It's A Job Worth Doing (9x2)

:

Still unemployed, Dick parties till all hours, causing Duncan to be late for an operation and throw up on the theatre sister. Duncan decides it's time his friend got a job and makes him fill in the application form. Dick, a reluctant interviewee, does his best to get on the wrong side of chief anaesthetist Wilkinson, but the man loves his cavalier attitude and gives him a job.
