Come for the effortless charm of Paul Rudd and Justin Theroux but stay for the fart talk. That's right, this episode of "Happy Sad Confused" runs the gamut but what would you expect when Josh is visited by these two hilarious actor/writers? First there's the important stuff. Paul and Justin have re-teamed for a 4th time on screen with their new film, "Mute", a sci-fi noir from the mind of Duncan Jones. But these two can riff on anything and Josh takes full advantage in this chat. Among the topics broached: that distinctive NPR voice, how challenging the luge really is, that time Paul was in a Hong Kong action movie, their favorite underrated comedies, and yes, flatulence.
