Just stumbled across this. I know some eikaiwa veterans are going to protest "no, really, actual eikaiwa is MUCH funnier than this video". But somebody is sinking some serious money into this new series, which appears to be totally professionally produced. It stars Jonathan Sherr (now best known as the actor playing the Tony Laszlo character in the Darin wa Gaikokujin movie) as a new teacher at "Be Yes English School".
Two episodes so far, and worth a watch I think. Next episode due out in a few days.
