Television series about the lives of a real family, The Nelsons, as they cope with everyday life. Ozzie is the bumbling father whose earnest intentions backfire hilariously in their execution; Harriet is the apron-clad, flawlessly coiffed, wise and loving Mom; David is the older and more grounded brother; Ricky (later to become "Rick") is the wisecracking scamp of a kid brother who sings.
