Ah yeah, I remember he made a video in Japanese and also one together with his Japanese grandmother!
It was really cool, especially since he himself said that he feels like his personality changes with the language. (Something I’ve noticed myself, I naturally become slightly more polite/kind in Japanese and more brash in English)
I didn’t know that, though it doesn’t surprise me either Still, from a learner’s perspective it might not make that big a difference.
EDIT: having re-watched the Joey video I noticed that even his own English subs seem harsher than his Japanese speech. Like how ちょっと待って、おかしくねぇ！？ becomes “Wait, what the actual f***!?”
