It's so funny . However, I don't agree this way. Students should participate in the discussion actively. We have to learn how to think critically and how to speak clearly by taking part in a discussion. If we discuss that shocking way, we cannot improve these skills.
"Ken Tanaka fluently Japanese"
I didn't notice we can speak Japanese fluently by saying "shee..." or "hee..."! It's so interesting. Japanese people often use these kinds of words, because we hesitate to response clearly like "yes" or "no". I often use these words unconsciously. By watching that video,however, I notice that it's so funny. I try not to use theses kinds of words in order to make myself understood to everyone clearly.
