Hands down, Gintama. Honorable mentions: Nichijou, Konosuba, Hinamatsuri, and others.
Without a doubt, Shimoneta was the funniest anime I’ve seen. Not gonna be in my top ten cause the anime overall was meh in my opinion, but the comedy was always great. They even had a bit where they instructed viewers on how to make a homemade fleshlight.
I think Nichijou and Danshi Kokosei no Nichijo made me laugh the most ^^
Recently it’s been Zombieland Saga
probly Great Teacher Onizuka, Papuwa Island, & Prison School.
KonoSuba/KonoSuba 2 (I found KonoSuba 2 had my sides splitting, but you'd need to watch the first I think.. maybe).
