As the post-World War II baby boom explodes, an overworked stork gets drunk in the Stork Club, complaining that he does all the work and the fathers get all the credit. Inexperienced animals; among them a dog with a propeller-powered tail carrying bundles of babies, four crows attempting to deliver an elephant, a pelican with simple devices to help haul the babies in its bill, and a mouse dragging a baby rhino; are among those commissioned to handle the increased workload as they take the babies to their parents. Babies are getting sent to the wrong parents; a mother goose is disgusted by her baby skunk, a baby kittenrefuses to swim for its mother duck, a baby gorilla rides uncomfortably in the pouch of a Kangaroo, a Scottie Dog tries to rock his hippo to sleep, and two parents receive offspring that try to eat them—a kitten to a terrified mouse and an alligator to a pig. Porky Pig is brought in to manage Storks Inc. and its assembly line, with Daffy Duck as his assistant. While Daffy mans the phones, making quick references to Bing Crosby, Eddie Cantor and the Dionne Quintuplets' father, Porky runs the control room, contacting references to Roydan Stork, Jimmy Doolittle as Jimmy Doo-quite-a-little, and a B-19. Then a dog worker, apparently research and development, comes into Porky's door and said his skyrocket invention would speed things exponentially, but the rocket exploded before the send-off. It's back to the drawing board for that idea. Then Daffy yells, "Fffull-speed ahead!" and Porky pulled the switch as the babies are seen going through a conveyor belt as they are diapered, fed milk and mechanically burped before they are sent by various animals, one of which is a baby hippo crying loudly and paused as it cutely said, "I'm only 3½ seconds old," before resuming its wailing. Problems, however, occur when Porky, reading the tags from the other babies, finds a stray egg is without an address and decides to have Daffy sit on it until it hatches. However, Daffy refuses to sit around on top of an egg and he said, "Sittin' on eggs is out! O-W-T—Out!!". Porky chases Daffy around the factory until they wind up trapped on the conveyor belt. The belt winds up stuffing both of them into one package and sends them off to Africa via a stork-shaped skyrocket, where a gorilla is waiting for her arrival. When the gorilla looks at the "baby" she sees Daffy Duck crying, Porky peeks through the diaper, saying, "Uh, boo...", causing the gorilla to cry on the telephone, "Mr. Anthony, I have a problem!!". When the alligator is trying to get milk from Mrs. Pig, she starts to say something before it abruptly cuts. According to Bob Clampett, she says “Don’t touch that dial”. It was cut out because The Hays Office deemed it too risqué. No footage has surfaced of the original uncut scene.
