The Flintstones S02E15 - The X-Ray Story

Dino's x-rays are mistaken for Fred's. As a result, Wilma, Betty, and Barney think Fred has the illness Dino has ("dinopeptitis"). This causes them to keep Fred awake for 24 hours straight and take a trip to the roller skating rink, where Fred falls asleep on his skates despite having twenty or thirty cups of coffee.
