It’s a very dumb joke , making fun of a dumb tv show call the good doctor. The writers decided to write a show about a young autistic surgeon, and also decided that his only personality trait would be being a surgeon. There is a scene where he is fired, has a mental breakdown and keeps yelling " I am a surgeon".

Mostly a dumb joke, making fun of writers who wrote the main character of a show based solely of one idea, with no character at all.
