I guess the loud rap music didn't go over as well in the classroom. Instead of looking cool, Karl and Sato sensei became the crazy old couple dancing to their crazy old music. Students can be so easy to horrify.
I know it's not that simple to feel rap music if you're not really into it but turning up the volume does help. This comic didn't really happen but I thought that it would be hilarious if a whole office of Japanese teachers started dancing all at once to rap. It was an image in my head that I couldn't get rid of and decided to make a comic about it. You see how silly my mind is?
