Japanese TV (especially their game shows and reality shows) is notorious for airing some pretty bizarre and cruel stunts. Here are two good examples of that. These videos come from a candid-camera style show. I don't know it's name. In the first video
an outdoor porta potty is equipped with a hydraulic lift that, ten seconds after the door is shut, lifts the bewildered occupant high into the air. And as NetNewsAsia
points out, "for many people, ten seconds is evidently more than enough time to get down to the job at hand."
In the second video
a massaging chair at a ski resort is rigged to send the occupant flying backwards through a trapdoor into the snow. The prank is then updated to make the chair jet-powered. Now its terrified occupants are sent blasting at top speed down the ski slope in a runaway chair.
If these pranks were done in America, I can't imagine someone not getting sued. Assuming, that is, that the pranks haven't been staged (i.e. that the victims aren't really actors). I think there's a good probability that they are. The Japanese have a term for staged events on shows like this: Yarase
. Yarase is so common over there that many viewers just assume that most of the weird stuff they see on TV is fake.
