"Patient Abuse" is a sketch from the final episode of Monty Python's Flying Circus, "Party Political Broadcast".
It was co-written by Python Graham Chapman and his friend Douglas Adams, later known for creating The Hitchhiker's Guide to the Galaxy.
The doctor (Graham Chapman), barely reacting to the blood, blandly asks what the problem is, to which the man responds that the nurse stabbed him.
The sketch ends with the nurse (Carol Cleveland) coming in with a bloody sabre, implying that she has just stabbed the last waiting patient.
The doctor and the nurse decide to "pop[…] out for a bit of lunch", leaving the dying patient with a second form and the promise of some morphine if he gets at least the questions about history right.
