Boss and Me Protect the Boss The Girl Who Sees Scents Rooftop Prince Gu Family Book Arang and the Magistrate Pinocchio Kill Me Heal Me You're Beautiful
Modern Farmeris absolutely hilarious, trust me you wont regret watching it, it is one of my favourite dramas, the OST, the characters, the whole feel of the drama is very light and sweet.
Dramas: My boss my hero Yasuko to Kenj (both of these are more the slapstick kind of comedy) Tiger & Dragon (my absolute favourite of all time, I cried from laughter) You're all surrounded (more detective than comedy drama but hilarious nonetheless)
i second pinocchio, you're beautiful and the girl who sees scents. Oh my ghostess, falling for innocence, birth of a beauty and skip beat!. (skip beat had ALOT of funny moments that cracked me up. especially the director scenes)
I posted for something similar myself not so long back. After recommendations i ave just finished my boss my hero and i was laughing quite a lot. Still think Hana Kimi is the best comedy going though. Japanese dramas in particular are funny (for some reason).
Marriage, Not dating is one of the funniest I have seen. It takes a different approach as well, with random sound effects that were weird at first, but actually added a uniqueness to the series as it went on.
