I found this one very funny, maybe just because everything is so over-exeggerated, for instance right from the start with the black student. Or the teachers not knowing things, that even foreigners seem to be aware of, and have learned on their own. And the teacher who is always ranting and fuzzing over about something, hilarious!
By watching the videos, I also found new things to learn more about, such as 花札. I have seen, and even tried to play this game with an SNES Emulator, but can't say that I understood what it is all about. So it was a good opportunity. 
As for the Manga, I read it at ニコニコ静画, or was linked from there to a website, where one can read it. This one is more on the serious side, but an interesting read. Not that I am to judge the quality of Manga, since this was only the second I ever read. In case of this one, also only the parts that have been made freely available, not the whole series. Maybe I am going to order the whole thing, on my next "Japanese material shopping spree".
All in all, it was worth watching it.
