Another thing, it was very Jewish humour (which, to my amusement, is identified euphemistically as 'New York'.) It may be an acquired taste, I dunno. Well, the humour was Jewish, Jewish producers and writers and Jewish actors and oddly enough, George's Italian parents acting like stereotypical Jewish parents.
Probably had something to do with George's dad being played by Jerry Stiller, another classic Borscht Belt comedian, and real-life father of whats-his-name...
Jewish humor?
