I love Japanese physical comedy.
While I don't think their bodies will age well, their comedy is simple yet complicated but extremely effective.
I don't think Korea will use these on their comedy shows though. While I can see Lee Su Geun and Kim Byeong Man thriving on physical comedy, this will cause a lot of Korean comedians to get a bunch of injuries.
Anyway, while the seesaw house is safer, it's also unpredictable. Meanwhile, the tilted house is visibly dangerous, but at least you're going to expect the worst.
