In my opinion, comedies are much closer to reality than are dramas. We may, to a certain extent, identify with the characters of dramas but we know dramas are fictions and we next to never actually live situations like those represented in, say, Casablanca, Rain man, Gone with the wind etc. you name them.
Everybody is supposed to be amused with comedies and generally is because comedies resort to a theme that is several thousand years old (to say the least), that is relations between men and women and, contrary to dramas, more or less everybody's concerned here.
In particular, there's an absolute and universal constant within this theme and it is the incredible propensity of men - whatever their age - to behave like they were 15 year old kids if not rightly 7 year old children.
Think of the Simpsons for example where Marge rolls her eyes about ten times in each episode (granted, Homer is hmmm... "different" but yet).
Or TV ads, where men are so often portrayed like irresponsible kids who would be lost without their wives and women are depicted as the real and only grown ups.
Why is it that men are so easily prone to regress and act like helpless creatures who want either to impress their wives/girls friends or arouse the maternal instinct of their partners? Haven't their mothers loved them enough?
And women? Why do they next to never regress and only for several months perhaps but certainly not to the point men do when they eventually act like toddlers? Have their fathers loved them all enough?
Could it be that mothers refuse to hand their sons over to other women and program them like time bomb other women will have to deal with?
Hmmm... life is so complicated. I know what I'm talking about anyway, I'm a great offender myself!
