Delivery Man

Amiable slacker David Wozniak (Vince Vaughn) drives a delivery truck for his family's company and is content with a life of mediocrity. However, when he finds out that he is the biological father of over 500 offspring and many of them are suing to learn his identity, he uncharacteristically decides to hold himself accountable for his actions. He finds some of his progeny and becomes involved in their lives; however, when David's girlfriend announces her pregnancy, she keeps her expectations low. (official distributor synopsis)
