"Small Potatoes" is the twentieth episode of the fourth season of the American science fiction television series The X-Files. It premiered on the Fox network in the United States appropriately on April 20, 1997 (4/20, also the number of the season/episode). It was written by Vince Gilligan and directed by Cliff Bole. The episode is a "Monster-of-the-Week" story, unconnected to the series' wider mythology. "Small Potatoes" received a Nielsen rating of 13.0 and was viewed by 20.86 million people in its initial broadcast. The episode received positive reviews from critics, with many applauding the entry's humorous tone. The show centers on FBI special agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson), who work on cases linked to the paranormal, called X-Files. Mulder is a believer in the paranormal, and the skeptical Scully has been assigned to debunk his work. In this episode, a small town is “blessed” by babies being born with tails. Mulder and Scully arrive only to encounter a suspect, Eddie Van Blundht (Darin Morgan), who proves nearly impossible to identify. "Small Potatoes" was written by Gilligan in an attempt to write a lighthearted episode; he did not want to develop a reputation for only writing dark stories. Gilligan asked former series writer Darin Morgan, who had penned four episodes in the second and third seasons, to play Eddie Van Blundht. In fact, the role was written specifically with Morgan in mind. In the original script, the babies were born with wings instead of tails. The effect was eventually changed to tails, because, according to Gilligan, they were funnier. Plot Agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) investigate the birth of five babies in the town of Martinsburg, West Virginia, who were born with tails. The mother of the most recent baby, Amanda Nelligan, tells the agents that the father of her baby is Luke Skywalker. By researching the baby's chromosomes it is discovered that all five share the same father. The parents of the children blame the local fertility doctor, who had used insemination to impregnate all of the mothers but Nelligan. Mulder spots a janitor nearby with signs that he formerly had a tail. When he runs, Mulder chases him and catches him. The janitor, Eddie Van Blundht, is discovered to be the father of all of the children. Scully believes Eddie used a date rape drug although Mulder questions how
