Japanese TV is really stupid. But every once in a while there's some sort of accident and they come out with something really funny.
Here is a prank that they are pulling on some people walking down a road. Suddenly, a bunch of people charge around a corner yelling, "Run!" Watch the reactions of the people passing by.
In the first one, with the old guy, they just run by and the old guy has no reaction.
In the second one, they yell, "Tidal wave!"
In the third one they stop and point at the guy and yell, "That's him!"
The others are funny too!
