Takeshi's Castle, the original Japanese show is called, right?
And personally, I don't really like the commentary much at all. I'm more of the sadistic, just-watch-the-people-get-hurt type.
Which never compels me to watch the show, but I don't regret watching when I do.
Those Japanese people either have a great sense of fun or a messed up sense of everything else if they go on a show like that where the prizes are zilch.
