TLC - Season 1 Episode 1 Staying Awake

Doctor Flynn starts working at the south Middlesex hospital. He suffers from a series of nightmares, which stem from the complicated operation that caused him to fail his finals first time. Doctor Noble tells everyone in the hospital, and Flynn becomes a laughing stock. A new patient is admitted who sells coffee… a much-desired drug around the hospital, one which Noble swapped Flynn's personalised stethoscope for. To gain the respect of the staff, Flynn makes everyone in the hospital a cup of coffee, only to find out that it is de-caff! Flynn becomes convinced that the coffee rep needs the operation that he failed on, and does it, puncturing the patients lung, just as Mr Ron comes to do the rounds…
