My first exposure to Takeshi's Castle was when I was in the US military and stationed in England in the early 2000s. I worked night shift and our shop has this old TV that only picked up a few stations. One of which was a German station that showed nothing but Takeshi's Castle and 900 number commercials. So, we spent our nights watching a insane Japanese game show subtitled in German with a bunch of commercials with topless women.
I watched some of the new Takeshi's Castle with neither subs nor dubs and found it enjoyable regardless. It might be the way I watch anime going forward. Asserting dominance through willful ignorance.
The UK version was narrated by Craig Charles and he really made it better just by adding silly comments over the top. I always used to laugh when the water cannon challenge was on and he would excitedly say "don't let them penetrate your rings"
