Yeah, as far as slice-of-life shows go, Azumanga Daioh is the only one I've really found funny because it feels like the only one willing to find all its humor in what's actually the mundane (Isn't that why we call the damn things slice-of-life?). A lot of the other shows have annoying over-the-top shit like the above to force laughs out of the audience.
Fumoffu's sort of the opposite end, I guess, and I liked that too, for the most part.
And, as serious Welcome to the NHK can get, it still plays out as a comedy for the most part, so maybe I'd take a look there.
