This show is not very funny. Maybe what I expected of it was way too high going in to watching it just now for the first time because my friend and his wife both said it was good but I don't think so, I just don't think I find this show or this kind of humor very funny. I don't like the guy who plays Mr. D either he comes off like he is trying way too hard to channel Steve Carell from the Office and trying way too hard to be funny with the lines he has.
I think my friends mostly like it because they are both teachers. I assume there is stuff in this show that teachers can see that the rest of us can not because the guy playing Mr. D apparently based this show on being a teacher because he used to be one. Any how I just don't think it is very funny. I like the kids though they are pretty good considering their age.
