The Flintstones

The X-Ray Story (2x15)

Air date: Dec 29, 1961

Ailing Dino is taken to the vet, who diagnoses him as having a "dinopeptic germ," which is common to dinosaurs but lethal in humans. But when Dino's x-rays are mistaken as Fred's, Wilma is alerted and told to prepare the only known cure: keeping the patient awake for seventy-two hours, without telling him why.
