This chap reminds me of some "weird speech pattern" Moment
I've saw vid about how plenty of foreigners with Japanese wife ended up sounding like a gay man because they learned Japanese from their wife, thus imitating their feminine speech pattern
There's also that Chinese guy who became an "internet sensation" A while back because he passed Japanese language test (at N3 iirc) from years of watching JAV, I wonder what he sounds like to the native Japanese speaker..
