Betty WhiteSo much of the humor on new sitcoms plays to the lowest common denominator. Wit isn't nearly given as much attention as slipping on a banana peel. So much of the writing is so coarse, so obvious that it doesn't provide a shock, never mind a laugh. What makes something funny is alluding to it without laying it out explicitly. You let the audiences fill in the gaps and that's where the laughs come.
