Who's Your Daddy? (2003)

Something is up in a Rochester, NY, neighborhood: to the consternation of the men, all the babies seem to have the same father. Karl, who's wife Karen has just given birth to a real doll, is disturbed, and he calls a meeting at a local bar of the cuckolds. Steve, a letter carrier, has a theory that he's shared with one of his pals: the perp has to be someone with access to all the wives. Steve has someone in mind, and he runs that idea past their eyes: Mick the milkman. It's vigilante time. Are we men, or are we manikins?
