It almost sounds like a movie based off of a King Missile song, Bad Johnson is an upcoming movie about a man who wishes his dong away and instead it becomes a living person. According to Movie Insider

Bad Johnson  stars Cam Gigandet as Rich, a suave Chicago ladies’ man who refuses to take personal responsibility for his inability to maintain a lasting relationship. After his constant infidelities alienate yet another girlfriend (Jamie Chung), he wishes he could say goodbye to his ‘little friend.’ The next morning he awakes in horror to find that his wish has been granted and his penis has taken human form: A disgusting, selfish, oversexed jerk played by comedian Nick Thune. Pitted against his alter ego, Rich must figure out how to rein in his penis, both literally and figuratively, in order to finally learn what separates the men from their boys.
