“[A] penis looks like a man with a big nose and large ears. It’s a vulnerable area, so it’s good for comedy. But you have to be very careful about how much you show. I learned this from working on Forgetting Sarah Marshall, in which Jason Segel is naked for an entire scene…. When you show a movie with full-frontal nudity to a test audience, you instantly learn how many seconds of screen time results in how many audience members walking out of the theater. You may get away with three seconds of penis exposure, but at five seconds you’ll lose 18 people. At 10 seconds it could be a hundred. The fear of the penis in modern society is unparalleled.” – Funny People writer-director Judd Apatow to Playboy‘s Eric Spritznagel.
