At the pit of his despair, Larry writes a book titled "A Guide for the Lonely Guy," which is rampantly successful and catapults him into an entirely different experience of life. He becomes rich and famous and even his relationship with Iris can begin on a new basis. Unfortunately, Iris's insecurities return, saying that Larry is now too good for her. She leaves him twice, once after they try to make love and again when they bump into each other on a cruise, where she falls in love with another friend of Larry, Jack (Steve Lawrence).
