Judd Apatow is one of the most important influencers of comedy today. In this jam-packed episode, the writer, director and producer of such blockbusters as The 40-Year-Old Virgin, Knocked Up and This Is 40 traces the roots of his love of comedy, from working with giants like Jim Carrey and Gary Shandling who helped him along the way to why he now pays it forward to help launch the careers of so many others like Lena Dunham and Pete Holmes, and how he recently returned to the stand-up stages where he started out.
