Hey no argument here...but it has to be somewhat plausible doesn't it??? 
I mean the whole premise of comedy is that this is something that everyone can identify with and it's taken to the obsurd? 
Is it any less plausible then Fresh Prince of Bel Air, Hogan's Heroes, Bewitched, Red Green, etc? Comedy is not meant to be put under the microscope of reality and I find it interesting that, because of the subject matter, this one is. Could you imagine how popular Mel Brooks would have been if we had all looked at his movies and said, "I don't like it because it isn't realistic"? Using that criteria, every episode of Home Improvement would have taken place in a hospital with Tim Allen in traction.
Humour is very personal and what one person likes another won't, but if you are judging comedy based on how realistic it is then you had better stick to the Discovery channel.
