Marilyn was ironically one of the most interesting people on Northern Exposure.

If you've seen the show Northern Exposure, then you'd know that Marilyn only spoke in short, simplistic sentences. But, she always managed to get her point across efficiently but using fewer words. Most people would think that she was stupid because of her simplicity of language. Her mind was sharp, she just didn't feel a need for unnecessary linguistics and babbling. Ironically, that made her probably the most interesting character on the show.

Usually, in our modern society the people who talk the most and have the most to say are viewed as being more intelligent. Linguistics and conversational skills are more valued in our Western society.
