joey's so different in the first few seasons, i think he was meant to be a little more suave and sarcastic, but they made him dumber coz the audience loved it
Well I think they also realized Chandler was better at being sarcastic and Joey though always a ladies man was funnier being stupid which is kind of a thing with any long running sitcom; there is going to be a character who gets dumber and dumber the longer it goes on.
because it's fun. keep in mind this is youtube, which isn't a place to be serious. quotes always get liked because after you watch the video you see them and laugh at that moment or you look at them beforehand and look for that moment in the video and sometimes they quote something you missed the first time you watched it. it;s just for fun, like most of youtube
Probably Chandler admitting though he obviously still likes and wants to date/be with woman sometimes having a desire to also be a woman. Obviously one that isn't that strong but considering what we find out about his father later on obviously one that came from somewhere.
