Hidden cameras about Korean variety shows

It is said that it was agreed in advance to cheat a person. Some people wrote scripts, and some people told them who to cheat. Others decide how to lie to themselves. Sometimes people who are cheated find out and secretly cheat another person with some people. At this time, there will be several hidden cameras, which may have been cheated (but rarely I have only seen them once).

PS。 I still feel a little fake.
