This episode focuses on the five key sitcoms that shaped the genre: I Love Lucy, The Honeymooners, Make Room for Daddy, The Andy Griffith Show and The Dick Van Dyke Show. The last remaining Honeymooner, Joyce Randolph, speaks candidly about Jackie Gleason's distinctive personality. "The two were just magic together. I don't think that Jackie would have been as great without Art," Randolph says. Similarly, Marlo Thomas offers fascinating insights about her father Danny and the genesis of his Make Room for Daddy sitcom: "My dad used to travel so much, and my mother hated to sleep alone. So we would take turns sleeping in my mother's big huge bed. And we'd bring our toys and our things in there, and then when my dad was about to come home she'd say, 'Make room for daddy.' And we would. And so we said that so much that my father thought that that was a great premise for a show...the idea of making room for this figure that you love that leaves all the time. So that show was pretty much our childhood." Andy Griffith typically avoids TV interviews, but Pioneers of Television producer Steve Boettcher persuaded Griffith to sit for an extended interview—the result is a rare inside look at the people and techniques that made Griffith's show work. The episode also includes interviews with both Mary Tyler Moore and Dick Van Dyke, who recount their years together on the breakthrough Dick Van Dyke Show.
