Do you know Japanese tv drama 「nihonjin no shiranai nihongo」? It' s based on Japanese comics of Japanese language teachers. It's not only funny but very helpful to study Japanese, so if you are interested in it, check the website. I'm glad if this information is helpful.
I love this. I just saw the first episode last week. I really love the part where the teachers says 「立って言ってください」and the student says 「た」. But it's very different from the comic. The first seen on the bus is a crack-up.
