Oscar calls a veterinarian for his pet worm Sesame Street : Season 9 Episode 92

Slimey doesn't look his best today, so Oscar has contacted a vet to make a house. Dr. Purrenbark arrives on the scene and is a bit taken aback; he's never treated a worm before. He proceeds with the examination and finds Slimey has a cold. After recommending a cure, he starts to leave when Oscar asks him to now examine his pet dragon Charlie, who seems to have caught Slimey's cold. Dr. Purrenbark faints.
