Kek, I'm still enjoying it. It's a good laugh and the characters are cute. I did have a feeling that the teacher wasn't normal for quite a while though.
I think Takahama is in the right this time. That cord is clearly a safety hazard, given that Daisuke already tripped over it page 1.
EDIT: Also that open socket on the extension cord with all the melted snow around is an accident waiting to happen
