Yeah, it is funny and doable in Japan. I don't think it would go over so
well here. Can you imagine a whole hord of teenagers running after someone
like cjsha? He'd get his gun out and shot a couple...
I probably would have ducked and covered with the crowd. I think I would have attempted to get to the side and avoid the crowd running at me though. I can't see myself turning around and running with them. I figure the guy they tossed around they knew; however since there are only a tiny number of attorneys in Japan compared to the USA, they must not worry about lawsuits as much there.
The Japanese definitely have a flair for elaborate practical jokes.
