This is one of my biggest gripes on Reddit as a whole. I've seen way too many posts and comments griping about how X character is a narcissist, sociopath, bully, etc. for their actions as if they're real people and not characters purposefully written that way for comedic effect. Yeah it would probably be a little annoying if I had a friend as sarcastic as Chandler in real life...but it's a TV show.
