Yang Zhang/Accented Cinema does a good job at exactly, in a technical manner, why Stephen Chow's brand of humour works so well with me and why sometimes I literally do ROFL and LSHIACU (Laugh So Hard I Also Cry Uncontrollably) when watching his films. I think it certainly is a very niche cultural thing.
I have played Stephen Chow films for friends before and most of the time, they obviously lose interest fast. Some of the ones that do continue watching laugh weirdly hard before the actual punchline for whatever reasons. Not giggle or smirk like something was amusing, but ribs hurting, ugly crying laughter. I genuinely can't tell it's over the top sarcasm or if something in the setup of the joke really seemed like the punchline to them.
