kind of humor then you’ll definitely enjoy this series.
I thought Yakitate!! Japan was pretty funny. It's an anime about bread, but well...you'll just have to watch it to see how funny it can be xD
Ah, now I remember that Polar Bear Cafe is hilarious too... I like to watch it when I'm depressed to lift up my mood.
Oreimo was the funniest series I have seen in a long time. Kirino, the main character, is the perfect combination of raging tsundere and perfect fangirl. Kyousuke is the perfect foil, with a personality similar to Haruhi's Kyoun and Hyouka's Oreki (same voice actor). Kuroneko is as memorable as the two leads, and just as funny.
