Ira explains that the show is different than usual this week.

Producer Sarah Koenig tells the story of her father, Julian Koenig, the legendary advertising copywriter whose work includes the slogan "Timex takes a licking and keeps on ticking" and Volkswagen's "Think Small" ads. For years Sarah has heard her dad accuse a former partner of stealing some of his best ideas, but until recently she never paid much attention.
