it's just an act for the camera. he sees a majority of his subs like it and find it funny so he keeps doing it, to the point he overdoes it. i used to kinda like the "grandfather joey" voice, but then he started doing it all the time and it lost the bit of humor in it. if you watch his gaming videos, you can see how much he overreacts to things, using the voices and swearing and making up words. he knows a big part of his audience likes it, so he's gonna keep doing it. if you watched lukesarcade back when joey used to play games there all the time, you could see the fans LOVED his reactions, that's why he kept doing them, and why so many of his fans subbed to lukesarcade.
and joey's gaming channel is almost passing lukesarcade in subs, most people subscribed to lukesarcade because of joey and now that he's not there, luke's gaming channel started dying
I take your point, but I lived with a schizophrenic in my first few weeks of uni,the little things he does remind me of many things she used to do. I'm noticing little things that are quite disturbing, I think he may have the start of mental health issues but tries to cover them up and play them out in a comical way, thoughts anyone?
