So, just because it's a comedy show, characters can have no limits? You gotta understand that creative brilliance is found within certain frames that artists must work within. Without boundaries, there's no establishment. The Office used to have such a discipline where out-of-character behavior was rare enough to be really entertaining and acceptable when it occurred. Now, it happens so often that you can't even draw much of a connection between who the characters are and what they're doing.

You say "comedy show" as if it's all part of the act, but there's quite a lot that goes on beneath it all. Seinfeld could've gone on for another five seasons if they wanted to, but they called it quits because they knew they reached that same limit The Office hit around season three.
