Gaki no Tsukai question

Hi, I am new to this forum so don’t get mad if I posted it in wrong section (:X), still getting used to this board. I would just like to ask about your opinion on how do you think the gaki no tsukai is edited? Like I saw many videos where for an example the old Hamada’s punishment, where he had to go to Russia to that guy, that slapped him, how Hamada said after that something like "We had to record it so many times, because the slap wasn’t recorded well." and Matsumoto said that this information shouldn’t be known by audience etc. So do you think that most of their shows are really made before and they are just acting ? I always thought that the reactions that they are making are real and not just acted. They would lose a lot of my respect if I am right.

The reason they had to keep recording was because the russian guy couldn’t say his lines properly. It wasn’t really much to do with him.
