Danshi Koukousei no Nichijou (Daily Lives Of High School Boys) is really funny imho. You could also try Nichijou, Barakamon, Lucky Star, and Sket Dance.
- One Punch Man
- Hetalia: Axis Powers
- Ouran Highschool Host Club
- Kiss Him, Not Me
- Everyday Life of Highschool Boys (I forget what the Japanese name is, but the sub is better)
- Fruits Basket
- Blood Lad
- Shimoneta
- Noragami (although it's not all comedy, it has some action and drama in it, but it's pretty funny)
These are just the anime that make me laugh the most~
