Maybe I'm naively romantic but I do believe that spice and excitement doesn't stop once a couple gets together.
Perhaps naively I thought people understand what humor was that it was invented by the human race to cope with the dark areas of life problems and terrors.
I think that everybody in the world whatever colour or creed has a jerk like JR in his or her family somewhere. Whether it is a father uncle cousin or brother everybody can identify with JR and that certainly had something to do with the success of 'Dallas.'
