The series starred Lynde as Paul Simms, a general-practice attorney and the father of a family that consisted of his wife Martha (Elizabeth Allen) and daughters Barbara (Jane Actman) and Sally (Pamelyn Ferdin).

It also starred John Calvin as Barbara's husband, Howie Dickerson, an eccentric university student who was of genius intelligence (IQ 185) and was a whiz with everything and full of advice, but inexplicably, he could not manage to hold down a job, and Jerry Stiller and Anne Meara as Howie's divorced parents, Barney and Grace Dickerson.

Howie's misadventures around the house and his lack of steady employment brought his father-in-law to a state of slow-burn anger and drove him to distraction.

Critics perceived the show as derivative of All in the Family, then television's most popular primetime program, and the Paul Simms role bore similarities to Lynde's best-known film role, that of Harry MacAfee from the film and musical Bye Bye Birdie.

Unusual for such a series, the production included a frequently seen backyard set with a fully functional swimming pool, which Lynde would occasionally fall into.
