I'm just mentioning this, because it seems to me that one of the reasons we love sitcoms, is because (at heart) they are non-threatening places.
Unlike the gritty dramas/stupid dramas we watch, reality (even in "realistic"/mock-doc) is kept to one side.
Which I love.
You watch a sitcom and you never have to deal with the prospects of economic desperation, emotional despair or objectively-real fear of the future. Because, the whole point about proper sitcom - the whole joke - is that nothing can destroy the world that it created. End episode, generally... back to square one.
So, which is the ideal sitcom world in which you'd like to exist?
Who wouldn't want to be a guest at 'Fawlty Towers'? Who wouldn't like to be living with Hancock, a self-sufficient buffoon, but without any seeming money worries? Steptoe & Son always get by. On the other hand, but similarily, life working at Wernham Hogg in 'The Office' generally seems cosy. I'd love to rent at Rigbsy's in 'Rising Damp', or work in the "tedium" of Sunshine Desserts in 'Reggie Perrin'. Worth entering the Catholic priesthood to stay a weekend on Craggy Island with Father Ted? Mighty Boosh fans needn't really explain why they might want to live in their world.
Half the appeal of sitcoms (I think) is that, other than the laughter, they create a world that is safe, dependable, stable - a place that we can feel comfortable in.
Which sitcom would we most like to live in?
As a doctor, I would love to work in 'Darkplace' hospital, for example.
