Dry humor is an acquired taste, and if you're a fan of that kind of humor and a fan of Newhart, this is for you. Great banter among the characters, good Chicago references (there weren't many TV shows set in Chicago at that time) and situations that have held up surprisingly well over time make this an underrated show worth taking a look at. Too bad this show didn't last longer, but the cast and producers decided to go out while on top rather than wear out their welcome.
