• Prologue: We hear kids recorded at Chicago's Navy Pier and at a public swimming pool discussing their mean friends. And Ira Glass interviews Lillie Allison, 15, about the pretty, popular girls who were her best friends—until they cast her out. (5 minutes)
• Act One: Jonathan Goldstein interrogates the girls, now grown up, who terrorized him and his classmates years ago in school—and finds they can be just as scary as ever. (18 minutes)
• Act Two: We conduct an experiment to test whether being nice actually pays by equipping two waitresses with hidden microphones to record their interactions. Each waitress is instructed to be super friendly with half of their tables while remaining aloof with the other half. We then compare the tips to see which approach was more profitable. (10 minutes)
• Act Three: A case study in every word from a friend meaning its opposite. (4 minutes)
• Act Four: An excerpt of Bernard Cooper's story about the bill he got from his own father, for the entire cost of his childhood. Actor Josh Hamilton reads. (19 minutes)
